Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.ContentType = "application/ms-excel ";//设置输出文件类型为excel文件。
System.IO.StringWriter ostringwriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter ohtmltextwriter = new System.Web.UI.HtmlTextWriter(ostringwriter);

this.GridView1.RenderControl(ohtmltextwriter);

< <这一句报错> > 类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内。

Response.Output.Write(ostringwriter.ToString());
Response.Flush();
Response.End();
