骨骼数据不像前两个数据，转成字节数组，加载到图片控件上。
一个Kinect for windows设备最多识别6个人，其中只有两个人能识别完整，一个完整的人Kinect for windows中提供了全身20个关节的点，分别为：1、头（Head），2、肩中央（ShoulderCenter），3、左肩（ShoulderLeft），4、右肩（ShoulderRight），5、左肘（ElbowLeft），6、右肘（ElbowRight），7、左腕（WristLeft），8、右腕（WristRight），9、左手（HandLeft），10、右手（HandRight），11、脊柱（Spine），12、 髋中央（HipCenter），13、左髋（HipLeft），14、右髋（HipRight），15、左膝（KneeLeft），16、右膝（KneeRight），17、左髁（AnkleLeft），18、右髁（AnkleRight），19、左脚（FootLeft），20、右脚（FootRight）。
本例可以从骨骼数据中获取这6个人的点，再找到被完整跟踪的人（最多两个人）的20个关节点显示在屏幕上。
新建一个 Winform项目。
然后写如下代码：
1. KinectSensor kinectsensor = null;
2. private void Form1_Shown(object
3. {
4. //从Kinect集合中找到连接上的Kinect
5. foreach (KinectSensor ks in
6. {
7. //找到连接的Kinect
8. if
9. {
10. kinectsensor = ks;
11. //平滑参数
12. new
13. //调用骨骼流
14. kinectsensor.SkeletonStream.Enable(smoothingParam);
15. //设置更近模
16. kinectsensor.DepthStream.Range = DepthRange.Near;
17. //骨骼模式为更近模式
18. true;
19. //坐姿或站姿 坐姿中识别上半身的10个点，默认模式识别全身20个点
20. //kinectsensor.SkeletonStream.TrackingMode = SkeletonTrackingMode.Seated;
21. //订阅骨骼识别事件
22. kinectsensor.SkeletonFrameReady += kinectsensor_SkeletonFrameReady;
23. //开始工作，即可以采集摄像头和红外摄像头信息
24. this.Text = "Kinect开始工作……";
25. return;
26. }
27. }
28. }
29. //定义骨骼数组,因为一个Kinect最多可识别6个人，其中两个人的骨骼的20个点可以识别，另4个人只识别成4个点
30. Skeleton[] skeletonDataArr;
31. void kinectsensor_SkeletonFrameReady(object
32. {
