// Creates an HttpWebRequest with the specified URL. 
            HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url); 
            // Sends the HttpWebRequest and waits for the response.         
            HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse(); 
            // Gets the stream associated with the response.
            Stream receiveStream = myHttpWebResponse.GetResponseStream();
            Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
            // Pipes the stream to a higher level stream reader with the required encoding format. 
            StreamReader readStream = new StreamReader( receiveStream, encode );
Console.WriteLine("\r\nResponse stream received.");
            Char[] read = new Char[256];
              // Reads 256 characters at a time.    
            int count = readStream.Read( read, 0, 256 );
            Console.WriteLine("HTML...\r\n");
            while (count > 0) 
               {
                   // Dumps the 256 characters on a string and displays the string to the console.
                  String str = new String(read, 0, count);
                  Console.Write(str);
                  count = readStream.Read(read, 0, 256);
               }
            Console.WriteLine("");
            // Releases the resources of the response.
            myHttpWebResponse.Close();
            // Releases the resources of the Stream.
            readStream.Close();

StreamReader readStream = new StreamReader( receiveStream, encode );
string str = readStream.ReadToEnd();
