VB.NET WPF MediaElement循环播放视频和音频

VB.NET和WPF开发中用MediaElement循环播放视频和音频，在MediaEnded事件中加入处理方法，代码如下

Private Sub bgVideo_MediaEnded(sender As Object, e As RoutedEventArgs) Handles bgVideo.MediaEnded
    bgVideo.Position = TimeSpan.FromMilliseconds(0)
    bgVideo.Play()
End Sub

注意点：bgVideo的LoadedBehavior和UnloadedBehavior都必须设置为Manual
