我为 XNA 找到了这个类，它可以满足我的需求，但在 Metro 下不可用:http://msdn.microsoft.com/en-us/library/microsoft.xna.framework.audio.soundeffectinstance.aspx
I found this class for XNA which does what I want, but is not available under Metro: http://msdn.microsoft.com/en-us/library/microsoft.xna.framework.audio.soundeffectinstance.aspx
推荐答案
只需为每个音效创建一个单独的媒体元素.
Just create a separate media element for every sound effect.
(不确定我是否每次都需要重新定位文件)
(not sure I need to relocate the file every time)
public async void PlayLaserSound()
{
var package = Windows.ApplicationModel.Package.Current;
var installedLocation = package.InstalledLocation;
var storageFile = await installedLocation.GetFileAsync("Assets\Sounds\lazer.mp3");
if (storageFile != null)
{
var stream = await storageFile.OpenAsync(Windows.Storage.FileAccessMode.Read);
MediaElement snd = new MediaElement();
snd.SetSource(stream, storageFile.ContentType);
snd.Play();
}
}
