Observações

Stop fecha o ouvinte. Quaisquer pedidos de ligação não aceites na fila serão perdidos. Hosts remotos que aguardam que uma ligação seja aceite irão lançar um SocketException. És responsável por fechar as tuas ligações aceites separadamente.

Notas para Chamadores

O Stop() método também fecha o subjacente Socket, e cria um novo Socket para o TcpListener. Se definir quaisquer propriedades no subjacente Socket antes de chamar o Stop() método, essas propriedades não serão transferidas para o novo Socket.
