使用OpenNI、NiTE、C#、Xtion Pro Live设备进行手势识别

在我的应用程序中，使用来自ASUS Xtion Pro Live设备的输入，我想利用NiTE进行手势识别，因为我自己的手势识别代码基于OpenNI的骨架功能，很笨重，并不完全可靠。

我使用的是OpenNI.net.dll v1.5.2.23和XnVNITE.net.dll v1.5.5.221，这是设备附带的CD。看来他们并没有为v2制作.NET包装器。

为了起步，我写了一些基于NiHandViewer/HandViewer.java示例的代码，但它什么都没做，没有触发任何事件，我也找不到任何有用的NiTE C#示例来指引我正确的方向。

下面的代码出了什么问题？
