尝试在Visual手势构建器代码中使用“Kinect Region”会产生错误system.reflection.targetinvocationexception

Question

我正在尝试将kinect区域与Visual手势构建器代码一起使用。 我已经为VGB和Wpf控件添加了正确的引用。我正在尝试使用VGB代码注入我的应用程序，这样我就可以在我的应用程序中执行这些自定义手势。

请建议我使用VGB和我的应用程序以及手形光标的方式。我也发布内部异常的图片。

public MainWindow()
        {

            InitializeComponent();

            KinectRegion.SetKinectRegion(this, kinectRegion);

            var app = ((App)Application.Current);
            app.KinectRegion = kinectRegion;

            this.kinectRegion.KinectSensor = KinectSensor.GetDefault();

            var dataSource = DataSource.GetGroup("Group-1");
            this.itemsControl.ItemsSource = dataSource;

            // set IsAvailableChanged event notifier
            this.kinectSensor.IsAvailableChanged += this.Sensor_IsAvailableChanged;

            // open the sensor
            this.kinectSensor.Open();

            // set the status text
            this.StatusText = this.kinectSensor.IsAvailable ? Properties.Resources.RunningStatusText
                                                            : Properties.Resources.NoSensorStatusText;

            // open the reader for the body frames
            this.bodyFrameReader = this.kinectSensor.BodyFrameSource.OpenReader();

            // set the BodyFramedArrived event notifier
            this.bodyFrameReader.FrameArrived += this.Reader_BodyFrameArrived;

            // initialize the BodyViewer object for displaying tracked bodies in the UI


            // initialize the gesture detection objects for our gestures
            this.gestureDetectorList = new List<GestureDetector>();

            // initialize the MainWindow
            this.InitializeComponent();

            // set our data context objects for display in UI
            this.DataContext = this;


            // create a gesture detector for each body (6 bodies => 6 detectors) and create content controls to display results in the UI

            int maxBodies = this.kinectSensor.BodyFrameSource.BodyCount;
            for (int i = 0; i < maxBodies; ++i)
            {
                GestureResultView result = new GestureResultView(false, false, 0.0f);
                GestureDetector detector = new GestureDetector(this.kinectSensor, result);
                this.gestureDetectorList.Add(detector);                

                // split gesture results across the first two columns of the content grid
                ContentControl contentControl = new ContentControl();
                contentControl.Content = this.gestureDetectorList[i].GestureResultView;




            }
        }
