Re: Garbage Collection

The framework collections do not implement IDisposable.
You can implement you own collection class that implements IDisposable
interface. In the dispose method loop throw all objects and dispose those
which are not null and implements IDisposable.

Please note that disposing the whole collection is not a good idea if the
objects in the collections are referenced by another objects.
