[转载]C#中播放背景音乐几种的方法

最经在写winform程序,其中有用到播放背景音乐

特此收集了一些网上的教程:

1、调用非托管的dll

        using System.Runtime.InteropServices;  //DllImport命名空间的引用   
    class test  //提示音
    {
        [DllImport("winmm.dll")]
        public static extern bool PlaySound(String Filename,int Mod,int Flags);

        public void Main()
        {
            PlaySound(@"d:/qm.wav",0,1);   //把1替换成9,可连续播放
        }
        }

2、播放系统自带声音

    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();

3、使用System.Media.SoundPlayer播放wav

System.Media.SoundPlayer sp = new SoundPlayer(); 
  sp.SoundLocation = @"D:10sec.wav"; 
  sp.PlayLooping();

4、使用MCI Command String多媒体设备程序接口播放mp3,avi等

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 ""E:Music青花瓷.mp3"" alias temp_alias", null, 0, 0); 
  mciSendString("play temp_alias repeat", null, 0, 0); 
  }

关于mciSendString的详细参数说明,请参见MSDN,或是 http://blog.csdn.net/psongchao/archive/2007/01/19/1487788.aspx

5、使用axWindowsMediaPlayer的COM组件来播放

a.加载COM组件:ToolBox->Choose Items->COM Components->Windows Media Player如下图:

b.把Windows Media Player控件拖放到Winform窗体中,把axWindowsMediaPlayer1中URL属性设置为MP3或是AVI的文件路径,F5运行。

  如何使用Windows Media Player循环播放列表中的媒体文件?

  假设我们有一个播放列表,下面的代码可以实现自动循环播放

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 = @"E:MusicSomeOne.avi"; 
  axWindowsMediaPlayer1.Ctlcontrols.play(); 
  }
