Socket s = new Socket (lep.Address.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

//Using the AddressFamily, SocketType, and ProtocolType properties.
Console.WriteLine ("I just set the following properties of socket: " + "Address Family = " + s.AddressFamily.ToString () + "\nSocketType = " + s.SocketType.ToString () + "\nProtocolType = " + s.ProtocolType.ToString ());
		Socket *s = new Socket(lep->Address->AddressFamily,
			SocketType::Stream, ProtocolType::Tcp);

		//Uses the AddressFamily, SocketType, and ProtocolType properties.
		Console::Write("I just set the following properties of socket: \n");
		Console::Write("Address Family = ");
		Console::Write(__box(s->AddressFamily)->ToString());
		Console::Write("\nSocketType = ");
		Console::Write(__box(s->SocketType)->ToString());
		Console::Write("\nProtocolType = ");
		Console::WriteLine(__box(s->ProtocolType)->ToString());
