1.        播放系统事件声音
System.Media.SystemSounds.Asterisk.Play();
System.Media.SystemSounds.Beep.Play();
System.Media.SystemSounds.Exclamation.Play();
System.Media.SystemSounds.Hand.Play();
System.Media.SystemSounds.Question.Play();
2.        使用System.Media.SoundPlayer播放.wav音乐文件
System.Media.SoundPlayer sp = new SoundPlayer();
sp.SoundLocation = @"D:\TestMusic.wav";
sp.PlayLooping();
3.        使用非托管的dll播放.wav音乐文件
using System.Runtime.InteropServices;
class PlayMusic
{  
    [DllImport("winmm.dll")]
    public static extern bool PlaySound(String Filename,int Mod,int Flags);
  
    public void Main()
    {  
        PlaySound(@"D:\TestMusic.wav",0,1);   //第3个形参,把1换为9,连续播放
    }
}
4.        使用MCI Command String多媒体设备程序接口播放.mp3,.avi等音乐文件
using System.Runtime.InteropServices;
public static uint SND_ASYNC = 0x0001;
public static uint SND_FILENAME = 0x00020000;
[DllImport("winmm.dll")]
public static extern uint mciSendString(string lpstrCommand,
    string lpstrReturnString, uint uReturnLength, uint hWndCallback);
public void Play()
{   
  mciSendString(@"close temp_alias", null, 0, 0);
  mciSendString(@"open ""D:\TestMusic.mp3"" alias temp_alias", null, 0, 0);
  mciSendString("play temp_alias repeat", null, 0, 0);
}
5.        使用axWindowsMediaPlayer的COM组件播放.mp3或.avi音乐文件
1)        加载COM组件:ToolBox->Choose Items->COM Components->Window Media Player。
2)        把Windows Media Player控件拖到窗体中,把axWindowsMediaPlay1的URL属性设置为.mp3或.avi音乐文件的路径,运行程序即可。
3)        使用Windows Media Player循环播放音乐文件:
private void axWindowsMediaPlayer1_PlayStateChange(object sender,
    AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
{   
  if (axWindowsMediaPlayer1.playState == WMPLib.WMPPlayState.wmppsMediaEnded)
  {   
      Thread thread = new Thread(new ThreadStart(PlayThread));
      thread.Start();
  }   
}   
private void PlayThread()
{   
  axWindowsMediaPlayer1.URL = @"D:\TestMusic.avi";
  axWindowsMediaPlayer1.Ctlcontrols.play();
}
