求WebRequest设定Proxy的写法

Question

RT：我目前的写法不管用public static void ProxySetting(HttpWebRequest request)
{
            WebProxy myProxy = new WebProxy();
            Uri newUri = new Uri("proxy.xxx.xxx:3128");
            myProxy.Address = newUri;
            request.Proxy = myProxy;
}

Answer 1

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(url);
WebProxy myProxy = new WebProxy("10.214.45.28:8080", true);
myProxy.Credentials = new NetworkCredential("id", "password");
req.Proxy = myProxy;

Answer 2

myProxy.Credentials = new NetworkCredential("id", "password");
这是什么意思？

string url = "";   
HttpWebRequest hwr = (HttpWebRequest)HttpWebRequest.Create(url);   
hwr.Timeout = 60000;   
WebProxy proxy = new WebProxy();   
proxy.Address = new Uri("");   
proxy.Credentials = new NetworkCredential("", "");   
hwr.UseDefaultCredentials = true;   
hwr.Proxy = proxy; 或 System.Net.WebRequest.GetSystemWebProxy();HttpWebResponse req= (HttpWebResponse)hwr.GetResponse();   
Stream s = req.GetResponseStream();   
StreamReader sr = new StreamReader(s, Encoding.UTF8);
