c csharp what is the use of yield keyword in c

Download 1M+ code from https://codegive.com/86cbab3 the `yield` keyword is not a feature of the c programming language. instead, it is used in c (c sharp). in c, `yield` is used to simplify the implementation of iterators. an iterator is a method, property, or indexer that returns an `ienumerable` or `ienumerator`. the `yield` keyword allows you to return each element of a collection one at a time, without needing to create and manage a separate collection to hold the results. what is `yield` in c? when you use the `yield` keyword in a method, you can return an element of a collection, and the state of the method is preserved. when the method is called again, it resumes execution right after the last `yield` statement. benefits of using `yield` **memory efficient**: you don't need to create a separate collection to store all items before returning them. **simplifies code**: you can easily write iterators without needing to implement the `ienumerable` or `ienumerator` interfaces manually. **on-demand execution**: elements are generated on-the-fly as they are requested. example of using `yield` here’s an example demonstrating how to use the `yield` keyword in c to create a simple iterator: explanation of the example 1. **getnumbers method**: this method takes an integer `count` and uses a `for` loop to yield integers from 0 to `count - 1`. 2. **yield return**: each time the `yield return` statement is reached, the current value of `i` is returned to the caller, and the method's state is saved. 3. **main method**: in the `main` method, we call `getnumbers(5)` and iterate over the returned numbers using a `foreach` loop. the numbers 0, 1, 2, 3, and 4 will be printed to the console. key points to remember the `yield` keyword can be used with both `ienumerablet` and `ienumeratort`. when a method containing `yield` is called, it does not execute the method body immediately. instead, it returns an iterator that can be used to iterate over the results. once a `yield return` statement is execut ... #CSharp #YieldKeyword #coding C#coding yield keyword iterator IEnumerable IEnumerableT deferred execution lazy evaluation state machine coroutine collection iteration performance optimization generator methods async programming C# 2.0
