Exemples

L’exemple de code suivant illustre la définition d’un gestionnaire d’événements pour cet événement.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

Remarques

Cet événement est déclenché chaque fois une opération asynchrone pour ouvrir un flux qui est utilisé pour envoyer des données à une ressource.This event is raised each time an asynchronous operation to open a stream that is used to send data to a resource completes. Ces opérations sont démarrées en appelant le OpenWriteAsync méthodes.These operations are started by calling the OpenWriteAsync methods.

Le OpenWriteCompletedEventHandler est le délégué de cet événement.The OpenWriteCompletedEventHandler is the delegate for this event. Le OpenWriteCompletedEventArgs classe fournit le Gestionnaire d’événements avec les données d’événement.The OpenWriteCompletedEventArgs class provides the event handler with event data.
