C#程序中设置全局代理(Global Proxy)

1. HttpWebRequest类的Proxy属性，只要设置了该属性就能够使用代理了,如下：

1             //设置代理
2         WebProxy WP = new WebProxy("41.76.44.76", 3128);
3             ICredentials jxCredt = new NetworkCredential("proxy_username", "proxy_password");
4             WP.Credentials = jxCredt;
5             
6             HttpWebRequest webreq = HttpWebRequest.Create(uri);
7             webreq.Proxy = WP;//将代理赋值给HttpWebRequest的Proxy属性
