What is the proper procedure for shutting down a TCPListener?

Question

Should the Server (the socket) be shutdown before stopping the TcpListener?
sample:
if (theTcpListener != null)
  if (theTcpListener.Server != null)
    if (theTcpListener.Server.Connected)
      theTcpListener.Server.Shutdown(System.Net.Sockets.SocketShutdown.Both);
      theTcpListener.Server.Disconnect(false);
      theTcpListener.Server.Close();
    theTcpListener.Server.Dispose();
  theTcpListener.Stop();
  theTcpListener = null;

>>Should the Server (the socket) be shutdown before stopping the TcpListener?
Close any TcpClient ( TcpClient client = server.AcceptTcpClient(); ) and the call the Stop() method on the TcpListener object. Please refer to the following sample code for more information:

As the documentation states: the Stop method closes the underlying Socket and creates a new Socket for the TcpListener but you are responsible for closing your accepted connections separately:
