• [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(); 
      }
