Beispiele

Im folgenden Codebeispiel wird veranschaulicht, eine Zeichenfolge asynchron hochladen.The following code example demonstrates asynchronously uploading a string.

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

Die folgende Methode wird aufgerufen, wenn der Upload abgeschlossen ist.The following method is called when the upload completes.

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
