Hinweise

Stop schließt den Listener. Alle nicht empfangenen Verbindungsanforderungen in der Warteschlange gehen verloren. Remotehosts, die darauf warten, dass eine Verbindung akzeptiert wird, lösen einen aus SocketException. Sie sind dafür verantwortlich, Ihre akzeptierten Verbindungen separat zu schließen.

Hinweise für Aufrufer

Die Stop() -Methode schließt auch den zugrunde liegenden Socketund erstellt eine neue Socket für die TcpListener. Wenn Sie vor dem Aufrufen der Stop() -Methode Eigenschaften für den zugrunde liegenden Socket festlegen, werden diese Eigenschaften nicht auf die neue Socketübertragen.
