WinForm中播放声音的三种方法

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;
2[DllImport("winmm.dll")]
3        public static extern bool PlaySound(string pszSound, int hmod, int fdwSound);
4        public const int SND_FILENAME = 0x00020000;
5        public const int SND_ASYNC = 0x0001; 
6//调用下面的方法
7PlaySound("folder.wav", 0, SND_ASYNC | SND_FILENAME);
8

2.通过SoundPlayer对象

using System.Media;
2
3SoundPlayer p = new SoundPlayer();
4            p.SoundLocation = Application.StartupPath + "\\folder.wav";        
5            p.Load();
6            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();
2player.SoundLocation = Application.StartupPath + "\\folder.wav";        
3player.Load();
4player.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
2
3Audio a = new Audio();
4          a.Play("folder.wav");
