添加声音的代码

来源:互联网 发布:阿唯得旗舰店淘宝 编辑:程序博客网 时间:2024/05/17 08:14

 

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

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


  3.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);
  }


   4.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:/Music/SomeOne.avi";
  axWindowsMediaPlayer1.Ctlcontrols.play();
  }


  MCI Command String和Windows Media Player都有非常丰富的功能接口,这里不能一一介绍,可以参考MSDN中的具体描述.
