IPStatus

Hodnota IPStatus označující výsledek požadavku.

Příklady

Následující příklad kódu ukazuje použití Ping třídy k odeslání žádosti o odezvu ICMP synchronně a zobrazení odpovědi.

Poznámky

Pokud hodnota Status není , neměli byste použít hodnoty vrácené hodnotou nebo OptionsBuffer vlastnostmiRoundtripTimeSuccess. Vlastnosti RoundtripTime vrátí nulu Options a vlastnost vrátí null.Buffer
