У меня есть сценарий aС#, который успешно открывает указанную книгу Excel, удаляет первую строку и сохраняет ее как формат csv.

У меня проблема, что CSV сохраняет стандартную ширину столбца 8.43. Я хотел бы изменить ширину столбца col J как 17.00 перед сохранением csv.

Может кто-нибудь, пожалуйста, сообщите, как я установил ширину полки Col J до 17.

Из-за процесса я не могу использовать VBA/Macros.

Я использую;

myWorkSheet.Columns["J:J"].ColumnWidth = 17.57;

Однако это приводит к тому, что объект не содержит определения для скриншота «ColumnWidth».

Полный код ниже;

        public void DeleteRows(string OriginalFileName,String NewFileName)
    {
        Microsoft.Office.Interop.Excel.Application myApp;
        Microsoft.Office.Interop.Excel.Workbook myWorkBook;
        Microsoft.Office.Interop.Excel.Worksheet myWorkSheet;
        Microsoft.Office.Interop.Excel.Range range;
        myApp = new Microsoft.Office.Interop.Excel.Application();
        myWorkBook = myApp.Workbooks.Open(OriginalFileName, 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "t", false, false, 0, true, 1, 0);
        myWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)myWorkBook.Worksheets.get_Item(1);
        range = (Microsoft.Office.Interop.Excel.Range)myWorkSheet.Application.Rows[1, Type.Missing];
        range.Select();
        range.Delete(Microsoft.Office.Interop.Excel.XlDirection.xlUp);
        //Microsoft.Office.Interop.Excel.Range ThisRange1 = myWorkSheet.get_Range("J:J",System.Type.Missing);
        myWorkSheet.Columns["J:J"].ColumnWidth = 17.57; //ERRORLINE
        myApp.DisplayAlerts = false;
        myWorkSheet.SaveAs(NewFileName, Microsoft.Office.Interop.Excel.XlFileFormat.xlCSVWindows, Type.Missing, Type.Missing, false, false, false, XlSaveConflictResolution.xlLocalSessionChanges, Type.Missing, Type.Missing);
        myWorkBook.Close(false);
        myApp.Quit();
    }

Finally i get Solution……
