I have a question about following variable declaration. What does that mean?

List<string>.Enumerator enumerator

List is a generic type, where string serves as a type parameter.
How to interpret the .Enumerator after that?

    List<T> has a nested class in it, called Enumerator.

    So the type definition of that is List<T>.Enumerator (and in your case T is a string).

    P.S.

    Actually, List<T>.Enumerator is a struct, not a class, anyway the type definition would be the same.

    In fact for all nested types it’s always OuterType.NestedType
