xbox 360 kinect光束角度问题与财产变化

Question

试图获得在C＃wpf中的光束角度，并在If PropertyChange抛出异常。有没有人有这个项目的例子，如果需要我可以提供更多的信息。我试图让话筒更改属性，而是它抛出一个异常

 InitializeComponent(); 
     //Beam Angle Code 
     this.DataContext = this.Rect; 
     this.Loaded += delegate { ListenForBeamChanges(); }; 
    } 

    private KinectAudioSource CreateAudioSource() 
    { 
     var source = KinectSensor.KinectSensors[0].AudioSource; 
     source.NoiseSuppression = true; 
     source.AutomaticGainControlEnabled = true; 
     source.BeamAngleMode = BeamAngleMode.Adaptive; 
     return source; 
    } 

    private KinectAudioSource audioSource; 
    private void ListenForBeamChanges() 
    { 
     KinectSensor.KinectSensors[0].Start(); 
     audioSource = CreateAudioSource(); 
     audioSource.BeamAngleChanged += audioSource_BeamChanged; 
     audioSource.Start(); 
    } 

    public double _beamAngle; 
    public double BeamAngle 
    { 
     get { return _beamAngle; } 
     set 
     { 
      _beamAngle = value; 
      OnPropertyChanged("BeamAngle"); 
     } 
    } 

    void audioSource_BeamChanged(object sender, BeamAngleChangedEventArgs e) 
    { 
     BeamAngle = e.Angle * -1; 
    } 

    public event PropertyChangedEventHandler PropertyChanged; 

    public void OnPropertyChanged(string propName) 
    { 
     if (PropertyChanged != null) 
      PropertyChanged(this, new PropertyChangedEventArgs(propName)); 
    } 

    } 
}
