对象的孩子(children of object)

 我有一个应该返回UIElementCollection的函数。 该函数接受具有children属性的UIElement （即stackpanel ， grid等），但不知道它是哪个UIElement ，所以我将它存储到一般对象中。 
 
public UIElementCollection retCol (object givenObject){
...
}
 
 我想返回givenObject的子givenObject ，但除了将givenObject作为stackpanel或grid格式化之外，我找不到这样做的方法。 
 
 有没有办法可以获得givenObject的children属性？ 

I have a function that is supposed to return a UIElementCollection. The function takes in a UIElement that has the children property (i.e. stackpanel, grid, etc.) but does not know which UIElement it is, so I store it into a general object.
 
public UIElementCollection retCol (object givenObject){
...
}
 
I want to return the children of the givenObject, but I can't find a way to do so besides casting givenObject as a stackpanel or grid.
 
Is there a way I can get the children property of the givenObject?
