用的这段导出到Excel的代码：

1. /// <summary>
   
2.         /// 将结果集导出到Excel
   
3.         /// </summary>
   
4.         /// <param name="dsControl">数据源控件</param>
   
5.         /// <param name="strFileName">导出的文件名</param>
   
6.         private void ExportExcel(ref System.Web.UI.WebControls.ListView dsControl, string strFileName)
   
7.         {
   
8.             strFileName = System.Web.HttpUtility.UrlEncode(strFileName, System.Text.Encoding.UTF8);
   
9. 
   
10.             System.Web.HttpContext.Current.Response.Clear();
    
11.             System.Web.HttpContext.Current.Response.Buffer = true;
    
12.             System.Web.HttpContext.Current.Response.Charset = "utf-8";
    
13.             System.Web.HttpContext.Current.Response.AppendHeader("Content-Disposition", "online; filename=" + strFileName + ".xls");
    
14.             System.Web.HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");
    
15.             System.Web.HttpContext.Current.Response.ContentType = "application/ms-excel";
    
16. 
    
17.             System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("zh-CN", true);
    
18.             System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);
    
19.             System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
    
20. 
    
21.             dsControl.RenderControl(oHtmlTextWriter);
    
22. 
    
23.             dsControl = null;
    
24.             System.Web.HttpContext.Current.Response.Write(oStringWriter.ToString().Replace("<td", "<td STYLE='MSO-NUMBER-FORMAT:\\@'"));
    
25.             System.Web.HttpContext.Current.Response.Buffer = false;
    
26.             System.Web.HttpContext.Current.Response.End();
    
27.         }

我是想将ListView里边的内容导出来，终于导出来Excel了，结果打开的时候提示：



请问是怎么回事？
然后打开发现，把按钮、css样式等也给导出来了




我想去除css样式，比如表头的“姓名”的背景色，
还有 “编辑”、“删除”等按钮。
请问该怎么写？

protected void ExportExcel(object sender, EventArgs e)
{
        Response.Clear();
        Response.Buffer = false;
        Response.Charset = "GB2312";
        Response.AppendHeader("Content-Disposition", "attachment;filename="+HttpUtility.UrlEncode(DropListReport.SelectedValue, System.Text.Encoding.UTF8).ToString());
        Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
        Response.ContentType = "application/ms-excel";
        Response.Write("<meta http-equiv=Content-Type content=\"text/html; charset=GB2312\">");
        this.EnableViewState = false;

        System.IO.StringWriter stringWrite = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);

        GridViewResule.AllowPaging = false;
        ShowData((Template)Session["TemplateFile"]);

        GridViewResule.RenderControl(htmlWrite);
        Response.Write(stringWrite.ToString());
        Response.End();
        GridViewResule.AllowPaging = true;
}
