Getting All Controllers and Actions names in C#

Question

Is it possible to list the names of all controllers and their actions programmatically?

I want to implement database driven security for each controller and action. As a developer, I know all controllers and actions and can add them to a database table, but is there any way to add them automatically?

Answer 1

The following will extract controllers, actions, attributes and return types:

Assembly asm = Assembly.GetAssembly(typeof(MyWebDll.MvcApplication));

var controlleractionlist = asm.GetTypes()
        .Where(type=> typeof(System.Web.Mvc.Controller).IsAssignableFrom(type))
        .SelectMany(type => type.GetMethods(BindingFlags.Instance | BindingFlags.DeclaredOnly | BindingFlags.Public))
        .Where(m => !m.GetCustomAttributes(typeof( System.Runtime.CompilerServices.CompilerGeneratedAttribute), true).Any())
        .Select(x => new {Controller = x.DeclaringType.Name, Action = x.Name, ReturnType = x.ReturnType.Name, Attributes = String.Join(",", x.GetCustomAttributes().Select(a => a.GetType().Name.Replace("Attribute",""))) })
        .OrderBy(x=>x.Controller).ThenBy(x => x.Action).ToList();

If you run this code in linqpad for instance and call

controlleractionlist.Dump();

you get the following output:
