菲尔说一个控制器上的ActionFilter是用于应用属性到控制器的所有action方法只是简写，它是真实的，如果我把同样的ActionFilter属性控制器和操作方法，它将运行两次。但是，这似乎是理所当然的行为并不因为编译器甚至不会让你直接多次把同样的属性上的方法。

Phil said an ActionFilter on a controller is just shorthand for applying the attribute to all action methods of the controller, and it is true, if I put the same ActionFilter attribute on the controller and on an action method, it will run twice. But this doesn't seem like natural behavior since the compiler won't even let you put the same attribute directly on a method multiple times.

推荐答案

一个过滤器可以通过specifing每个过滤器订单财产采取precedence了另一个过滤器。例如...

A filter can take precedence over another filter by specifing the Order property on each filter. For example...

[MyFilter(Order=2)]
public class MyController : Controller
{
    [MyFilter(Order=1)]
    public ActionResult MyAction()
    {
    	//...
    }
}

在这个例子中的操作方法过滤器将控制器上的文件管理器之前执行。

In this example the filter on the action method would execute before the filer on the controller.
