WPF MediaElement 如何从暂停处恢复播放？

Question

我有 2 个按钮，播放和暂停，当我单击暂停时，音乐停止，当我单击播放时，它从头开始播放音频。我想像当我按“播放”时一样，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

当您设置

PlayAudio()

 属性时，您的 

Source

 方法会重新加载媒体文件。这会导致您的对象在您调用 

Play()

 时从头开始播放新加载的媒体。您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;
}

Answer 3

Many years have passed, but maybe it will be useful to someone..

This works well for me:

bool isPaused = false;

// Button play
private void button1_Click_1(object sender, RoutedEventArgs e)
{
   if(!isPaused){
// Do all what You want
}
isPaused = false;
myMediaElement.Play();
}

// Button Pause:
private void button2_Click_1(object sender, RoutedEventArgs e)
{
  isPaused = true;
  myMediaElement.Pause();
}
