excel2007不能打开asp.net导出的excel
Response.Clear();Response.Buffer = true;
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode("test", Encoding.UTF8).ToString());
Response.ContentType = "application/ms-excel";
this.EnableViewState = false;
StringWriter tw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
GridView1.RenderControl(hw);
Response.Write(tw.ToString());
Response.End();
利用以上代码导出excel后，07版的打不开，提示：“**的格式与文件的扩展名指定的格式不一致.........”
