foreach with generic list class

[aronmatthew]

Does anyone have a List Enumerator example for generic list class. One that inherits from IEnumerator. Such that foreach can be used for generic list class.

There should be no need. If you're defining your own collection class then it should inherit Collection<T> and you get that functionality for free. Is there any reason that you can't do that?

as is I'm simply using a field List<T>. I am not at all familiar with the Collection class. It should work this way also.

If you look at the documentation, you'll see that List<T> implements IEnumerable<T>:

List<T> Class (System.Collections.Generic)

Represents a strongly typed list of objects that can be accessed by index. Provides methods to search, sort, and manipulate lists.

And then if you refer back to the C# foreach keyword documentation, you'll see that the keyword operates on any IEnumerable<T>:

Iteration statements -for, foreach, do, and while - C# reference

C# iteration statements (for, foreach, do, and while) repeatedly execute a block of code. You use those statements to create loops or iterate through a collection.

Then a foreach loop will already work, so what problem are you actually trying to solve? It's not clear that there is one. What exactly is it that you want to do that you are unable to?
