The C# programming language offers a powerful feature known as the yield keyword, which is primarily used in iterator methods. This keyword provides a convenient and efficient way to implement custom iterators, allowing developers to generate a sequence of values on-the-fly. In this blog post, we'll explore the yield keyword in detail, examining its syntax, use cases, and practical examples. Understanding Iterators: Before delving into the yield keyword, it's essential to have a basic understanding of iterators. An iterator is a construct that allows you to traverse a sequence of values, one at a time, without loading the entire sequence into memory. In C#, iterators are typically implemented using the IEnumerable<T> and IEnumerator<T> interfaces. The yield Keyword Syntax: The yield keyword is used within iterator methods to produce a sequence of values. Its syntax is simple and consists of two main keywords: yield return and yield break. yield return: This keyword ...
