difference between yield and return

The 1.yield keyword is used to traverse loops, and yield return is used to return Ienumerable Implementations that do not use yield return static IEnumerable FilterWithoutYield() { List result = new List(); for

Analysis of yield return usage in C, Note: The yield keyword is used to traverse the loop. The yield return is used to return IEnumerable The following compares the use of yield

Introduction and simple implementation of IEnumerable in C #IEnumerable this interface is said on MSDN, it is a public enumerator that supports simple iterations on non-generic collections.). In other words, the traversal of all arrays comes from IEnumerable, so we can use this feature to define a common way to traverse a string. The following code is posted first. The code is as follows Copy Code Using System;Using System.Collections.Generic;Using System.Linq;Using Sys

Used in an iterator block to provide a value to an enumerator object or to emit an iterative end signal. It is in the form of one of the following:Copy CodeYield return Yield break;NoteEvaluates an expression and returns it as an enumerator object value, and expression must be implicitly convertible to the yield type of the iterator.The

The yield keyword is used to traverse the loop, the yield return is used to return ienumerable There is a set of int types: static List Print all elements with a value greater than 2. Implementation of yield return is not us

ObjectiveIn the previous article I concluded that the value of the item in the iterate iterator modification iterator did not take effect because yield return was used, and each iteration of the iterator executed the method that returned the iterator. This article is followed by the previous article, which verifies the cause of this situation from the point of view of the code implementation.Let's start wit

What is the difference between the sleep () method of the thread class and the Wait () method of the object that allows the thread to pause execution?The Sleep () method (Hibernate) is a static method of the thread class (threads), which causes the current thread to pause execution for a specified time, giving the execution opportunity (CPU) to another thread, but the lock on the object remains , so that it is automatically restored after the sleep ti

The code is as follows: After using yield return in the Documents1 method, the next time you enter the Documents1 method is to execute from the last yield return part usingSystem;usingSystem.Collections;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Threading;usingSystem.Threading.Tasks;n
