在ASP.NET MVC异步控制器 [英] Async controller in ASP.NET MVC

问题描述

我查了System.Web.Mvc.AsyncController在MVC 4.0，它具有提供向后兼容ASP.NET MVC 3的评论这是否意味着没有在MVC 4的新实现异步控制器？什么是MVC中的正确方法使4.0异步为了控制器把I / O操作的激烈比IIS的请求的线程池？

I checked the System.Web.Mvc.AsyncController in MVC 4.0, it has the comment "Provided for backward compatibility with ASP.NET MVC 3." does this mean there is a new implementation of async controller in MVC 4? what's the correct way in MVC 4.0 enable async a controller in order to put the I/O intense operations in other thread pool other than IIS request thread pool?

推荐答案

从ASP.NET MVC 4开始，你现在可以使用 System.Web.Mvc.Controller 类的基类，并利用TAP（基于任务的异步模式）：

Starting from ASP.NET MVC 4, you can now use the System.Web.Mvc.Controller class as the base class and leverage the TAP (Task-based Asynchronous Pattern):

public async Task<ViewResult> Index() { 

     return View(await GetThingsAsync());
}

请注意，您不必使用异步和伺机而附带关键字C＃5.0，但他们做异步编程得多，更容易和更容易维护。

Note that you don't have to use async and await keywords which come with C# 5.0 but they make asynchronous programming much, much easier and more maintainable.
