Beispiele

Im folgenden Codebeispiel wird das asynchrone Hochladen einer Datei veranschaulicht.The following code example demonstrates asynchronously uploading a file.

// Sample call: UploadFileInBackground2("http://www.contoso.com/fileUpload.aspx", "data.txt")
void UploadFileInBackground2( String^ address, String^ fileName )
{
   WebClient^ client = gcnew WebClient;
   Uri ^uri = gcnew Uri(address);

   client->UploadFileCompleted += 
     gcnew UploadFileCompletedEventHandler (UploadFileCallback2);
   
   // Specify a progress notification handler.
   client->UploadProgressChanged += 
       gcnew UploadProgressChangedEventHandler( UploadProgressCallback );
   client->UploadFileAsync( uri, "POST", fileName );
   Console::WriteLine( "File upload started." );
}


  // Sample call: UploadFileInBackground2("http://www.contoso.com/fileUpload.aspx", "data.txt")
  public static void UploadFileInBackground2 (string address, string fileName)
  {
      WebClient client = new WebClient ();
      Uri uri = new Uri(address);

      client.UploadFileCompleted += new UploadFileCompletedEventHandler (UploadFileCallback2);

// Specify a progress notification handler.
client.UploadProgressChanged += new UploadProgressChangedEventHandler(UploadProgressCallback);
      client.UploadFileAsync (uri, "POST", fileName);
      Console.WriteLine ("File upload started.");
  }

'  Sample call: UploadFileInBackground2("http:' www.contoso.com/fileUpload.aspx", "data.txt")
Public Shared Sub UploadFileInBackground2(ByVal address As String, ByVal fileName As String)

	Dim client As WebClient = New WebClient()
                      Dim uri as Uri =  New Uri(address)
	AddHandler client.UploadFileCompleted, AddressOf UploadFileCallback2

	'  Specify a progress notification handler.
	AddHandler client.UploadProgressChanged, AddressOf UploadProgressCallback
	client.UploadFileAsync(uri, "POST", fileName)
	Console.WriteLine("File upload started.")
End Sub

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

void UploadFileCallback2( Object^ /*sender*/, UploadFileCompletedEventArgs^ e )
{
   String^ reply = System::Text::Encoding::UTF8->GetString( e->Result );
   Console::WriteLine( reply );
}


private static void UploadFileCallback2 (Object sender, UploadFileCompletedEventArgs e)
{
    string reply = System.Text.Encoding.UTF8.GetString (e.Result);
    Console.WriteLine (reply);
}

Private Shared Sub UploadFileCallback2(ByVal sender As Object, ByVal e As System.Net.UploadFileCompletedEventArgs)

    Dim reply As String = System.Text.Encoding.UTF8.GetString(e.Result)
    Console.WriteLine(reply)
End Sub
