A newbie question.
Arrays in C# return a non generic (classic) IEnumerator. Other collections can supply either.
In general, is it bettter use a generic enumerator if it is available, eg for reasons of type safety? Are there times when the non-generic option is preferable?
Usually it’s highly preferable to use generic enumerations, for, as you mentioned in question, type safety.
Non generic enumeration can be a choice in case when you store just a collection of objects.
So instead of writing
IEnumerable<object>, you writeIEnumerableand figure out the real object type inside the iteration (if you need that, but usually yes).
