What is an IEnumerator C#?

What is an IEnumerator C#?

IEnumerable in C# is an interface that defines one method, GetEnumerator which returns an IEnumerator interface. This allows readonly access to a collection then a collection that implements IEnumerable can be used with a for-each statement.

How does an IEnumerator differ from an IEnumerable?

An IEnumerator is a thing that can enumerate: it has the Current property and the MoveNext and Reset methods (which in . NET code you probably won’t call explicitly, though you could). An IEnumerable is a thing that can be enumerated…which simply means that it has a GetEnumerator method that returns an IEnumerator .

What is IEnumerable and IEnumerator in C#?

IEnumerable is an interface defining a single method GetEnumerator() that returns an IEnumerator interface. This works for readonly access to a collection that implements that IEnumerable can be used with a foreach statement. IEnumerator has two methods MoveNext and Reset. It also has a property called Current.

How do you end a coroutine?

To stop a coroutine from “inside” the coroutine, you cannot simply “return” as you would to leave early from an ordinary function. Instead, you use yield break . You can also force all coroutines launched by the script to halt before finishing.
