public void setToExcel()
{
//            Response.Clear();
//            Response.Buffer= true;

    if (eformsn.Text=="")
    {
        DataGrid1.Visible=false;
        Label1.Text="要匯入EXCEL，請先輸入申請單號!";
        Label1.Visible=true;

    {
        dl.DataSource=DB("query", "select * from msi_eol_list_line where eformsn="+eformsn.Text+" order by eformsn").Tables[0].DefaultView;
        dl.DataBind();

        //下面這行很重要，attachment 參數表示做為附件下載，您能夠改爲online在線打開
        //filename= http://www.xzqdds.com  ).xls 指定輸出文件的名稱，注意其擴展名和指定文件類型相符，能夠為：.doc  .xls  .txt  .htm

        Response.AppendHeader("Content-Disposition","attachment;filename=EOL_"+eformsn.Text+".xls");
        Response.ContentEncoding=System.Text.Encoding.GetEncoding("utf-8");

        //Response.ContentType指定文件類型 能夠為application/ms-excel,application/ms-word ,application/ms-txt,application/ms-html或其餘瀏覽器可直接支持文檔
        Response.ContentType = "application/ms-excel";
        dl.EnableViewState = false;

        System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

        //將目 淘寶熱賣標數據綁定到輸入流輸出
        //this 表示輸出本頁，你也能夠綁定datagrid,或其餘支持obj.RenderControl()屬性的控件
        // http://www.89900.com  
        dl.RenderControl(oHtmlTextWriter);
        //this.DataBind.RenderControl(oHtmlTextWriter);
        Response.Write(oStringWriter.ToString());
        Response.End();
