Beispiele

Im folgenden Codebeispiel wird das Festlegen eines Ereignishandlers für dieses Ereignis veranschaulicht.

void UploadStringInBackground2( String^ address )
{
   WebClient^ client = gcnew WebClient;
   Uri ^uri = gcnew Uri(address);
   String^ data = "Time = 12:00am temperature = 50";

   client->UploadStringCompleted += gcnew UploadStringCompletedEventHandler( UploadStringCallback2 );
   client->UploadStringAsync( uri, data );
}

public static void UploadStringInBackground2(string address)
{
    WebClient client = new WebClient();
    Uri uri = new Uri(address);
    string data = "Time = 12:00am temperature = 50";
    client.UploadStringCompleted += new UploadStringCompletedEventHandler(UploadStringCallback2);
    client.UploadStringAsync(uri, data);
}

Public Shared Sub UploadStringInBackground2(ByVal address As String)

    Dim client As WebClient = New WebClient()
    Dim data As String = "Time = 12:00am temperature = 50"
    AddHandler client.UploadStringCompleted, AddressOf UploadStringCallback2
                Dim uri as Uri = New Uri(address)
    client.UploadStringAsync(uri, data)
End Sub

Das folgende Codebeispiel zeigt eine Implementierung eines Handlers für dieses Ereignis.

void UploadStringCallback2( Object^ /*sender*/, UploadStringCompletedEventArgs^ e )
{
   String^ reply = dynamic_cast<String^>(e->Result);
   Console::WriteLine( reply );
}

private static void UploadStringCallback2(Object sender, UploadStringCompletedEventArgs e)
{
    string reply = (string)e.Result;
    Console.WriteLine(reply);
}

Private Shared Sub UploadStringCallback2(ByVal sender As Object, ByVal e As UploadStringCompletedEventArgs)
    Dim reply As String = CStr(e.Result)
    Console.WriteLine(reply)
End Sub

Hinweise

Dieses Ereignis wird jedes Mal ausgelöst, wenn ein asynchroner Zeichenfolgenuploadvorgang abgeschlossen ist. Asynchrone Zeichenfolgenuploads werden durch Aufrufen der UploadStringAsync Methoden gestartet.

Der UploadStringCompletedEventHandler ist der Delegat für dieses Ereignis. Die UploadStringCompletedEventArgs -Klasse stellt den Ereignishandler mit Ereignisdaten bereit.
