问题描述

我看到有两个版本的ActionFilterAttribute类.
System.Web.Mvc.ActionFilterAttribute 和 System.Web.Http.Filters.ActionFilterAttribute

i see that there are two version of ActionFilterAttribute class.
System.Web.Mvc.ActionFilterAttribute and System.Web.Http.Filters.ActionFilterAttribute

有什么不同?

推荐答案

System.Web.Mvc 一个用于以前的MVC版本.

The System.Web.Http one is for Web API; the System.Web.Mvc one is for previous MVC versions.

从源头上可以看到，Web API版本具有一些差异.

You can see from the source that the Web API version has several differences.

• 它具有OnResultExecuting和OnResultExecuted处理程序(由ASP.NET MVC框架在执行操作结果之前/之后调用." )
• 可以异步执行
• 不是允许您指定执行顺序

• It has OnResultExecuting and OnResultExecuted handlers ("Called by the ASP.NET MVC framework before/after the action result executes.")
• It can be executed asynchronously
• It does not let you specify an order of execution
