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…

原文 避免async void async void异步方法只有一个目的:使得event handler异步可行,也就是说async void只能用于event handler. async void方法有不同的错误处理机制.当async Task或者async Task<T>方法里面抛出异常时,异常会被捕捉到,并放在Task对象里面.在async void方法里面没有Task对象,因此发生在async void方法里面的异常会直接raised到SynchronizationContext中.…

本文内容 异步编程类型 异步编程模型(APM) 参考资料 首先澄清,异步编程模式(Asynchronous Programming Patterns)与异步编程模型(Asynchronous Programming Model,APM),它们的中文翻译只差一个字,英文名称差在最后一个单词,一个是 Pattern,一个是 Model.模型 Model 比 模式 Pattern 更具体.前者是一个统称,比后者含义要广,前者包含三个模型,而 APM 只是它其中一个而已. 个人理解,异步编程模型(APM…

Posted by Shiv Kumar on 23rd February, 2011 The Asynchronous Programming Model (or APM) has been around since .NET 1.1 and is still (as of .NET 4.0) the best/recommended solution for asynchronous I/O. Many people go down the route of using a multi-th…

Asynchronous programming can be tricky for beginners, therefore I think it’s useful to iron some basic concepts to avoid common pitfalls. For an explanation about generic asynchronous programming, I recommend you one of the many resourcesonline. I wi…

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…
