一般是变量名没定义，或者变量名打错了，你可以再检查一下。

Setting Name from code has limited applications, but getting an element by Name is more common. One particular scenario is if your application supports a navigation model where pages reload into the application, and the run time code is not necessarily code-behind defined for that page. The uti...
