Answer 3

private static string SocketSendReceive(string server, int port) 
    {
        string request = "GET / HTTP/1.1\r\nHost: " + server + 
            "\r\nConnection: Close\r\n\r\n";
        Byte[] bytesSent = Encoding.ASCII.GetBytes(request);
        Byte[] bytesReceived = new Byte[256];
       
        // Create a socket connection with the specified server and port.
        Socket s = ConnectSocket(server, port);        if (s == null)
            return ("Connection failed");
      
        // Send request to the server.
        s.Send(bytesSent, bytesSent.Length, 0);  
        
        // Receive the server home page content.
        int bytes = 0;
        string page = "Default HTML page on " + server + ":\r\n";        // The following will block until te page is transmitted.
        do {
            bytes = s.Receive(bytesReceived, bytesReceived.Length, 0);
            page = page + Encoding.ASCII.GetString(bytesReceived, 0, bytes);
        }
        while (bytes > 0);
        
        return page;
    }
