Poznámky

Pokud je SocketPermission instance vytvořená s Unrestricted hodnotou z PermissionState , SocketPermission pak instance projde všemi požadavky. Jakákoli jiná hodnota způsobí stateSocketPermission , že instance nesplní všechny požadavky, pokud není přidáno oprávnění k přenosové adrese s AddPermission.

Poznámky

Tento konstruktor vytvoří SocketPermission , který řídí přístup k zadanému hostName a portNumber pomocí zadaného transport.

Může hostName to být název DNS, IP adresa nebo zadaná podsíť PROTOKOLU IP, například 192.168.1.*.

Může portNumber to být libovolné platné číslo portu definované přenosem nebo SocketPermission.AllPorts.
