添加數據到excel數據透視表代碼

Question

我有一些透視表的excel文件。 現在我需要將代碼添加到數據透視表源代碼中。 任何人都可以指導我如何做到這一點。

Answer 1

最後我得到了一個解決方案。 問題是使用波紋管代碼解決

public class PivotSheetProp 
    { 
     public int ID { get; set; } 
     public string SheetName { get; set; } 
     public int StartColumnIndex { get; set; } 
     public int StartRowIndex { get; set; } 
    } 

    public static void ReadExistingExcel(DataSet ds, List<PivotSheetProp> accPivotList, string path) 
    { 
     Microsoft.Office.Interop.Excel.Application oXL; 
     Microsoft.Office.Interop.Excel.Workbook mWorkBook; 
     Microsoft.Office.Interop.Excel.Sheets mWorkSheets; 
     Microsoft.Office.Interop.Excel.Worksheet mWSheet1; 

     oXL = new Microsoft.Office.Interop.Excel.Application(); 
     oXL.Visible = false; 
     oXL.DisplayAlerts = false; 
     mWorkBook = oXL.Workbooks.Open(path, 0, false, 5, "", "", false, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "", true, false, 0, true, false, false); 
     try 
     { 
      //Get all the sheets in the workbook 
      mWorkSheets = mWorkBook.Worksheets; 
      int tblCount = 0; 
      foreach (var v in accPivotList) 
      { 
       //Get the allready exists sheet 
       mWSheet1 = (Microsoft.Office.Interop.Excel.Worksheet)mWorkSheets.get_Item(v.SheetName); 

       //Set alignment and font size 
       mWSheet1.Cells.HorizontalAlignment = XlHAlign.xlHAlignCenter; 
       mWSheet1.Cells.VerticalAlignment = XlVAlign.xlVAlignCenter; 
       mWSheet1.Cells.Font.Size = 11; 

       Microsoft.Office.Interop.Excel.Range range = mWSheet1.UsedRange; 
       int colCount = range.Columns.Count; 
       int rowCount = range.Rows.Count; 
       int startRowCount = v.StartRowIndex; 
       if (startRowCount != 0) 
       { 
        rowCount = startRowCount; 
       } 
       for (int index = 1; index <= ds.Tables[tblCount].Rows.Count; index++) 
       { 
        int cellIndex = v.StartColumnIndex; 
        foreach (object tc in ds.Tables[tblCount].Rows[index - 1].ItemArray) 
        { 
         mWSheet1.Cells[rowCount + index, cellIndex++] = tc.ToString(); 
        } 
       } 

       tblCount++; 
      } 

      foreach (Microsoft.Office.Interop.Excel.Worksheet pivotSheet in mWorkSheets)

       int pivotTablesCount = pivotTables.Count; 
       if (pivotTablesCount > 0) 
       { 
        for (int i = 1; i <= pivotTablesCount; i++) 
        { 
         pivotTables.Item(i).RefreshTable(); //The Item method throws an exception 
        } 
       }

     catch (Exception ex)
