C# yield return Explained

In C#, the yield return keyword is used to define an iterator that returns a series of elements within the iterator. When yield return is used in a method, the method is compiled into an iterator method, allowing the elements in the sequence to be returned one at a time without needing to return all elements at once.

Using yield return can simplify the implementation of many iterators, making the code cleaner and easier to read. When the iterator method is called, elements will be returned one by one in order, and the current state of the iterator can be recorded each time, allowing for lazy computation and memory saving.

In conclusion, the meaning of ‘yield return’ in C# is to define an iterator method and use it to return elements from a sequence one at a time.
