derive from IEnumerator

Question

Hello everyone I am wondering why do we need to derive some type from IEnumerator ? Could anyone show me some useful samples? I think using IEnumerator itself should be enough in all cases? thanks in advance George

Thanks buddy What makes me confused is about how to write the constructor of the class which implements IEnumarator  could you show me a sample please? regards George

IEnumerator is a generic IEnumerator interface which allows you to create a generic enumerator for enumerating through lists :) Ive never used it though... Also its just coding etiquette but you dont technically derive from an interface you implement it. And interface basically says that this certain class (the class that implements it) is guaranteed to have these members. It works nicely in generics much like a base class but it does not declare instance members. Meaning you dont have to worry about the base members it contains.
