How to create a list of parent objects where each

问题:

In VB.NET 2010, How would one go about creating a list of Parent classes where each Parent has it's own list of Child classes. Where the list of child classes could be as few as 1 child or as many as a few hundred child objects?

回答1:

Dim ChildList as generic.list(of object)
Dim ParentList as generic.list(of ChildList)

You can do it like above

回答2:

Sounds like you need a LinkedList object:

LinkedList Outer;

where ParentType is a class that has another LinkedList object of it own:

Public Class ParentType

    Private myChildren As LinkedList<ChildType>

ChildType in above could even be replaced with "ParentType," if it's a list of the exact same kind of object.
