Just add the ChildAddress object to the ParentAddress object. As you would for any variable of the class.

For a "simple" list, you merge both sets and "indent" the children; by padding a string (name) on the left with spaces, for example. You can construct entire trees this way without actually building a tree. The "indent level" (size) is one way to know what level you're on.

There are 2 solutions: 1) as Richard pointed out, just add the children class (or a list of it) as property to your parent class and 2) add the parent class as property to your children class. Instead of adding the classes, you could also add the corresponding IDs and use class methods to GetParent() or GetChildren().
