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 < this.dataGridView1.ColumnCount; i++)
            {
                worksheet.Cells[1, i + 1] = this.dataGridView1.Columns[i].HeaderText;
            }
            //写入数值
            for (int r = 0; r < this.dataGridView1.Rows.Count; r++)
            {
                for (int i = 0; i < this.dataGridView1.ColumnCount; i++)
                {
                    worksheet.Cells[r + 2, i + 1] = this.dataGridView1.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)
                {
                    //fileSaved = false;
                    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("保存文件成功！");

for(int i=0;j<DataGridView1.RowCount;i++)
{
for(int j=0;j<DataGridView1.ColumnCount;j++)
{
 DataGridView[i,j].ToString();//读得出来就能打印了
}
}
