添加一个类文件makefile：

#region 根据绝对url生成Htm页面
    public bool makeUrlhtm(string pageUrl, string filePath, string fileName,string basepath)
    {
        string filePage = HttpContext.Current.Server.MapPath(filePath + fileName);

        StreamWriter sw = null;
        //获得静态html
        try
        {
            if (!Directory.Exists(HttpContext.Current.Server.MapPath(filePath)))
            {
                Directory.CreateDirectory(HttpContext.Current.Server.MapPath(filePath));
            }
            if (File.Exists(filePage))
            {
                File.Delete(filePage);
            }
            sw = new StreamWriter(filePage, false, Encoding.GetEncoding("GB2312"));
            WebRequest wReq = WebRequest.Create(pageUrl);
            WebResponse wResp = wReq.GetResponse();
            Stream respStream = wResp.GetResponseStream();
            StreamReader reader = new StreamReader(respStream, Encoding.GetEncoding("gb2312"));
            string finalHtml = reader.ReadToEnd();
            finalHtml = ClearInput(finalHtml);
            //string basepath = "<base href='http://www.cupledu.com/StudyCenter/FsJobgrinds/' /><meta http-equiv='Content-Type' content='text/html; charset=utf-8' />";
            if (finalHtml.IndexOf(@"<head>")>0)
            {
                finalHtml.Insert(finalHtml.IndexOf(@"<head>")+6,basepath);
            }
            sw.Write(finalHtml);
            //HttpContext.Current.Response.Write("<script language='JavaScript'>alert('生成成功！');</script>");
            return true;
        }
        catch
        {
            //HttpContext.Current.Response.Write("<script language='JavaScript'>alert('生成失败！');</script>");
            return false;//生成到出错
        }
        finally
        {
            sw.Flush();
            sw.Close();
            sw = null;
        }

}
#endregion

#region ClearInput
    public string ClearInput(string finalHtml)
    {
        string pattern = @"<input type=""hidden"" name=""__VIEWSTATE""[^>]*>";//清除hidden内容
        string pattern1 = @"<input type=""hidden"" name=""__EVENTVALIDATION""[^>]*>";//清除hidden内容
        string FormTargetBegin = @"<form name=[^>]*>";//清除Form
        string FormTargetEnd = @"</form>";

//取得匹配值
string s = ((System.Text.RegularExpressions.Capture)(Regex.Match(finalHtml, pattern).Groups.SyncRoot)).Value;

        finalHtml = Regex.Replace(finalHtml, pattern, string.Empty, RegexOptions.IgnoreCase | RegexOptions.Multiline);
        finalHtml = Regex.Replace(finalHtml, pattern1, string.Empty, RegexOptions.IgnoreCase | RegexOptions.Multiline);
        finalHtml = Regex.Replace(finalHtml, FormTargetBegin, string.Empty, RegexOptions.IgnoreCase | RegexOptions.Multiline);
        finalHtml = Regex.Replace(finalHtml, FormTargetEnd, string.Empty, RegexOptions.IgnoreCase | RegexOptions.Multiline);
        return finalHtml;
    }
    #endregion

调用：

makeFile function = new makeFile();
            string url = "要下载的页面路径如www.baidu.com";
            string severpath = Server.MapPath("~/");
            string basepath = "<base href='http://www.cupledu.com/StudyCenter/FsJobgrinds/' /><meta http-equiv='Content-Type' content='text/html; charset=utf-8' />";
            function.makeUrlhtm(url, searpath, "zfindex.html", basepath);
