C#做的通过http读取一个网页的内容的程序,请问如果用代理,怎么做呢?不用代理的代码是这样写的,改用用代理的该怎么写呢?我自己写了下,不成功.
  private void SendRequestData(string URL, string method, bool showProgress)
        {
            clientSocket = new TcpClient();
            Uri URI = new Uri(URL);
            clientSocket.Connect(URI.Host, URI.Port);            /***********可以用代理的,这种试式不成功***********/
            //clientSocket = new TcpClient();
            //Uri URI;
            //WebProxy proxy = WebProxy.GetDefaultProxy();//获取IE缺省设置
            ////BasicHttpBinding binding = new BasicHttpBinding();
            //if (proxy.Address != null)//== null && binding.ProxyAddress != null
            //    URI = proxy.Address;
            //else
            //    URI = new Uri(URL);
            //clientSocket.Connect(URI.Host, URI.Port);
            /***************************/
            requestHeaders.Add("Host", URI.Host);
            byte[] request = GetRequestHeaders(method + " " + URI.PathAndQuery + " HTTP/1.1");
            clientSocket.Client.Send(request);
            //..........
