How does a IEnumerator work in C# and not in Unity. For ex: If i have a function that has yield return 8; yield return 10; yield return 15; in 3 lines how does it work. I have answered it based on unity, that i never used numbers returning in a IEnumerator. But later i found out that these IEnumerators can be used in foreach loops like below. And it returns next value on every iteration. foreach(var number in GetNumbers()) { } IEnumerator GetNumbers() { yield return 1; yield return 2; yield return 3; }

Question

Accepted Answer

An IEnumerator in C# is used to iterate over a collection of objects one at a time, allowing for more efficient memory usage and performance.

IEnumerator is used to implement custom iterators in C# by defining a method with a yield return statement.
Each time the iterator is called, it returns the next value in the sequence defined by the yield return statements.
IEnumerators can be used in foreach loops to iterate over the values returned by the iterator.
