Answer 1

You need to write the file as binary, either use TransmitFile or BinaryWrite method, just using HtmlTextWriter will not help.

This might help!

        Response.Buffer = true;
        Response.ContentType = "application/text";
        Response.AppendHeader("Content-Disposition", "attachment; filename=file1.xls");
        Response.TransmitFile(fileName);
        Response.Flush();
        Response.End();

使用Response.Write而不是Response.Output.Write。
