如何把label里有html格式的文字导出到一个word文档里,word里的文字要有label里的html格式        public static void tofiles(System.Web.HttpResponse pa, System.Web.UI.WebControls.Label Label, string filename, string filetype)
        {
            System.Web.HttpResponse httpresponse = pa;            httpresponse.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");
            if (filetype == "0")
            {
                httpresponse.AppendHeader("content-disposition", "attachment;filename=" + HttpUtility.UrlEncode(filename, System.Text.Encoding.UTF8) + ".doc"); //filename="*.doc"; 
                httpresponse.ContentType = "application/msword";
            }
            else
            {
                httpresponse.AppendHeader("content-disposition", "attachment;filename=" + HttpUtility.UrlEncode(filename, System.Text.Encoding.UTF8) + ".xls"); //filename="*xls";

            System.IO.StringWriter sw = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(sw);
            HttpUtility.HtmlEncode(Label.Text, hw);            //hw.Write(a);            httpresponse.Output.Write(HttpUtility.HtmlDecode(sw.ToString()));
            httpresponse.End();
        }
