AuthorizeAttribute
请问下，[Authorize(Roles = "Admin, Super User")]，[Authorize(Users = "Betty, Johnny")]，是在什么地方被设置的？

谢谢

[HandleError]
 public class HomeController : Controller
 {
     public ActionResult Index()
     {
         ViewData["Message"] = "Welcome to ASP.NET MVC!";

         return View();
     }

     public ActionResult About()
     {
         return View();
     }

     [Authorize]
     public ActionResult AuthenticatedUsers()
     {
         return View();
     }

     [Authorize(Roles = "Admin, Super User")]
     public ActionResult AdministratorsOnly()
     {
         return View();
     }

     [Authorize(Users = "Betty, Johnny")]
     public ActionResult SpecificUserOnly()
     {
         return View();
     }
 }
