c# - IEnumeration 之间的区别而是列出?

Question

我很困惑。IEnumeration<T>任何人都可以帮助我理解相反和之间的区别List<T>吗？

Answer 1

You mean IEnumerable<T>. It's the base interface of all collection types like arrays or generic List<T>.

You can for example create a List<int>:

List<int> ints = new List<int>(){ 1,2,3 };

But since it implements IEnumerable<T> you could also declare it in this way:

IEnumerable<int> ints = new List<int>(){ 1,2,3 };

This has the advantage that you cannot modify ints since Remove comes from ICollection<T>.
