.NET MVC: Counting Action methods in web application

Question

We've got a huge ASP.NET MVC 3 application. We need to count how many public methods we have in classes where currentClass is System.Web.Mvc.Controller.

Any class that meets this criteria will have a base namespace of 'AwesomeProduct.Web', but there's no guarantee beyond that what namespace these classes may fall under, or how many levels of depth there are.

What's the best way to figure this out?

Answer 1

Some reflection and LINQ like this should do it

var actionCount = typeof(/*Some Controller Type In Your MVC App*/)
                    .Assembly.GetTypes()
                    .Where(t => typeof(Controller).IsAssignableFrom(t))
                    .Where(t => t.Namespace.StartsWith("AwesomeProduct.Web"))
                    .SelectMany(t => t.GetMethods(BindingFlags.Public | BindingFlags.Instance))
                    .Where(m => typeof(ActionResult).IsAssignableFrom(m.ReturnType))
                    .Where(m => !m.IsAbstract)
                    .Where(m => m.GetCustomAttribute<NonActionAttribute>() == null)
                    .Count();

This does not cater for async controller actions.
