These days there’s a wealth of information about the new async and await support in the Microsoft .NET Framework 4.5. This article is intended as a “second step” in learning asynchronous programming; I assume that you’ve read at least one introductor…

From time to time, I receive questions from developers which highlight either a need for more information about the new “async” and “await” keywords in C# and Visual Basic. I’ve been cataloguing these questions, and I thought I’d take this opportunit…

Learn how to write a promise based delay function and then use it in async await to see how much it simplifies code over setTimeout. Lets say you want to call a function after 1s, 2s, 3s. You can use setTimeout, or you can wrap it up into a simple de…
Async, Await 是基于 .NEt 4.5架构的, 用于处理异步,防止死锁的方法的开始和结束, 提高程序的响应能力.比如: Application area Supporting APIs that contain async methods Web access HttpClient , SyndicationClient Working with files StorageFile, StreamWrite…
NET 4.5的async/await真是个神奇的东西,巧妙异常以致我不禁对其实现充满好奇,但一直难以窥探其门径.不意间读了此篇强文<Asynchronous Programming in C# using Iterators>,犹如醍醐灌顶,茅厕顿开,思路犹如尿崩.美玉不敢独享,故写此篇,将所学中一些思考与诸君共享,期抛砖引玉,擦出一些基情火花…… 强文<Asynchronous Programming in C# using Iterators>出自大牛,大牛眼界高远.故文中所…
Asynchronous Programming Patterns The .NET Framework provides three patterns for performing asynchronous operations: 1.Asynchronous Programming Model (APM) pattern (also called the IAsyncResult pattern), where asynchronous operations require Begin an…

https://www.markopapic.com/csharp-under-the-hood-async-await/ Async and await keywords came with C# 5 as a cool new feature for handling asynchronous tasks. They allow us to specify tasks to be executed asynchronously in an easy and straightforward f…
最近在看一个线程框架,对.Net的异步编程模型很感兴趣,所以在这里实现CLR定义的异步编程模型,在CLR里有三种异步模式如下,如果不了解的可以详细看MSDN 文档Asynchronous programming patterns. 1.Asynchronous Programming Model (APM)异步编程模式(也叫 IAsyncResult 模式), public class MyClass { public IAsyncResult BeginRead(byte [] buffer,…
