导出页面内容至word文档前台页面需要添加属性：EnableEventValidation="false"


	<span style="font-size: 12px;">protected void btnImportPage_Click(object sender, EventArgs e)</span>

	 {
	 //设置Http的头信息,编码格式
	 HttpContext.Current.Response.Buffer = true;
	 HttpContext.Current.Response.Clear();
	 HttpContext.Current.Response.ClearContent();
	 HttpContext.Current.Response.ClearHeaders();

	 HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode("行政管理制度.doc", System.Text.Encoding.UTF8));
	 HttpContext.Current.Response.ContentType = "application/ms-word";

	 HttpContext.Current.Response.Charset = "UTF-8";
	 HttpContext.Current.Response.HeaderEncoding = System.Text.Encoding.UTF8;
	 HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
	 //关闭控件的视图状态
	 Page.EnableViewState = false;
	 //初始化HtmlWriter
	 System.IO.StringWriter writer = new System.IO.StringWriter();
	 System.Web.UI.HtmlTextWriter htmlWriter = new System.Web.UI.HtmlTextWriter(writer);
	 Page.RenderControl(htmlWriter);
	 //输出
	 string pageHtml = writer.ToString();
	 int startIndex = pageHtml.IndexOf("<div style=\"margin: 0 auto;\" id=\"mainContent\">");
	 int endIndex = pageHtml.LastIndexOf("</div>");
	 int lenth = endIndex - startIndex;
	 pageHtml = pageHtml.Substring(startIndex, lenth);
	 pageHtml = pageHtml.Remove(pageHtml.LastIndexOf("<div class=\"flowbar\">"));
	 //设置图片路径
	 Uri MyUrl = Request.UrlReferrer;
	 pageHtml = pageHtml.Replace("../Images/", "http://" + MyUrl.Authority + "/Images/").Replace("textarea", "span");
	 HttpContext.Current.Response.Write(pageHtml.ToString());
	 HttpContext.Current.Response.End();
	 }
