How does an IEnumerator work in C# and outside of Unity? For example, if a function contains 'yield return 8; yield return 10; yield return 15;' on three separate lines, how does it operate?

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.
