Beispiele

Im folgenden Codebeispiel wird eine Implementierung dieser Methode gezeigt, die von einer Klasse angepasst werden kann, die von WebClient abgeleitet ist.The following code example shows an implementation of this method that can be customized by a class derived from WebClient.

virtual void OnOpenWriteCompleted( OpenWriteCompletedEventArgs ^ e ) override
{
   // Here you can perform any custom actions before the event is raised
   // and event handlers are called...
   WebClient::OnOpenWriteCompleted( e );

   // Here you can perform any post event actions...
}
protected override void OnOpenWriteCompleted (OpenWriteCompletedEventArgs e)
{
    // Here you can perform any custom actions before the event is raised
    // and event handlers are called...

    base.OnOpenWriteCompleted (e);

    // Here you can perform any post event actions...
}

Hinweise

Klassen, die von dieser Klasse erben, können diese Methode überschreiben, um zusätzliche Aufgaben auszuführen, wenn das OpenWriteCompleted-Ereignis auftritt.Classes that inherit from this class can override this method to perform additional tasks when the OpenWriteCompleted event occurs.

Durch das Auslösen eines Ereignisses wird der Ereignishandler über einen Delegaten aufgerufen.Raising an event invokes the event handler through a delegate. Weitere Informationen finden Sie unter Behandeln und Auslösen von Ereignissen.For more information, see Handling and Raising Events.

Mit der OnOpenWriteCompleted-Methode können auch abgeleitete Klassen das Ereignis ohne Anfügen eines Delegaten behandeln.The OnOpenWriteCompleted method also allows derived classes to handle the event without attaching a delegate. Dies ist das bevorzugte Verfahren für die Behandlung des Ereignisses in einer abgeleiteten Klasse.This is the preferred technique for handling the event in a derived class.

Hinweise für Vererber

Wenn Sie OnOpenWriteCompleted(OpenWriteCompletedEventArgs) in einer abgeleiteten Klasse überschreiben, stellen Sie sicher, dass Sie die OnOpenWriteCompleted(OpenWriteCompletedEventArgs)-Methode der Basisklasse aufzurufen, damit registrierte Delegaten das Ereignis empfangen.When overriding OnOpenWriteCompleted(OpenWriteCompletedEventArgs) in a derived class, be sure to call the base class' OnOpenWriteCompleted(OpenWriteCompletedEventArgs) method so that registered delegates receive the event.
