最近在做一個監(jiān)控項目的時候要求在監(jiān)控的時候可以采用聲音告警，如果用的是VS那么直接調(diào)用Media player好了，可惜自己用的是#Develop做為開發(fā)環(huán)境。居然不支持com組件的引用。我倒~
于是參照MS API寫了下面這個簡單的播放類

  public string Status
  {
  get{
  string sCommand = "status MediaFile mode";
  string  ret="";
  mciSendString(sCommand, ret, 10, IntPtr.Zero);
  return ret.Trim();
  }
  }
 
  private void Open(string sFileName)
  {
  string sCommand="open \"" + sFileName + "\" type mpegvideo alias MediaFile"; 
  //  MediaFile是選擇播放文件類型
  string  ret=null;
  mciSendString(sCommand, ret, 0, IntPtr.Zero);           
        }
  //播放音樂
  public void Play(string filename) 
        {
  Open(filename); 
  string sCommand = "play MediaFile";
  string  ret=null;
        mciSendString(sCommand,ret, 0, IntPtr.Zero);
        }
  //停止播放音樂
  public void Stop()
  { 
  string sCommand = "stop MediaFile";
  string  ret=null;
  mciSendString(sCommand, ret, 0, IntPtr.Zero);
  }
 
  public void Pause()
  { 
  string sCommand = "pause MediaFile";
  string  ret=null;
  mciSendString(sCommand, ret, 0, IntPtr.Zero);
  }
 
}
}
 
播放的話只要一句就搞定
MusicPlayer mp = new MusicPlayer();
void Button1Click(object sender, System.EventArgs e)
  {
      mp.Play("H:/mp3/十七歲的雨季.mp3"); 
  }


另外拿這個測試拉下MONO 1.6 beta 還不錯開來MONO也開始支持調(diào)用OS本地API了。
