What is the difference between Collection<T> and List<T> ?

Both of them implement the same set of interfaces.

Oleg,

The Collection<T> class is intended to be used when you need to
customize the actions of altering the list. For example, the protected
InsertItem method would be overriden when you have custom logic that you
need to implement when an item is inserted into the collection.

The List<T> class does not have these overrides.

The only place to use Collection is a class you create that inherits
from it. Use List for everything else. List has a richer interface
than Collection.

You should also think about your usage patterns and some performance
implications. Here is an excellent article.
