WPF:实现MediaPlayer音频/视频搜索器

ARISE回答!侍奉你的主人

这是WPF应用程序的代码,带有暂停/播放按钮。

public partial class Main : Window
{
    MediaPlayer MPlayer;
    MediaTimeline MTimeline;

    public Main()
    {
        InitializeComponent();

        var uri = new Uri("C:\\Test.mp3");
        MPlayer = new MediaPlayer();
        MTimeline = new MediaTimeline(uri);
        MTimeline.CurrentTimeInvalidated += new EventHandler(MTimeline_CurrentTimeInvalidated);
        MPlayer.Clock = MTimeline.CreateClock(true) as MediaClock;
        MPlayer.Clock.Controller.Stop();
    }

    void MTimeline_CurrentTimeInvalidated(object sender, EventArgs e)
    {
        Console.WriteLine(MPlayer.Clock.CurrentTime.Value.TotalSeconds);
    }

    private void btnPlayPause_Click(object sender, RoutedEventArgs e)
    {
        //Is Active
        if (MPlayer.Clock.CurrentState == ClockState.Active)
        {
            //Is Paused
            if (MPlayer.Clock.CurrentGlobalSpeed == 0.0)
                MPlayer.Clock.Controller.Resume();
            else //Is Playing
                MPlayer.Clock.Controller.Pause();
        }
        else if (MPlayer.Clock.CurrentState == ClockState.Stopped) //Is Stopped
            MPlayer.Clock.Controller.Begin();
    }
}

暂停歌曲等时,你必须停止计时器。。。
