Gibt zurück

TcpStatistics

Ein TcpStatistics-Objekt, das TCP/IPv6-Datenverkehrsstatistiken für den lokalen Computer bereitstellt.

Attribute
UnsupportedOSPlatformAttribute

Ausnahmen

NetworkInformationException

Der Aufruf der Win32-Funktion GetTcpStatistics ist fehlgeschlagen.

PlatformNotSupportedException

Auf dem lokalen Computer wird kein Betriebssystem ausgeführt, das IPv6 unterstützt.

Beispiele

Im folgenden Beispiel werden die TCP/IP-Statistiken für den lokalen Computer angezeigt.

Hinweise

TCP ist ein Transportschichtprotokoll, das für das zuverlässige Senden und Empfangen von Datenpaketen verantwortlich ist. Sie ist in IETF RFC 793 definiert.

Ausführliche Informationen zu den TCP-Datenverkehrsstatistiken, die für Anwendungen verfügbar sind, finden Sie in der TcpStatistics Dokumentation zur Klasse. Beachten Sie, dass das von dieser Methode zurückgegebene Objekt die Statistiken zum Zeitpunkt der Erstellung des TcpStatistics Objekts widerspiegelt. Diese Informationen werden nicht dynamisch aktualisiert.
