Commenti
Se l'istanza viene creata con il Unrestricted valore da PermissionState allora l'istanza SocketPermissionSocketPermission passa tutte le richieste. Qualsiasi altro valore per state i risultati in un'istanza SocketPermission che ha esito negativo su tutte le richieste, a meno che non venga aggiunta un'autorizzazione di indirizzo di trasporto con AddPermission.

Questo costruttore crea un oggetto SocketPermission che controlla l'accesso all'oggetto specificato e portNumber usando l'oggetto specificato hostNametransport.
Può hostName essere un nome DNS, un indirizzo IP o una subnet IP specificata, ad esempio 192.168.1.*.
Può portNumber essere qualsiasi numero di porta valido definito dal trasporto o SocketPermission.AllPorts.
