Async/Await - Best Practices in Asynchronous Programming z

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…

[译]Async/Await - Best Practices in Asynchronous Programming

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.…

将 async/await 异步代码转换为安全的不会死锁的同步代码

在 async/await 异步模型(即 TAP Task-based Asynchronous Pattern)出现以前,有大量的同步代码存在于代码库中,以至于这些代码全部迁移到 async/await 可能有些困难.这里就免不了将一部分异步代码修改为同步代码.然而传统的迁移方式存在或多或少的问题.本文将总结这些传统方法的坑,并推出一款异步转同步的新方法,解决传统方法的这些坑. 背景问题和传统方法为什么有些方法不容易迁移到 async/await? 参见微软的博客 async/await…

Async/Await FAQ

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…
