这个在asp的时候我是这么做的,但是在asp.net中，还是推荐用现成的对象好,比如

HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + filename);
HttpContext.Current.Response.Charset = "UTF-8";
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default;
HttpContext.Current.Response.ContentType = filetype;

//HttpContext.Current.Response.ContentType = "application/ms-excel";//image/JPEG;text/HTML;image/GIF;vnd.ms-excel/msword

System.IO.StringWriter tw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
gv.RenderControl(hw);

HttpContext.Current.Response.Write(tw.ToString());
HttpContext.Current.Response.End();  回复

是的,我也是用现成的,这就是上面我说的,我经常导出EXCEL,那个函数我写在了
Table导出为xls,doc,txt,htm方法
但如果导出WORD,就会出现编码的问题,当添了上面那段,问题就解决了:)
