我试图在按下按钮时让声音循环播放，然后在再次按下相同的按钮时停止声音。我有多个同时播放的声音（所有声音都在循环播放），所有声音都应该能够以任何顺序开始和停止。
我的问题？
如果您按下一个按钮，则声音循环正常，并且当再次按下按钮时它将停止，但是如果您按下一个按钮（所以一个声音正在循环）然后再按另一个（尝试同时播放两种声音）然后第一个声音停止了，我一生都无法弄清楚为什么？
我的代码：
private void button3_Click(object sender, RoutedEventArgs e)
{
SoundEffect sound3;
int x = 0;
StreamResourceInfo SoundFileInfo = App.GetResourceStream(new Uri("tracks/drum (human).wav", UriKind.Relative));
sound3 = SoundEffect.FromStream(SoundFileInfo.Stream);
SoundEffectInstance sound3instance = sound3.CreateInstance();
if (button3.Content.Equals("Sound 3"))
{
sound3instance.IsLooped = true;
sound3instance.Play();
button3.Content = "Playing";
}
else
{
sound3instance.Pause();
button3.Content = "Sound 3";
}
}
private void button4_Click(object sender, RoutedEventArgs e)
{
SoundEffect sound4;
StreamResourceInfo SoundFileInfo2 = App.GetResourceStream(new Uri("Cow Moo 1.wav", UriKind.Relative));
sound4 = SoundEffect.FromStream(SoundFileInfo2.Stream);
SoundEffectInstance sound4instance = sound4.CreateInstance();
if (button4.Content.Equals("Sound 4"))
{
sound4instance.IsLooped = true;
sound4instance.Play();
button4.Content = "PLaying";
}
else
{
sound4instance.Pause();
button4.Content = "Sound 4";
}
}
非常感谢，
