Response.Write ("Response.Write ("</body>Here the file name is encoded to prevent the occurrence of Chinese name garbled phenomenon
Httpcontext.current.response.appendheader ("Content-disposition", "attachment;filename=" + Httputility.urlencode) (" File name. xls ", Encoding.UTF8));

Divid.page.enableviewstate = false;
System.IO.StringWriter tw = new System.IO.StringWriter ();
HtmlTextWriter HW = new HtmlTextWriter (TW);
Divid.rendercontrol (HW);
The bottom three lines are the output of the data.
Response.Write ("Httpcontext.current.response.write (Tw.tostring ());
Response.Write ("</body>

Response.Flush ();
Response.close ();
}
