请看我对这个问题的评论。很明显，如果不是一般的编程，你会对WPF开发的基础知识感到困惑。

对于WPF的一般理解，在此a至少在一般概念中你需要理解它的内容模型： https://msdn.microsoft.com/en-us/library/bb613548%28v=vs.110%29.aspx [ ^ ]。

Please see my comment to the question. It's apparent that you are quite confused with the very basics of WPF development, if not programming in general.

Please see:
https://msdn.microsoft.com/en-us/library/System.Windows.Controls.Panel%28v=vs.110%29.aspx#inheritanceContinued[^],
https://msdn.microsoft.com/en-us/library/system.windows.controls.panel.children%28v=vs.110%29.aspx[^].

For general WPF understanding, in this aspect, you need to understand its Content Model at least in general concepts: https://msdn.microsoft.com/en-us/library/bb613548%28v=vs.110%29.aspx[^].
