推荐答案

不太确定您的问题，因为您显示的代码将起作用，但是如果您在像tabcontrol这样的容器中有控件，则需要单独迭代这些控件，因为它们不是你正在迭代的容器。



最简单的方法是使用一个递归函数将容器控件作为参数传递，当它发现一个控件让子控件传递给控件时调用它自己争论。



快示例（未经过我头脑的测试）。

Not quite sure of your question as the code you show will work, however if you have controls inside a container like a tabcontrol you need to iterate those controls separately as they are not members of the container you are iterating.

Easiest way is to use a recursive function passing the container control as argument and calling itself when it find a control has children passing that control as argument.

Quick example (not tested written of the top of my head).

public sub WalkControls(TopControl as Control)
   For Each x As Control In TopControl.Controls
       If x.HasChildren Then
          WalkControls(x)
       Else
'
' Do what you want to do with the control
'
       End If
   Next
End sub
