MS DataGrid导出Excel

说明：代码是模仿同行的，首先感谢这位同行提高部分代码支持，自己只是调用。。。但是在实际操作中会出现Excel版本不兼容的问题，在第一次打开导出的Excel表是可能会报错，没关系，请看下面：private void bt_OutData_Click(object sender, EventArgs e){string fileName = "";DataToExcel pDataToExcel = new DataToExcel();pDataToExcel.ExportExcel(fileName, dtg_PointOnly);}

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Windows.Forms;using System.IO;using System.Security.AccessControl;namespace ZYPipeJianLi.Class{internal class DataToExcel{public  void ExportExcel(string fileName, DataGridView myDGV){if (myDGV.Rows.Count > 0){string saveFileName = "";SaveFileDialog saveDialog = new SaveFileDialog();saveDialog.DefaultExt = "xlsx";saveDialog.Filter = "Excel文件|*.xlsx";//报错有可能就是这里的问题，注意尾缀和版本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PC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 (saveFileName != ""){try{workbook.Saved = true;workbook.SaveCopyAs(saveFileName);//fileSaved = true;}catch (Exception ex){MessageBox.Show("导出文件时出错,文件可能正被打开！\n" + ex.Message);}}xlApp.Quit();GC.Collect();//强行销毁MessageBox.Show(fileName + "数据导出成功！", "提示", MessageBoxButtons.OK);}else{MessageBox.Show("报表为空,无表格需要导出！", "提示", MessageBoxButtons.OK);}}}}

在导出的时候要注意excel的版本，部分修改文件的尾缀，就可以解决导出第一次打开报错的问题！再次感谢同行代码支持！
