c# - 如何使用MediaPlayer C#停止声音

Question

我具有此功能，并且必须使用MediaPlayer，因为我必须一起播放更多声音。这段代码有效，但是声音不会在键盘上停止(我尝试了一些代码，但是没有起作用)。我该如何停止功能？
谢谢!

private void Form1_KeyDown(object sender, KeyPressEventArgs e)
{
    [...]   // Other code
    playSound(key, name);
}

private void Form1_KeyUp(object sender, KeyEventArgs e)
{
    [...]   // Other code
    stopSound(key, name);
}

private void playSound(string name)
{
    [...]   // Other code
    string url = Application.StartupPath + "\\notes\\" + name + ".wav";
    var sound = new System.Windows.Media.MediaPlayer();

    sound.Open(new Uri(url));
    sound.play();
}

private void stopSound(string name)
{
    ???
}

如果您存储所有在MediaPlayer中创建的List<MediaPlayer>实例的引用，则可以稍后使用此列表访问它们并停止它们。像这样:

List<System.Windows.Media.MediaPlayer> sounds = new List<System.Windows.Media.MediaPlayer>();
private void playSound(string name)
{
    string url = Application.StartupPath + "\\notes\\" + name + ".wav";
    var sound = new System.Windows.Media.MediaPlayer();
    sound.Open(new Uri(url));
    sound.play();
    sounds.Add(sound);
}

private void stopSound()
{
    for (int i = sounds.Count - 1; i >= 0; i--)
    {
        sounds[i].Stop();
        sounds.RemoveAt(i);
    }
}
