WebApr 18, 2013 · C++ standard library iterators are defined in a way to resemble pointers that walk through a collection. In C# every collection that implements IEnumerable can be iterated in a foreach loop. Apart from that you can still do something similar to C++ iterators in C# using Enumerator s (which makes things harder in most cases):
