Beispiele

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

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

Hinweise

Klassen, die von dieser Klasse erben, können diese Methode überschreiben, um zusätzliche UploadDataCompleted Aufgaben auszuführen, wenn das Ereignis eintritt.Classes that inherit from this class can override this method to perform additional tasks when the UploadDataCompleted 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 OnUploadDataCompleted-Methode können auch abgeleitete Klassen das Ereignis ohne Anfügen eines Delegaten behandeln.The OnUploadDataCompleted 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.
