将数据从表单上的多个DataGridViews导出到单个Excel文件中的多个Excel表格
我有一个数据库应用程序，它在Form上有多个dataGridViews 。 我能够成功地将一个网格视图导出到Excel工作表，但是我想将网格导出到单个Excel文件中的不同Excel工作表。
我尝试了以下哪些不起作用。
public void ExportGridViewToExcel(DataGridView dataGridViewCommission, DataGridView dataGridViewPaymentsReceived, string commissionsheet, string paymentsheet) { // creating Excel Application Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application(); // creating new WorkBook within Excel application Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing); // creating new Excelsheet in workbook Microsoft.Office.Interop.Excel._Worksheet worksheet1 = null; Microsoft.Office.Interop.Excel._Worksheet worksheet2 = null; // see the excel sheet behind the program // app.Visible = true; // get the reference of first sheet. By default its name is Sheet1. // store its reference to worksheet worksheet1 = workbook.Sheets[1]; // changing the name of active sheet worksheet1.Name = commissionsheet; string filelocation; SaveFileDialog SaveFile = new SaveFileDialog(); if (SaveFile.ShowDialog() == DialogResult.OK) { filelocation = SaveFile.FileName; // storing header part in Excel for (int i = 1; i < dataGridViewCommission.Columns.Count + 1; i++) { worksheet1.Cells[1, i + 1] = dataGridViewCommission.Columns[i - 1].HeaderCell.Value; } for (int i = 1; i < dataGridViewCommission.Rows.Count + 1; i++) { worksheet1.Cells[i + 1, 1] = dataGridViewCommission.Rows[i - 1].HeaderCell.Value; //worksheet2.Cells[i + 1, 1] = dataGridViewPaymentsReceived.Rows[i - 1].HeaderCell.Value; } for (int i = 0; i < dataGridViewCommission.Rows.Count; i++) { for (int j = 0; j < dataGridViewCommission.Columns.Count; j++) { worksheet1.Cells[i + 2, j + 2] = dataGridViewCommission.Rows[i].Cells[j].Value.ToString(); } } worksheet2 = workbook.Sheets["Sheet2"]; worksheet2.Name = paymentsheet; for (int i = 1; i < dataGridViewPaymentsReceived.Columns.Count + 1; i++) { worksheet2.Cells[1, i + 1] = dataGridViewPaymentsReceived.Columns[i - 1].HeaderCell.Value; } // storing Each row and column value to excel sheet for (int i = 0; i < dataGridViewPaymentsReceived.Rows.Count; i++) { for (int j = 0; j < dataGridViewPaymentsReceived.Columns.Count; j++) { worksheet2.Cells[i + 2, j + 2] = dataGridViewPaymentsReceived.Rows[i].Cells[j].Value.ToString(); } } // save the application workbook.SaveAs(filelocation, 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); app.Quit(); Process.Start(filelocation + ".xls"); } }
我遇到了一个COMexception ，无效索引。 （从HRESULTexception：0x8002000B（DISP_E_BADINDEX））
任何人都可以build议我摆脱这种方式吗？
也许你需要添加更多的工作表，然后才能访问索引2的工作表
int count = workbook.Worksheets.Count; Excel.Worksheet addedSheet = workbook.Worksheets.Add(Type.Missing, workbook.Worksheets[count], Type.Missing, Type.Missing);
