C# 代理访问页面并获取数据

本来在找IWebDriver使用代理的方法，偶然获知这种的，记录并且共享

 1 WebProxy proxyObject = new WebProxy("125.31.19.26", 80);//str为IP地址 port为端口号 代理类
 2 HttpWebRequest Req = (HttpWebRequest)WebRequest.Create("http://ip.chemdrug.com/"); // 61.183.192.5
 5 Req.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; QQWubi 133; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; CIBA; InfoPath.2)";
 6 Req.Proxy = proxyObject; //设置代理 
 8 Req.Method = "GET";
 9 HttpWebResponse Resp = (HttpWebResponse)Req.GetResponse();
10 string StringSub = "";
11 string OkStr = "";
12 Encoding code = Encoding.GetEncoding("gb2312");
13 using (StreamReader sr = new StreamReader(Resp.GetResponseStream(), code))
14 {
16    string str1 = sr.ReadToEnd();//获取得到的网址html返回数据，这里就可以使用某些解析html的dll直接使用了,比如htmlpaser
