如何检测C#播放的媒体？

using System.Windows.Controls;

MediaElement mediaElement = new MediaElement();

mediaElement.Source = new Uri("path_to_media_file");

mediaElement.Play();

mediaElement.MediaOpened += MediaElement_MediaOpened;

private void MediaElement_MediaOpened(object sender, RoutedEventArgs e)
{
    TimeSpan duration = mediaElement.NaturalDuration.TimeSpan;
    // 在此处处理媒体总时长
}

mediaElement.MediaEnded += MediaElement_MediaEnded;

private void MediaElement_MediaEnded(object sender, RoutedEventArgs e)
{
    // 在此处处理媒体播放结束的逻辑
}

// 获取当前播放的时间
TimeSpan currentPosition = mediaElement.Position;

mediaElement.Stop();
