通过代理时连接超时

Question

This code works perfectly when not going through a proxy server. it loads the required webpage. When i uncomment one line I get an error.

Error message

 "The underlying connection was closed: The connection was closed unexpectedly." System.Exception System.Net.WebException 

The one line that causes the error.

//request.Proxy = new Webproxy("192.157.252.245",80);

The proxy I am using works fine when going through a proxy website or setting it as local proxy.

Uri address = new Uri("http://google.com/");
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(address);

request.Method = "GET";
request.ContentType = "application/x-www-form-urlencoded";

////////Add Proxy
//request.Proxy = new Webproxy("192.157.252.245",80);
////////End Add Proxy

using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
    StreamReader streamReader = new StreamReader(response.GetResponseStream());
    string strReaderXML = streamReader.ReadToEnd();
}
