Uwagi
Ten konstruktor tworzy obiekt SocketPermission , który kontroluje dostęp do określonego hostName elementu i portNumber przy użyciu określonego transportelementu .
Może hostName to być nazwa DNS, adres IP lub określona podsieć IP, taka jak 192.168.1.*.
Może portNumber to być dowolny prawidłowy numer portu zdefiniowany przez transport lub SocketPermission.AllPorts.
