        private string musicPath;

        public MCIPlay(string musicPath)
        {
            this.musicPath = musicPath;
        }

        public void Play()
        {
            mciSendString(@"close temp_alias", null, 0, 0);
            mciSendString(@"open "+musicPath+" alias temp_alias", null, 0, 0);
            mciSendString("play temp_alias ", null, 0, 0);
        }
    }
