C# http 访问Ip地址

 HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.example.com/Default.aspx");            System.Net.WebProxy proxy = new WebProxy("10.0.0.28", 8080);            request.Proxy = proxy;            using (WebResponse response = request.GetResponse())            {                using (TextReader reader = new StreamReader(response.GetResponseStream()))                {                    string line;                    while ((line = reader.ReadLine()) != null)                        Console.WriteLine(line);                }            }
