.net上播放MP3

最近在做一个监控项目的时候要求在监控的时候可以采用声音告警，如果用的是VS那么直接调用Media player好了，可惜自己用的是#Develop做为开发环境。居然不支持com组件的引用。我倒~
于是参照MS API写了下面这个简单的播放类

 public class MusicPlayer
 {
  
  
  
  [DllImport("winmm.dll")]
  private  static extern long mciSendString(string strCommand,
  string strReturn, int iReturnLength, IntPtr hwndCallback);
  
  
  public MusicPlayer()
  {
  }
  //播放器状态

  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是选择播放文件类型
   string  ret=null;
   mciSendString(sCommand, ret, 0, IntPtr.Zero);           
        }
  //播放音乐
  public void Play(string filename)   
        {
   Open(filename);   
   string sCommand = "play MediaFile";
   string  ret=null;
         mciSendString(sCommand,ret, 0, IntPtr.Zero);
        }
  //停止播放音乐
  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);
  }
  
 }
}

 

播放的话只要一句就搞定
MusicPlayer mp = new MusicPlayer();
void Button1Click(object sender, System.EventArgs e)
  {
       mp.Play("H:/mp3/十七岁的雨季.mp3");   
  }


另外拿这个测试拉下MONO 1.6 beta 还不错开来MONO也开始支持调用OS本地API了。
