声音文件folder.wav放置在bin目录下debug下

1.通过API调用

using System.Runtime.InteropServices;  
[DllImport("winmm.dll")]  
        public static extern bool PlaySound(string pszSound, int hmod, int fdwSound);  
        public const int SND_FILENAME = 0x00020000;  
        public const int SND_ASYNC = 0x0001;   
//调用下面的方法  
PlaySound("folder.wav", 0, SND_ASYNC | SND_FILENAME);  

2.通过SoundPlayer对象

using System.Media;  
  
SoundPlayer p = new SoundPlayer();  
            p.SoundLocation = Application.StartupPath + "//folder.wav";          
            p.Load();  
            p.Play();  

SoundPlayer

支持同步、异步播放
支持循环播放
支持文件和流播放

同步播放：

    System.Media.SoundPlayer player = new System.Media.SoundPlayer();  
    player.SoundLocation = Application.StartupPath + "//folder.wav";          
    player.Load();  
    player.Play(); 

异步播放：

System.Media.SoundPlayer player = new System.Media.SoundPlayer();  
player.SoundLocation = Application.StartupPath + "//folder.wav";  
player.LoadAsync();  
player.PlaySync();  

循环播放

System.Media.SoundPlayer player = new System.Media.SoundPlayer();  
player.SoundLocation = Application.StartupPath + "//folder.wav";  
player.Load();  
player.PlayLooping();  

3.使用 Audio 对象

using Microsoft.VisualBasic.Devices;//Microsoft.VisualBasic.dll需要添加引用  
  
Audio a = new Audio();  
          a.Play("folder.wav");
