Question

我有2个按钮，播放和暂停，当我点击暂停时，音乐停止，当我点击播放时，它从头开始播放音频。我想这样做，就像我按下播放，它从我停止的地方恢复。

        private void PlayAudio()
    {


        McMediaElement.LoadedBehavior = MediaState.Manual;
        McMediaElement.Source = new Uri("../../SingAlong/Food Fit For A King/old king cole.mp3", UriKind.RelativeOrAbsolute);
        McMediaElement.Play();
    }

    private void button1_Click_1(object sender, RoutedEventArgs e)
    {
        PlayAudio();

    }

    private void button2_Click(object sender, RoutedEventArgs e)
    {
        McMediaElement.Pause();
    }

Answer 1

设置PlayAudio()属性时，Source方法会重新加载媒体文件。这会导致您的对象在调用Play()时从头开始播放新加载的媒体。不应在事件处理程序button1_Click_1中执行此操作，而应仅调用Play()方法：

private void button1_Click_1(object sender, RoutedEventArgs e)
{
    McMediaElement.Play();
}

Answer 2

这对我有用..

private void button1_Click_1(object sender, RoutedEventArgs e)
{
   McMediaElement.LoadedBehavior = MediaState.Pause;
}
private void button2_Click_1(object sender, RoutedEventArgs e)
{
   McMediaElement.LoadedBehavior = MediaState.Play;
}

WPF MediaElement如何从暂停的地方恢复播放？
