Public Custom Event OpenWriteCompleted As OpenWriteCompletedEventHandler 

Beispiele

Das folgende Codebeispiel veranschaulicht das Festlegen von eines ereignishandlers für dieses Ereignis.The following code example demonstrates setting an event handler for this event.

void OpenResourceForWriting2( String^ address )
{
   WebClient^ client = gcnew WebClient;
   Uri ^uri = gcnew Uri(address);
   
   // Specify that the OpenWriteCallback method gets called
   // when the writeable stream is available.
   client->OpenWriteCompleted += gcnew OpenWriteCompletedEventHandler( OpenWriteCallback2 );
   client->OpenWriteAsync( uri, "POST" );
   
   // Applications can perform other tasks
   // while waiting for the upload to complete.
}


public static void OpenResourceForWriting2 (string address)
{
    WebClient client = new WebClient ();
    Uri uri = new Uri(address);

    // Specify that the OpenWriteCallback method gets called
    // when the writeable stream is available.
    client.OpenWriteCompleted += new OpenWriteCompletedEventHandler (OpenWriteCallback2);
    client.OpenWriteAsync (uri, "POST");
    // Applications can perform other tasks
    // while waiting for the upload to complete.
}

Public Shared Sub OpenResourceForWriting2(ByVal address As String)

	Dim client As WebClient = New WebClient()

	'  Specify that the OpenWriteCallback method gets called
	'  when the writeable stream is available.
	AddHandler client.OpenWriteCompleted, AddressOf OpenWriteCallback2
                      Dim uri as Uri = New Uri(address)
	client.OpenWriteAsync(uri, "POST")
	'  Applications can perform other tasks
	'  while waiting for the upload to complete.
End Sub

Hinweise

Dieses Ereignis wird jedes Mal ausgelöst, die Abschluss eines asynchronen Vorgangs zum Öffnen eines Datenstroms, das zum Senden von Daten auf eine Ressource verwendet wird.This event is raised each time an asynchronous operation to open a stream that is used to send data to a resource completes. Diese Vorgänge werden gestartet, durch den Aufruf der OpenWriteAsync Methoden.These operations are started by calling the OpenWriteAsync methods.

Die OpenWriteCompletedEventHandler ist der Delegat für dieses Ereignis.The OpenWriteCompletedEventHandler is the delegate for this event. Die OpenWriteCompletedEventArgs Klasse stellt den Ereignishandler mit Ereignisdaten bereit.The OpenWriteCompletedEventArgs class provides the event handler with event data.
