 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

CODE:
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");
