Esempio

Commenti

I tipi di interfaccia sono descritti in dettaglio nella documentazione dell'enumerazione System.Net.NetworkInformation.NetworkInterfaceType .

In linea di principio, questa proprietà può restituire qualsiasi membro dell'enumerazione NetworkInterfaceType . Il valore specifico restituito dipende dalle condizioni di runtime della topologia di rete sottostante. Ciò significa che:

• Non è possibile determinare in anticipo quale valore restituisce la proprietà per una determinata rete.

• È possibile che in pratica in una determinata rete l'intera gamma di valori di enumerazione non sia disponibile. Ad esempio, in una rete Gigabit Ethernet, è possibile che la proprietà restituisca NetworkInterfaceType.Ethernet anziché NetworkInterfaceType.GigabitEthernet.
