问题描述

当我运行导出到Excel"时，Spreadheet包含数据，但是如果我通过邮件发送，则该数据将为空.有人知道这可能是什么原因吗?
代码是:

When I run my Export to Excel, the Spreadheet contains data but if i send it via mail it becomes empty. Anyone know what may cause this?
the code is :

string attachment = "attachment; filename=att_Data.xls";
Response.ClearContent();
Response.AddHeader("content-disposition", attachment);
Response.ContentType = "application/ms-excel";

StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
GridView1.RenderControl(htw);
Response.Write("<meta http-equiv=\"Content-Type\" content=\"text/html;       charset=utf-8\" />");
Response.Write(sw.ToString());
Response.End();

推荐答案

//Stopwatch sw1 = Stopwatch.StartNew();//1.85
        ////#region "Downloading excel file with Certificate Track data "
        //System.IO.StringWriter tw = new System.IO.StringWriter();
        //System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
        //DataGrid dgGrid = new DataGrid();
        //dgGrid.DataSource = objDataTable;
        //dgGrid.DataBind();
        ////Get the HTML for the control.
        //dgGrid.RenderControl(hw);
        //HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
        //HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName + ".xlsx");
        ////this.EnableViewState = false;
        //HttpContext.Current.Response.Write(tw.ToString());
        //sw1.Stop();
        //TimeSpan elapsed = sw1.Elapsed;
        //HttpContext.Current.Response.End();
        //System.Diagnostics.Process.Start(finalFileNameWithPath);
