Hinweise

Stopschließt den Listener.Stop closes the listener. Alle nicht akzeptierten Verbindungsanforderungen in der Warteschlange gehen verloren.Any unaccepted connection requests in the queue will be lost. Remote Hosts, die darauf warten, dass eine Verbindung akzeptiert wird, lösen eine aus SocketException .Remote hosts waiting for a connection to be accepted will throw a SocketException. Sie sind dafür verantwortlich, die akzeptierten Verbindungen separat zu schließen.You are responsible for closing your accepted connections separately.

Hinweis

Dieser Member gibt Ablaufverfolgungsinformationen aus, wenn Sie die Netzwerkablaufverfolgung in der Anwendung aktivieren.This member outputs trace information when you enable network tracing in your application. Weitere Informationen finden Sie unter Netzwerk Ablauf Verfolgung in der .NET Framework.For more information, see Network Tracing in the .NET Framework.

Hinweise für Aufrufer

Die Stop() -Methode schließt auch den zugrunde liegenden Socket und erstellt einen neuen Socket für das TcpListener .The Stop() method also closes the underlying Socket, and creates a new Socket for the TcpListener. Wenn Sie vor dem Aufrufen der-Methode Eigenschaften für den zugrunde liegenden festlegen Socket Stop() , werden diese Eigenschaften nicht auf den neuen übertragen Socket .If you set any properties on the underlying Socket prior to calling the Stop() method, those properties will not carry over to the new Socket.
