Examples

The OnFileActivated event handler on the Application object receives all file activation events.

protected override void OnFileActivated(FileActivatedEventArgs args)
{
       // TODO: Handle file activation

       // The number of files received is args.Files.Size
       // The first file is args.Files[0].Name
}

Private Sub OnFileActivated(ByVal args As Windows.ApplicationModel.Activation.FileActivatedEventArgs)
      ' TODO: Handle file activation

      ' The number of files received is args.Files.Size
      ' The first file is args.Files(0).Name
End Sub

void App::OnFileActivated(Windows::ApplicationModel::Activation::FileActivatedEventArgs const& /* args */)
{
    // TODO: Handle file activation.

    // The number of files received is args.Files().Size().
    // The first file is args.Files().GetAt(0).Name().
}

void App::OnFileActivated(Windows::ApplicationModel::Activation::FileActivatedEventArgs^ args)
{
       // TODO: Handle file activation

       // The number of files received is args->Files->Size
       // The first file is args->Files->GetAt(0)->Name
}

Remarks

This object is accessed when you implement an event handler to respond to Activated events when ActivationKind is File.

UWP app using C++, C#, or Visual Basic typically implement activation points by overriding methods of the Application object. The default template app.xaml code-behind files always include an override for OnLaunched, but defining overrides for other activation points such as OnFileActivated is up to your app code.

All Application overrides involved in an activation scenario should call Window.Activate in their implementations.

Note that when your app is activated for the file contract you must access the data using the StorageFile objects passed to your app through the Files property. You should not attempt to access the path of the file since your app may not have permission to the file’s location.
