page页面的部分div内容导出word(收藏)

protected void Button2_Click(object sender, EventArgs e)
        {
            
            System.IO.StringWriter SW = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter HTW = new System.Web.UI.HtmlTextWriter(SW);
            Page.EnableViewState = false;  
            Page.Form.RenderControl(HTW);
            //Page为要导出的对象,当前是Page,如果是DataGrid,DataList等都可以
            string pageHtml = SW.ToString();
            string pageHtml = ReplaceText(filecontent, getmodel());
            int startIndex = pageHtml.IndexOf("<div  id=\"PrintA\">");
            int endIndex = pageHtml.LastIndexOf("</div>");
            int lenth = endIndex - startIndex;
            pageHtml = pageHtml.Substring(startIndex, lenth);
            pageHtml = pageHtml.Replace("../images/1.jpg", Server.MapPath("../images/1.jpg"));  
            Response.Buffer = true;
            Response.Clear();
            Response.ClearContent();
            Response.ClearHeaders();
            Response.ContentType = "application/ms-word";
            //Response.ContentType是输出流的 HTTP MIME 类型
            //Response.ContentType      --- word文件
            //application/vnd.ms-excel --- excel文件
            Response.Charset = "utf-8";
            Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
            Response.AddHeader("Content-Disposition", "attachment;filename=" + xxxx + ".doc");
           // Response.AddHeader("content-length", file.Length.ToString());   
            //attachment --- 作为附件下载
            //inline --- 在线打开
            //filename如过是中文,则可以用HttpUtility.UrlEncode(fileName,System.Text.Encoding.UTF8)
            //进行进行编码,以解决文件名乱码的问题
            Response.Write(pageHtml.ToString());
            Response.Flush();
            Response.Close();

        }

用Uri MyUrl = Request.UrlReferrer;获取到客户端看到的地址和端口等解决图片问题
