This is a complex area; I've done some things like this at runtime, and it quickly gets messy. If possible, you might find that the simplest way to do this is to serialize the objects and compare the serialized form (perhaps xml-diff and XmlSerializer). This is complicated a little by the types not being known until runtime, but not hugely (you can always use new XmlSerializer(obj.GetType()) etc).

That would be my default approach, anyway.
