WebClient.OpenWriteCompleted WebClient.OpenWriteCompleted WebClient.OpenWriteCompleted WebClient.OpenWriteCompleted Event

Definition

Tritt ein, wenn ein asynchroner Vorgang zum Öffnen eines Streams, der Daten in eine Ressource schreibt, abgeschlossen wird.Occurs when an asynchronous operation to open a stream to write data to a resource completes.

public:
 event System::Net::OpenWriteCompletedEventHandler ^ OpenWriteCompleted;
public event System.Net.OpenWriteCompletedEventHandler OpenWriteCompleted;
member this.OpenWriteCompleted : System.Net.OpenWriteCompletedEventHandler 
Public Event OpenWriteCompleted As OpenWriteCompletedEventHandler 

Beispiele

Im folgenden Codebeispiel wird das Festlegen eines Ereignis Handlers für dieses Ereignis veranschaulicht.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, wenn ein asynchroner Vorgang zum Öffnen eines Datenstroms, der zum Senden von Daten an eine Ressource verwendet wird, abgeschlossen 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 durch Aufrufen der OpenWriteAsync-Methoden gestartet.These operations are started by calling the OpenWriteAsync methods.

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