Question

我想在我的程序中同时播放多个声音。看到我之前的很多人都问过这个问题，我仔细查看了它们，并决定尝试在不同的线程上播放声音。但是我仍然遇到同样的问题，即当前正在播放的新声音。

我是否做过错误，或者我是否错过了解多线程这是可能的？实现这个目标的正确方法是什么？

 public class SoundManager
{
    private const int NUM_EFFECT_CHANNELS = 8;
    private const int NUM_AMBIENT_CHANNELS = 2;
    private static Thread[] ambientSounds = new Thread[NUM_AMBIENT_CHANNELS];
    private static Thread[] soundEffects = new Thread[NUM_EFFECT_CHANNELS];
    private static bool[] isPlaying = new bool[NUM_EFFECT_CHANNELS];
    private static bool[] isAmbientPlaying = new bool[NUM_AMBIENT_CHANNELS];

SoundPlayer使用Windows MCI并且不是线程安全的。您可以使用其异步方法，但不能同时播放多个流，也不能同时播放声音。见这里：1

您需要使用另一个AudioLibrary，如DirectX或OpenAL。

C＃与SoundPlayer同时发出多个声音
