System.Collecti ons.Generic.Lis t (v2.0)

I've noticed that in VS.NET 2.0 Beta 1 that none of the methods in
System.Collecti ons.Generic.Lis t are overridable. In my app I currently have
over 50 strongly typed ArrayLists that inherit from
System.Collecti ons.ArrayList. Each of these types raise strongly typed
events for when items are added and removed (e.g., AddingItem, AddedItem,
CollectionChang ed, etc.). One of my hopes for v2.0 was to create a single
generic List that replaces all of my current ArrayLists. But, if methods in
System.Collecti ons.Generic.Lis t are not overridable then I won't be able to
insert the necessary code for raising the events. Note that shadowing the
necessary methods is not safe because code that is executed outside of my
application will not call the shadowed methods (e.g., when the List is being
edited by a PropertyGrid).

Can somebody tell me if methods in System.Collecti ons.Generic.Lis t are
expected to be overridable in the final version of VS.NET 2.0 as they are in
System.Collecti ons.ArrayList?

But you can still write a generic class that implements IList(Of T)
and uses List(Of T) internally for storage.

I am trying to use reflection to output the fields (names and values) of an arbitrary object -- an object dump to a TreeView. It works pretty well, but I am having trouble with generic lists, like List<char>. What I have working is : Type type = newObj.GetType(); //newObj is what I'm trying to dump

I am trying to use reflection in a property of a base type to inspect the properties of an instance of a type which is derived from that base type, when the properties can themselves be instances of types derived from that base type, or arrays or generic collections of instances of types derived from that base type.
