本文是转载的文章。原文出处：http://blog.csdn.net/jijunwu/article/details/4753094

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");
