C#播放背景音樂通常有四種方式:
1.播放系統事件聲音
2.使用System.Media.SoundPlayer播放wav------------------------僅僅是對波形音樂
3.使用MCI Command String多媒體裝置程式介面播放mp3,avi等
4.使用axWindowsMediaPlayer的COM組件來播放
1.播放系統事件聲音
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多媒體裝置程式介面播放mp3,avi等

關於mciSendString的詳細參數說明,請參見MSDN,或是 http://blog.csdn.net/psongchao/archive/2007/01/19/1487788.aspx
4.使用axWindowsMediaPlayer的COM組件來播放
a.載入COM組件:添加引用-->Com組件--> Windows Media Player如:
b.把Windows Media Player控制項拖放到Winform表單中,把axWindowsMediaPlayer1中URL屬性設定為MP3或是AVI的檔案路徑,F5運行。
如何使用Windows Media Player迴圈播放清單中的媒體檔案?
假設我們有一個播放清單,下面的代碼可以實現自動迴圈播放
MediaPlayer.MediaPlayer mr = new MediaPlayer.MediaPlayer();mr.FileName = txpath.Text.Trim();mr.Play();
MCI Command String和Windows Media Player都有非常豐富的功能介面,這裡不能一一介紹,可以參考MSDN中的具體描述.
