WinFrom:DataGridView中多维表头如何导出到Excel

Question

DataGridView中多维表头如何导出到Excel

Answer 1

没搞过，DevExpress的表格控件有这个功能

Answer 2

DataGridView没试过，我以前Infragistics第三方控件可以public static void ExPort(string gridtextname, Infragistics.Win.UltraWinGrid.UltraGrid grid, Infragistics.Win.UltraWinGrid.ExcelExport.UltraGridExcelExporter exprot)
        {
            try
            {
                string exfilename = gridtextname;
                DialogResult rs = DialogResult.No;
                SaveFileDialog saved = new SaveFileDialog();
                saved.InitialDirectory = "d:\\";
                saved.DefaultExt = "*.xls";
                //saved.FileName = exfilename.Substring(0, exfilename.Length - 4);
                saved.FileName = exfilename;
                saved.Filter = "XLS Files|*.xls";
                saved.FilterIndex = 2;
                saved.RestoreDirectory = true;                if (saved.ShowDialog() == DialogResult.OK)
                {                    exfilename = saved.FileName;
                    DateTime start = DateTime.Now;
                    exprot.Export(grid, exfilename);
                    TimeSpan timeSpan = DateTime.Now - start;
                    rs = MessageBox.Show("数据导出操作成功，打开文件吗？ ", "提示信息 ", MessageBoxButtons.YesNo, MessageBoxIcon.Information);
                    if (rs == DialogResult.Yes)
                    {
                        System.Diagnostics.ProcessStartInfo st = new System.Diagnostics.ProcessStartInfo(exfilename);
                        st.WindowStyle = System.Diagnostics.ProcessWindowStyle.Minimized;
                        System.Diagnostics.Process.Start(st);
                    }
                }
            }
            catch (Exception ex)
            {
                Console.Write(ex.Message);
                MessageBox.Show(ex.ToString(), "提示信息", MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
        }

谢谢了，可现在就得用DataGridView

你的多维表头是怎么做的呀？我有个能导出到EXCEL的。不知道你原来的表头是如何生成的，所以搞不清楚这个方法对你有用没
