[ActionName("Enumerate")]
public ViewResult List() {
return View("Result", new Result {
ControllerName = "Customer",
ActionName = "List"
});
}
}
}
[NonAction]
public ActionResult MyAction() {
return View();
}
The MyAction method in the listing will not be considered as an action method, even though it meets all of the criteria that
the invoker looks for. This is useful for ensuring that you do not expose the workings of your controller classes as actions. Of
course, normally such methods should simply be marked private, which will prevent them from being invoked as actions;
however, [NonAction] is useful if for some reason you must mark such a method as public. Requests for URLs that
target NonAction methods will generate 404—Not Found errors, as shown in Figure 19-7.

Creating a Custom Action Method Selector
Action method selectors are derived from the ActionMethodSelectorAttribute class, which is shown in Listing
