c# - C#使用SoundPlayer同时播放多种声音

Question

我想在程序中同时播放多个声音。看到很多在我之前的人问了这个问题，我仔细研究了他们，并决定尝试在不同线程上播放声音。但是，我仍然遇到同样的问题，即正在播放的声音被切成新的声音。

我是否做错了，还是我误会了多线程的可能性？
实现该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。您可以使用它们的异步方法，但不能同时播放多个流，也不能同时播放声音。看到这里:1

您需要使用其他AudioLibrary，例如DirectX或OpenAL。
