FilterAttribute顺序不起作用

Question

I have 2 attributes that I use within the controllers of my MVC application. AttributeA extends System.Web.Mvc.AuthorizeAttribute and AttributeB extends System.Web.Mvc.ActionFilterAttribute . I want AttributeB to always be run first.

I have tried all possible combinations of Order based on this article , but AttributeA is always run before AttributeB. Can anyone help?

如果查看带有反射器的System.Web.Mvc.ControllerActionInvoker.InvokeAction方法，您会看到所有实现IAuthorizationFilter的过滤器在从ActionFilterAttribute派生的属性之前都被调用，这是因为在进行该操作之前已进行了授权。
