增量工作表會計算出您可以在單個Excel文件中保存多個數據集值。

希望它對你有幫助。

之前u必須創建
1.使用的Excel =的Microsoft.Office.Interop.Excel;在報頭//，以及添加正確REFFERENCE
2.Excel.Application excelHandle1 = PrepareForExport（DS）; //在調用函數中添加句柄 excelHandle1.Visible = true;

public Excel.Application PrepareForExport(System.Data.DataSet ds,string[] sheet) 
    { 
      object missing = System.Reflection.Missing.Value; 
      Excel.Application excel = new Excel.Application(); 
      Excel.Workbook workbook = excel.Workbooks.Add(missing); 

      DataTable dt1 = new DataTable(); 
      dt1 = ds.Tables[0]; 
      DataTable dt2 = new DataTable(); 
      dt2 = ds.Tables[1]; 


      Excel.Worksheet newWorksheet; 
      newWorksheet = (Excel.Worksheet)excel.Worksheets.Add(missing, missing, missing, missing); 
      newWorksheet.Name ="Name of data sheet"; 

// for first datatable dt1.. 

      int iCol1 = 0; 
      foreach (DataColumn c in dt1.Columns) 
      { 
       iCol1++; 
       excel.Cells[1, iCol1] = c.ColumnName; 
      } 

      int iRow1 = 0; 
      foreach (DataRow r in dt1.Rows) 
      { 
       iRow1++; 

       for (int i = 1; i < dt1.Columns.Count + 1; i++) 
       { 

        if (iRow1 == 1) 
        { 
         // Add the header the first time through 
         excel.Cells[iRow1, i] = dt1.Columns[i - 1].ColumnName; 
        } 

        excel.Cells[iRow1 + 1, i] = r[i - 1].ToString(); 
       } 

      } 

    // for second datatable dt2.. 

      int iCol2 = 0; 
      foreach (DataColumn c in dt2.Columns) 
      { 
       iCol2++; 
       excel.Cells[1, iCol] = c.ColumnName; 
      } 


      int iRow2 = 0; 
      foreach (DataRow r in dt2.Rows) 
      { 
       iRow2++; 

       for (int i = 1; i < dt2.Columns.Count + 1; i++) 
       { 

        if (iRow2 == 1) 
        { 
         // Add the header the first time through 
         excel.Cells[iRow2, i] = dt2.Columns[i - 1].ColumnName; 
        } 

        excel.Cells[iRow2 + 1, i] = r[i - 1].ToString(); 
       } 

      } 




     return excel; 
    }
