derive from IEnumerator<T>

Hello everyone,


I am wondering why do we need to derive some type from IEnumerator<T>? Could anyone show me some useful samples?

I think using IEnumerator<T> itself should be enough in all cases?


thanks in advance,
George

Thanks indigo0086,


My question is about how to write the generics form IEnumeraot<T>, especially how to write the constructor and dealing with T. Your referred link is about the non-generics form of IEnumerator.

Any more ideas or references? :-)
