Is there a better data structure than Dictionary if the values are objects and a property of those objects are the keys?

Question

Answer 1

There is a KeyedCollection class.

EDIT: The KeyedCollection can use a dictionary internally, but it cleaner interface for this particular scenario than a raw dictionary since you can lookup by values directly. Admittedly I don't find it very useful in general.
