【原创】 ASP.NET C# 远程获取WEB页源代码

try
        {
            //方法一
            HttpWebRequest webrq = WebRequest.Create("http://www.hiyours.com.cn/index.aspx") as HttpWebRequest;
            HttpWebResponse webrs = webrq.GetResponse() as HttpWebResponse;
            StreamReader sr = new StreamReader(webrs.GetResponseStream(), Encoding.GetEncoding("gb2312"));
            Localize1.Text = Server.HtmlEncode(Regex.Match(sr.ReadToEnd(), "<body[\\s\\S]*?</body>", RegexOptions.IgnoreCase).Value);

            //方法二
            using (WebClient client = new WebClient())
            {
                client.Headers.Set("User-Agent", "Microsoft Internet Explorer");//此句是关键
                Byte[] pageData = client.DownloadData("http://www.hiyours.com.cn/index.aspx");
                Localize1.Text = Server.HtmlEncode(Encoding.GetEncoding("gb2312").GetString(pageData));
            }

            //方法三 只能用于静态读取字符串
            using (StreamReader sr = new StreamReader(Server.MapPath("d.aspx"), Encoding.GetEncoding("gb2312"))) //模板页路径
            {
                Localize1.Text = Server.HtmlEncode(sr.ReadToEnd());
                sr.Close();
            }
        }
        catch
        {
            Response.Write("<Script>alert('读取文件错误')</Script>");
        }
