    生成EXCEL文件#region 生成EXCEL文件public void setToExcel(){//            Response.Clear(); //            Response.Buffer= true; //            Response.Charset="utf-8";          if (eformsn.Text=="")    {        DataGrid1.Visible=false;        Label1.Text="要匯入EXCEL,請先輸入申請單號!";        Label1.Visible=true;    }    else    {        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 參數表示作為附件下載,您可以改成online在線打開         //filename=FileFlow.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,可以為:.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 可以為application/ms-excel,application/ms-word ,application/ms-txt,application/ms-html或其他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);

            //將目標數據綁定到輸入流輸出           //this 表示輸出本頁,你也可以綁定datagrid,或其他支持obj.RenderControl()屬性的控件           dl.RenderControl(oHtmlTextWriter);        //this.DataBind.RenderControl(oHtmlTextWriter);         Response.Write(oStringWriter.ToString());         Response.End();     }}#endregion
