C# WinForm下DataGridView导出Excel的实现(简单无错版,带另存对话框)
//首先请先引用:Microsoft.Office.Interop.Excel 11.0.0.0 . #region 导出excel private void ExportExcel(string fileName, DataGridView myDGV) { string saveFileName = ""; //bool fileSaved = false; SaveFileDialog saveDialog = new SaveFileDialog(); saveDialog.DefaultExt = "xls"; saveDialog.Filter = "Excel文件|*.xls"; saveDialog.FileName = fileName; saveDialog.ShowDialog(); saveFileName = saveDialog.FileName; if (saveFileName.IndexOf(":") < 0) return; //被点了取消 Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application(); if (xlApp == null) { MessageBox.Show("无法创建Excel对象,可能您的机子未安装Excel"); return; } Microsoft.Office.Interop.Excel.Workbooks workbooks = xlApp.Workbooks; Microsoft.Office.Interop.Excel.Workbook workbook = workbooks.Add(Microsoft.Office.Interop.Excel.XlWBATemplate.xlWBATWorksheet); Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets[1];//取得sheet1 //写入标题 for (int i = 0; i < myDGV.ColumnCount; i++) { worksheet.Cells[1, i + 1] = myDGV.Columns[i].HeaderText; } //写入数值 for (int r = 0; r < myDGV.Rows.Count; r++) { for (int i = 0; i < myDGV.ColumnCount; i++) { worksheet.Cells[r + 2, i + 1] = myDGV.Rows[r].Cells[i].Value; } System.Windows.Forms.Application.DoEvents(); } worksheet.Columns.EntireColumn.AutoFit();//列宽自适应 //if (Microsoft.Office.Interop.cmbxType.Text != "Notification") //{ // Excel.Range rg = worksheet.get_Range(worksheet.Cells[2, 2], worksheet.Cells[ds.Tables[0].Rows.Count + 1, 2]); // rg.NumberFormat = "00000000"; //} if (saveFileName != "") { try { workbook.Saved = true; workbook.SaveCopyAs(saveFileName); //fileSaved = true; } catch (Exception ex) { //fileSaved = false; MessageBox.Show("导出文件时出错,文件可能正被打开!\n" + ex.Message); } } //else //{ // fileSaved = false; //} xlApp.Quit(); GC.Collect();//强行销毁 // if (fileSaved && System.IO.File.Exists(saveFileName)) System.Diagnostics.Process.Start(saveFileName); //打开EXCEL MessageBox.Show(fileName + "的简明资料保存成功", "提示", MessageBoxButtons.OK); } #endregion
