Microsoft office interop word application word

Большинству операций, выполняемых программным способом, есть эквиваленты в пользовательском интерфейсе (UI), доступные как команды в меню и на панелях инструментов. Также существует нижележащая архитектура, обеспечивающая поддержку команд, выбираемых из UI. Всякий раз, когда вы создаете новый документ Word, он базируется на каком-либо шаблоне; расширение файлов шаблонов «.dot», а файлы документов – «.doc». Шаблон Word может содержать текст, код, стили, панели инструментов, элементы автотекста, комбинации клавиш для быстрого доступа к командам. Новый документ связывается с шаблоном и получает полный доступ к его элементам. Если вы не указываете конкретный шаблон, новый документ создается на основе стандартного шаблона «Normal.dot», который устанавливается при установке Word).

Шаблон Normal.dot является глобальным, он доступен любому документу, который вы создаете. Вы могли бы при желании поместить весь свой код в Normal.dot и создавать все документы в своей среде на основе собственного шаблона Normal (Обычный). Но тогда его файл мог бы стать чрезмерно большим, поэтому более эффективное решение для многих разработчиков — создание собственных шаблонов для конкретных приложений. В документах, создаваемых на основе вашего шаблона, код из стандартного шаблона Normal по-прежнему будет доступен. При необходимости можно связывать документ с несколькими шаблонами в дополнение к шаблону Normal.

Для работы с приложением Microsoft Word в .NET, используется объект Application, который является предком всех остальных объектов. Получив на него ссылку, вы можете работать с его методами и свойствами. Этот объект предоставляет большой набор методов и свойств, позволяющих программным путем управлять Microsoft Word. Код инициализации нового объекта Application, представлен ниже.

Microsoft.Office.Interop.Word.Application winword = 
  new Microsoft.Office.Interop.Word.Application();

Чтобы открыть существующий документ или создать новый, необходимо создать новый объект Document.

object missing = System.Reflection.Missing.Value;
Microsoft.Office.Interop.Word.Document document =
     winword.Documents.Add(ref missing, ref missing, ref missing, ref missing);

Выполняя какую-либо операцию в пользовательском интерфейсе Word (например, добавляя верхний колонтитул), вы выделяете соответствующую секцию, используя объект «Selection», определяющий текущую позицию «невидимого» курсора и применяете к ней новый параметр форматирования с использованием объекта «Range». Данный объект представляет область в документе и может включать в себя все что угодно — от пары символов, до таблиц, закладок и много другого. Вы не ограничены одним объектом «Range» — в одном документе можно определить сразу несколько таких объектов.

//Добавление верхнего колонтитула
foreach (Microsoft.Office.Interop.Word.Section section in document.Sections)
{                   
    Microsoft.Office.Interop.Word.Range headerRange = 
    section.Headers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range;
    headerRange.Fields.Add(headerRange, Microsoft.Office.Interop.Word.WdFieldType.wdFieldPage);
    headerRange.ParagraphFormat.Alignment = 
    Microsoft.Office.Interop.Word.WdParagraphAlignment.wdAlignParagraphCenter;
    headerRange.Font.ColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdBlue;
    headerRange.Font.Size = 10;
    headerRange.Text = "Верхний колонтитул" + Environment.NewLine + "www.CSharpCoderR.com";
}

//Добавление нижнего колонтитула
foreach (Microsoft.Office.Interop.Word.Section wordSection in document.Sections)
{                   
    Microsoft.Office.Interop.Word.Range footerRange =
   wordSection.Footers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range;
    
    footerRange.Font.ColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdDarkRed;
    footerRange.Font.Size = 10;
    footerRange.ParagraphFormat.Alignment = 
    Microsoft.Office.Interop.Word.WdParagraphAlignment.wdAlignParagraphCenter;
    footerRange.Text = "Нижний колонтитул" + Environment.NewLine + "www.CSharpCoderR.com";
}

Чтобы добавить текст в документ, необходимо указать позицию для вставки и сам текст.

//Добавление текста в документ
document.Content.SetRange(0, 0);
document.Content.Text = "www.CSharpCoderR.com" + Environment.NewLine;

Так же вы можете применить к тексту определенный стиль.

//Добавление текста со стилем Заголовок 1
Microsoft.Office.Interop.Word.Paragraph para1 = document.Content.Paragraphs.Add(ref missing);
object styleHeading1 = "Заголовок 1";
para1.Range.set_Style(styleHeading1);
para1.Range.Text = "Исходники по языку программирования CSharp";
para1.Range.InsertParagraphAfter();

В классе Microsoft.Office.Interop.Word.Document, присутствует коллекция «Tables», которая позволяет добавить таблицу в документ с использованием метода Add.

//Создание таблицы 5х5
Table firstTable = document.Tables.Add(para1.Range, 5, 5, ref missing, ref missing);

firstTable.Borders.Enable = 1;
foreach (Row row in firstTable.Rows)
{
    foreach (Cell cell in row.Cells)
    {
        //Заголовок таблицы
        if (cell.RowIndex == 1)
        {
            cell.Range.Text = "Колонка " + cell.ColumnIndex.ToString();
            cell.Range.Font.Bold = 1;
            //Задаем шрифт и размер текста
            cell.Range.Font.Name = "verdana";
            cell.Range.Font.Size = 10;                                                     
            cell.Shading.BackgroundPatternColor = WdColor.wdColorGray25;
            //Выравнивание текста в заголовках столбцов по центру
            cell.VerticalAlignment = 
                 WdCellVerticalAlignment.wdCellAlignVerticalCenter;
            cell.Range.ParagraphFormat.Alignment = 
                 WdParagraphAlignment.wdAlignParagraphCenter;
        }
        //Значения ячеек
        else
        {
            cell.Range.Text = (cell.RowIndex - 2 + cell.ColumnIndex).ToString();
        }
    }
}

Для функционирования описанного выше кода, необходимо добавить к текущему проекту объектную библиотеку MS Word. Перейдите в меню «Проект» и выберете команду «Добавить ссылку» или в обозревателе решений, найдите пункт «Ссылки» и сделайте клик правой клавишей мыши по нему, из появившегося контекстного меню выберете соответствующий пункт.

В открывшемся окне «Добавить ссылку», перейдите на вкладку «COM» и выберете «Microsoft Word 14.0 Object Library» из предложенного списка библиотек.

В обозревателе решений у вас появится ссылка на данную библиотеку.

Перейдите в конструктор главной формы и добавьте из панели элементов, командную кнопку «Button». Данный элемент необходим для запуска процесса создания документа и вызов MS Word для отображения.

Сделайте двойной клик левой клавишей мыши по элементу «Button» и вы перейдете в автоматически созданный метод события «button1_Click». Добавьте в него приведенный ниже код.

Запустите ваш проект, нажав на клавиатуре, клавишу «F5». Нажмите на единственную кнопку, расположенную на главной форме вашего проекта. У вас автоматически откроется документ Microsoft Word с заполненным верхним и нижним колонтитулом, обычным и с применением стиля текстом, а так же заполненной таблицей.

Для сохранения документа в определенной директории, добавьте приведенный ниже код, после строки «winword.Visible = true;».

//Сохранение документа
object filename = @"d:temp1.docx";
document.SaveAs(ref filename);
//Закрытие текущего документа
document.Close(ref missing, ref missing, ref missing);
document = null;
//Закрытие приложения Word
winword.Quit(ref missing, ref missing, ref missing);
winword = null;

При работе с приложением Word в памяти компьютера создается отдельный процесс, если его не закрыть или не вывести созданный документ на экран, то он будет работать до выключения компьютера. Так же при постоянной работе с такими документами, их процессы будут накапливаться незаметно для пользователя, что может привести к зависанию компьютера или другим последствиям.

The C# programming language includes capabilities that make working with Microsoft Office API objects easier. With the advent of named and optional arguments, introduction of the dynamic type in .NET, and the ability to pass arguments to the reference parameters in COM methods, C# 4.0 quickly became the language of choice for working with COM and Interop objects.

This article talks about office interop objects in C# and how you can use them to interact with Microsoft Word and Microsoft Excel. Code examples are also provided to illustrate the concepts covered.

Prerequisites for working with Interop Objects

Visual Studio 2019 or Visual Studio 2022 must be installed on your computer to work with the code samples demonstrated in this C# tutorial. In this example, we will be using Visual Studio 2022. If you don’t have it installed in your computer, you can download it from here.

As of this writing, Visual Studio 2022 RC 2 has been released. You should also have Microsoft Office Excel 2007 or Microsoft Office Word 2007 (or their later versions) installed on your computer.

How to Program Office Interop Objects in C#

In this section we will examine how to work with Office Interop objects and use them to connect to Microsoft Word and Excel and read/write data.

You must add the following using directives in your program for working with Word and Excel respectively when using Office interop objects:

using Microsoft.Office.Interop.Excel;
using Microsoft.Office.Interop.Word;

Working with Excel Interop Objects in C#

To begin, create a new Excel document named Test.xslx as a sample Excel file present in the root directory of the D:> drive. We will use this file in the following example.

You should create an instance of the Application class pertaining to the Microsoft.Office.Interop.Excel library for communicating with Excel. To do this, write the following C# code:

Application excelApplication = new Application();

The next step is to create an instance of the Workbook class to access a Workbook in Excel. You can create an instance of Workbook using the following code:

Workbook excelWorkBook = excel.Workbooks.Open(@"D:Test.xslx");

To read the name of the workbook, you can use the Name property of the workbook instance as shown in the code snippet given below:

string workbookName = excelWorkBook.Name;

The following code listing illustrates how you can display the value of the first cell of the first worksheet of the Excel document:

int worksheetcount = excelWorkBook.Worksheets.Count;
if (worksheetcount > 0) {
  Worksheet worksheet = (Worksheet) excelWorkBook.Worksheets[1];
  string worksheetName = worksheet.Name;
  var data = ((Range) worksheet.Cells[row, column]).Value;
  Console.WriteLine(data);
} else {
  Console.WriteLine("No worksheets available");
}

Here’s the complete code listing for your reference:

using Microsoft.Office.Interop.Excel;
using Microsoft.Office.Interop.Word;
using System;
using System.Runtime.InteropServices;

namespace OfficeInteropDemoApp
{
    class Program
    {
        static void Main(string[] args)
        {
            string filename = @"D:Test.xlsx";
            DisplayExcelCellValue(filename, 1, 1);
            Console.Read();
        }

        static void DisplayExcelCellValue(string filename, 
        int row, int column)
        {
            Microsoft.Office.Interop.Excel.Application 
            excelApplication = null;
            try
            {
                excelApplication = new 
                Microsoft.Office.Interop.Excel.Application();
                Workbook excelWorkBook = 
                excelApplication.Workbooks.Open(filename);
                string workbookName = excelWorkBook.Name;
                int worksheetcount = excelWorkBook.Worksheets.Count;

                if (worksheetcount > 0)
                {
                    Worksheet worksheet = 
                   (Worksheet)excelWorkBook.Worksheets[1];
                    string firstworksheetname = worksheet.Name;
                    var data = ((Microsoft.Office.Interop.Excel.Range)
                    worksheet.Cells[row, column]).Value;
                    Console.WriteLine(data);
                }
                else
                {
                    Console.WriteLine("No worksheets available");
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            finally
            {
                if (excelApplication != null)
                {
                    excelApplication.Quit();
                    Marshal.FinalReleaseComObject(excelApplication);
                }
            }
        }
    }
}

Refer to the code listing given above. Note, the finally block of the DisplayExcelCellValue method. The Quit method is called on the Excel application instance to stop the application. Finally, a call to Marshall.FinalReleaseComObject sets the reference counter of the Excel application instance to 0.

The following code listing illustrates how you can create a new Excel document using Office Interop in C#. Note how a new workbook has been created:

static void CreateExcelDocument() 
{
	Microsoft.Office.Interop.Excel.Application excelApplication = null;

	try {
		excelApplication = new 
            Microsoft.Office.Interop.Excel.Application();
		Workbook excelWorkBook = excelApplication.Workbooks.Add();
		Worksheet worksheet = (Worksheet) excelWorkBook.Worksheets[1];
		worksheet.Cells[1, 1] = "Product Id";
		worksheet.Cells[1, 2] = "Product Name";
		worksheet.Cells[2, 1] = "1";
		worksheet.Cells[2, 2] = "Lenovo Laptop";
		worksheet.Cells[3, 1] = "2";
		worksheet.Cells[3, 2] = "DELL Laptop";
		excelWorkBook.SaveAs(@"D:Test.xls");
	}
	catch(Exception ex) {
		Console.WriteLine(ex.Message);
	}
	finally {
		if (excelApplication != null) {
			excelApplication.Quit();
			Marshal.FinalReleaseComObject(excelApplication);
		}
	}
}

When you run this code, a new Excel document will be created at the path specified with the following content inside:

Working with Word Interop Objects in C#

To work with Microsoft Word, you would need to create an instance of Microsoft.Office.Interop.Word.Application. Like Excel, this instance would be used to communicate with a Word document.

Microsoft.Office.Interop.Word.Application wordApplication = new Microsoft.Office.Interop.Word.Application();

The next step is to create a document instance using the Documents property of the Microsoft.Office.Interop.Word.Application instance we just created, as shown in the C# code snippet given below:

wordApplication.Documents.Add();

Next, you can create a paragraph and add some text to it using the as shown in the code snippet shown below:

var paragraph = document.Paragraphs.Add();
paragraph.Range.Text = "This is a sample text to demonstrate how Interop works...";

Then you can save the Word document using this code:

wordApplication.ActiveDocument.SaveAs(@"D:Test.doc", WdSaveFormat.wdFormatDocument);

Here is the complete code listing showing how to work with Microsoft Word Interop Objects in C# for your reference:

using Microsoft.Office.Interop.Excel;
using Microsoft.Office.Interop.Word;
using System;
using System.Runtime.InteropServices;

namespace OfficeInteropDemoApp
{
    class Program
    {
        static void Main(string[] args)
        {
            string filename = @"D:Test.doc";
            CreateWordDocument(filename);
            Console.Read();
        }

        static void CreateWordDocument(string filename)
        {
            Microsoft.Office.Interop.Word.Application 
            wordApplication = null;
            try
            {
                wordApplication = new 
                Microsoft.Office.Interop.Word.Application();
                var document = wordApplication.Documents.Add();
                var paragraph = document.Paragraphs.Add();
                paragraph.Range.Text = "This is a sample text to 
                demonstrate how Interop works...";
                wordApplication.ActiveDocument.SaveAs(filename, 
                WdSaveFormat.wdFormatDocument);
                document.Close();

            }
            finally
            {
                if (wordApplication != null)
                {
                    wordApplication.Quit();
                    Marshal.FinalReleaseComObject(wordApplication);
                }
            }
        }
    }
}

To read a Word document and display each word of the document you can use the following C# code:

static void ReadWordDocument(string filename)
        {
            Microsoft.Office.Interop.Word.Application 
            wordApplication = null;
            try
            {
                wordApplication = new 
                Microsoft.Office.Interop.Word.Application();
                Document document = 
                wordApplication.Documents.Open(filename);

                int count = document.Words.Count;
                for (int i = 1; i <= count; i++)
                {
                    string text = document.Words[i].Text;
                    Console.WriteLine(text);
                }
            }
            catch(Exception ex)
            {
                Console.Write(ex.Message);
            }
            finally
            {
                if (wordApplication != null)
                {
                    wordApplication.Quit();
                    Marshal.FinalReleaseComObject(wordApplication);
                }
            }

Note how the Words property of the Word application instance has been used to retrieve the words contained in the document.

C# Interop Objects Tutorial

In this article we have examined how we can access Microsoft Office Interop objects using C#. Since there is still no support for working with Interop objects in .NET Core, we have created a .NET Framework Console Application in this example.

This article shows how to create a Word document using C# and Office 2013.

Step 1: Create a simple Windows application and place a button control in it.

Step 2: Double-click the button control and go to the code widow.

Step 3: Add a reference for «Microsoft.Office.Interop.Word» as shown in the following image.

Step 4: Copy and paste the following code to generate the Word document.

The code is self-explanatory and the required comments are added wherever they are required.

private void button1_Click(object sender, EventArgs e)
{
CreateDocument();
}
private void CreateDocument()
{
try
{
Microsoft.Office.Interop.Word.Application winword = new Microsoft.Office.Interop.Word.Application();
winword.ShowAnimation = false;
winword.Visible = false;
object missing = System.Reflection.Missing.Value;
Microsoft.Office.Interop.Word.Document document = winword.Documents.Add(ref missing, ref missing, ref missing, ref missing);
foreach (Microsoft.Office.Interop.Word.Section section in document.Sections)
{
Microsoft.Office.Interop.Word.Range headerRange = section.Headers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range;
headerRange.Fields.Add(headerRange, Microsoft.Office.Interop.Word.WdFieldType.wdFieldPage);
headerRange.ParagraphFormat.Alignment = Microsoft.Office.Interop.Word.WdParagraphAlignment.wdAlignParagraphCenter;
headerRange.Font.ColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdBlue;
headerRange.Font.Size = 10;
headerRange.Text = «Header text goes here»;
}
foreach (Microsoft.Office.Interop.Word.Section wordSection in document.Sections)
{
Microsoft.Office.Interop.Word.Range footerRange = wordSection.Footers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range;
footerRange.Font.ColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdDarkRed;
footerRange.Font.Size =10;
footerRange.ParagraphFormat.Alignment = Microsoft.Office.Interop.Word.WdParagraphAlignment.wdAlignParagraphCenter;
footerRange.Text = «Footer text goes here»;
}
document.Content.SetRange(0, 0);
document.Content.Text = «This is test document «+ Environment.NewLine;
Microsoft.Office.Interop.Word.Paragraph para1 = document.Content.Paragraphs.Add(ref missing);
object styleHeading1 = «Heading 1»;
para1.Range.set_Style(ref styleHeading1);
para1.Range.Text = «Para 1 text»;
para1.Range.InsertParagraphAfter();
Microsoft.Office.Interop.Word.Paragraph para2 = document.Content.Paragraphs.Add(ref missing);
object styleHeading2 = «Heading 2»;
para2.Range.set_Style(ref styleHeading2);
para2.Range.Text = «Para 2 text»;
para2.Range.InsertParagraphAfter();
Table firstTable = document.Tables.Add(para1.Range, 5, 5, ref missing, ref missing);
firstTable.Borders.Enable = 1;
foreach (Row row in firstTable.Rows)
{
foreach (Cell cell in row.Cells)
{
if (cell.RowIndex == 1)
{
cell.Range.Text = «Column « + cell.ColumnIndex.ToString();
cell.Range.Font.Bold = 1;
cell.Range.Font.Name = «verdana»;
cell.Range.Font.Size = 10;
cell.Shading.BackgroundPatternColor = WdColor.wdColorGray25;
cell.VerticalAlignment = WdCellVerticalAlignment.wdCellAlignVerticalCenter;
cell.Range.ParagraphFormat.Alignment = WdParagraphAlignment.wdAlignParagraphCenter;
}
else
{
cell.Range.Text = (cell.RowIndex — 2 + cell.ColumnIndex).ToString();
}
}
}
object filename = @«c:temp1.docx»;
document.SaveAs2(ref filename);
document.Close(ref missing, ref missing, ref missing);
document = null;
winword.Quit(ref missing, ref missing, ref missing);
winword = null;
MessageBox.Show(«Document created successfully !»);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

Step 5: Once the code is executed successfully, the document output will be:

The source code is attached, please post your feedback in the comments section.

Hope this helps someone.

Question
I’m looking at someone else’s code C# and it includes:

Microsoft.Office.Interop.Word._Application WordApp = new Microsoft.Office.Interop.Word.Application();

and also

WordApp.Quit(ref oFalse, ref oEmptyItem, ref oEmptyItem);

I can’t find any documentation on

Microsoft.Office.Interop.Word.Application

but I can find some about:

ApplicationClass and its Quit Method

Is ApplicationClass what is being referered to by Application above?

If so, how come?

Also, both ApplicationClass and ApplicationClass. Quit Method have the note:

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Is the code author doing something he should have done or am I missing something (very likely)

I’d realy appreciate some comments since reading is not getting me any place.

Thanks

Hi calgeo

you’re not doing anything wrong, really. The problem comes from an ambiguity in the names of an event and a method. This, again, is due to how .NET imports and interprets the COM library of an Office application.

Is this an error, or just a warning (IOW will the code compile and run)? I’d normally expect this to be a warning, that can safely be ignored. To use the
event, you’d need to explicitly declare the namespace, as in the message.

Here are some links that may help you follow what’s going on

http://social.msdn.microsoft.com/forums/en-US/csharpgeneral/thread/90fa8541-316e-4fac-9885-7c28ef9653b1/
http://msdn.microsoft.com/en-us/library/aa163989(office.10).aspx
http://support.microsoft.com/kb/315981/en-us

Note: this last explains the situation for VB.NET, but falls into the same error of using ApplicationClass or _Application. Apply the principle for the first suggestion (of type casting), if you don’t want to see the error.

Tried:

((Microsoft.Office.Interop.Word.

_Application)WordApp).Quit();

Gets rid of the error but am I forcing it to use a Quit that I’m not suppose to use?

There no «do not use» with the

_Application.Quit Method
doc.

I don’t see anything about the default for
SaveChanges

Can I name the application?

Thanks a lot!

Hi Calgeo

You’ll need to ask in a WinForms forum about changing what the Task Manager shows for your WinForms application — I can’t help you with that.

Generally, I use Quit without arguments (in the case of C#, you probably have to pass «Missing» to have Word use the default), or I tell it to save changes. But you have to know what you want the application to do if any documents have changes that haven’t
been saved. That’s not something I can answer for you.

<< Back to C-SHARP

Use Microsoft.Office.Interop.Word. Open a DOC file and read the text in it.

Microsoft Word can be used with C# code. You have a Microsoft Word document (.doc) and want to read it in your C# program. With the Microsoft.Office.Interop.Word assembly, we get the contents and formatting from the document.

Tip: Add the Microsoft.Office.Interop.Word assembly to your project. Go to Project -> Add Reference.

Example. First, we show the file we will read. It contains three paragraphs containing one word each. The program first instantiates an Application instance and then we call Documents.Open on that variable.

Next: We loop through the Words collection and read the Text property on each element. We then display and call Quit.

Word document: word.doc

One

Two

three

C# program that uses Microsoft Word interop

using System;
using Microsoft.Office.Interop.Word;

class Program
{
static void Main()
{
// Open a doc file.
Application application = new Application();
Document document = application.Documents.Open(«C:\word.doc»);

// Loop through all words in the document.
int count = document.Words.Count;
for (int i = 1; i <= count; i++)
{
// Write the word.
string text = document.Words[i].Text;
Console.WriteLine(«Word {0} = {1}», i, text);
}
// Close word.
application.Quit();
}
}

Output

Word 1 = One
Word 2 =
Word 3 = Two
Word 4 =
Word 5 = three
Word 6 =

Empty paragraphs. We see that Word 2, Word 4, and Word 6 are empty. The empty paragraphs in the input file are considered words. If you have multiple words in a paragraph, they will each be separate in the Words collection.

So: In Interop.Word, a paragraph is made up of a collection of one or more words.

Quit. Why is the application.Quit statement important? If you don’t include this, the WINWORD.EXE application will remain in the process list. Then, when this program is run again, a new one will be started. This wastes memory.

Note: It is important to iterate on Words from 1 to Count inclusive. Correction suggested by Robert Ford.

Summary. We looked at the Microsoft.Office Interop.Word assembly and learned how to read in data from a Word document. This can be useful when you have DOC or DOCX files and want to programmatically read in data from your C# program.
