将数据插入到单个Excel工作簿上的多个工作表中

我正在从两个不同的C＃列表导出到一个工作簿中的两个Excel工作表使用下面的代码

Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application(); Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing); Microsoft.Office.Interop.Excel._Worksheet worksheet1 = null; worksheet1 = (Microsoft.Office.Interop.Excel._Worksheet)workbook.Sheets["Sheet1"]; worksheet1 = (Microsoft.Office.Interop.Excel._Worksheet)workbook.ActiveSheet; for (int i = 1; i < listExport.Count + 1; i++) { worksheet1.Cells[i+1,1] = listExport[i - 1].time.ToString("HH:mm:ss"); worksheet1.Cells[i+1, 2] = listExport[i - 1].CC; worksheet1.Cells[i+1, 3] = listExport[i - 1].term; } Microsoft.Office.Interop.Excel._Worksheet worksheet2 = null; worksheet2 = (Microsoft.Office.Interop.Excel._Worksheet)workbook.Sheets["Sheet2"]; worksheet2 = (Microsoft.Office.Interop.Excel._Worksheet)workbook.ActiveSheet; for (int i = 1; i < AxiomSubSet.Count + 1; i++) { worksheet2.Cells[i + 1, 1] = AxiomSubset[i - 1].time.ToString("HH:mm:ss"); worksheet2.Cells[i + 1, 2] = AxiomSubset[i - 1].CC; } string fileDestination = @"S:\Axiom Derivatives\Parser Project\axiom.xls"; if (File.Exists(fileDestination)) { File.Delete(fileDestination); } workbook.SaveAs(fileDestination, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing); workbook.Close(true, Type.Missing, Type.Missing); Process.Start(fileDestination); app.Quit(); 

但是，当我运行上面的方法第一个列表已成功处理，但是当分配第二个工作表在下面的行它扔我错误Invalid index. (Exception from HRESULT: 0x8002000B (DISP_E_BADINDEX)) Invalid index. (Exception from HRESULT: 0x8002000B (DISP_E_BADINDEX))

worksheet2 ==Microsoft.Office.Interop.Excel._Worksheet)workbook.Sheets["Sheet2"];

这不是处理多个Excel工作表的方法吗？

Answer 1

第二个工作表可能不称为Sheet2。 最好只是使用索引。

另外，您需要调用“激活”以使工作表2成为活动工作表：

在第一张纸之前

 worksheet1 = (Microsoft.Office.Interop.Excel._Worksheet)workbook.Sheets[1]; workbook.Sheets[1].Activate(); 

在第二张之前

  worksheet2 = (Microsoft.Office.Interop.Excel._Worksheet)workbook.Sheets[2]; workbook.Sheets[2].Activate();
