ASP.NET导出页面内容至word文档

前台页面需要添加属性：EnableEventValidation="false"

导出事件主要代码:  

[csharp] view plaincopyprint?

1. protected void btnImportPage_Click(object sender, EventArgs e)  
2.        {  
3.            //设置Http的头信息,编码格式  
4.            HttpContext.Current.Response.Buffer = true;  
5.            HttpContext.Current.Response.Clear();  
6.            HttpContext.Current.Response.ClearContent();  
7.            HttpContext.Current.Response.ClearHeaders();  
8.   
9.            HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode("行政管理制度.doc", System.Text.Encoding.UTF8));  
10.            HttpContext.Current.Response.ContentType = "application/ms-word";  
11.   
12.            HttpContext.Current.Response.Charset = "UTF-8";  
13.            HttpContext.Current.Response.HeaderEncoding = System.Text.Encoding.UTF8;  
14.            HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;  
15.            //关闭控件的视图状态  
16.            Page.EnableViewState = false;  
17.            //初始化HtmlWriter  
18.            System.IO.StringWriter writer = new System.IO.StringWriter();  
19.            System.Web.UI.HtmlTextWriter htmlWriter = new System.Web.UI.HtmlTextWriter(writer);  
20.            Page.RenderControl(htmlWriter);  
21.            //输出  
22.            string pageHtml = writer.ToString();  
23.            int startIndex = pageHtml.IndexOf("<div style=\"margin: 0 auto;\" id=\"mainContent\">");  
24.            int endIndex = pageHtml.LastIndexOf("</div>");  
25.            int lenth = endIndex - startIndex;  
26.            pageHtml = pageHtml.Substring(startIndex, lenth);  
27.            pageHtml = pageHtml.Remove(pageHtml.LastIndexOf("<div class=\"flowbar\">"));  
28.            //设置图片路径  
29.            Uri MyUrl = Request.UrlReferrer;  
30.            pageHtml = pageHtml.Replace("../Images/", "http://" + MyUrl.Authority + "/Images/").Replace("textarea", "span");     
31.            HttpContext.Current.Response.Write(pageHtml.ToString());  
32.            HttpContext.Current.Response.End();  
33.        }
