Si la SocketPermission instancia se crea con el Unrestricted valor de PermissionState , la SocketPermission instancia pasa todas las demandas. Cualquier otro valor de state da como resultado una instancia de que produce un SocketPermission error en todas las demandas a menos que se agregue un permiso de dirección de transporte con AddPermission.

Este constructor crea un SocketPermission objeto que controla el acceso al especificado hostName y portNumber utilizando el especificado transport.

hostName puede ser un nombre DNS, una dirección IP o una subred IP especificada, como 192.168.1.*.

portNumber puede ser cualquier número de puerto válido definido por el transporte o SocketPermission.AllPorts.
