// 代理服务器(产品官网 )
string proxyHost = "";
string proxyPort = "31111";

// 代理验证信息
string proxyUser = "username";
string proxyPass = "password";

// 设置代理服务器
WebProxy proxy = new WebProxy(string.Format("{0}:{1}", proxyHost, proxyPort), true);

request.Method = "GET";
request.Proxy = proxy;

//request.Proxy.Credentials = CredentialCache.DefaultCredentials;

request.Proxy.Credentials = new System.Net.NetworkCredential(proxyUser, proxyPass);

// 设置Proxy Tunnel
// Random ran=new Random();
// int tunnel =ran.Next(1,10000);
