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！
