如何在C#中同时播放多个声音

我希望能够同时播放多种声音。我尝试使用多线程，但发现它们仍然会一个接一个地播放。有没有办法让他们同时玩？

static void Main(string[] args)
        {
            Console.WriteLine("Hello World");
            Thread th = new Thread(playSound);
            Thread th1 = new Thread(playSound1);

            th.Start();
            th1.Start();


        }

        public static void playSound()
        {
            System.Media.SoundPlayer s1 = new System.Media.SoundPlayer(@"c:\Users\Ben\Documents\c#\note_c.wav");
            s1.Load();
            s1.PlaySync();
        }

        public static void playSound1()
        {
            System.Media.SoundPlayer s1 = new System.Media.SoundPlayer(@"c:\Users\Ben\Documents\c#\note_e.wav");
            s1.Load();
            s1.PlaySync();
        }
    }

如果我们安排并行执行怎么样？ 像那样：

var files = new List<string>() {"note_1.wav", "note_2.wav"};     
Parallel.ForEach(files, (currentFile) => 
{
    System.Media.SoundPlayer s1 = new System.Media.SoundPlayer(currentFile);
    s1.Load();
    s1.PlaySync();
});
