Poznámky

Typy rozhraní jsou podrobně popsány v dokumentaci k výčtu System.Net.NetworkInformation.NetworkInterfaceType .

V zásadě může tato vlastnost vrátit libovolný člen výčtu NetworkInterfaceType . Konkrétní hodnota, kterou vrátí, závisí na podmínkách běhu základní síťové topologie. To znamená, že:

  • Není možné předem určit, kterou hodnotu vrátí vlastnost pro konkrétní síť.

  • Je možné, že v praxi v konkrétní síti není k dispozici úplný rozsah hodnot výčtu. Například v gigabitové ethernetové síti je možné, že vlastnost vrátí NetworkInterfaceType.Ethernet místo NetworkInterfaceType.GigabitEthernet.
