C# Question

Getting All Controllers and Actions names in C#

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

You can use reflection to find all Controllers in the current assembly, and then find their public methods that are not decorated with the NonAction attribute.

Assembly asm = Assembly.GetExecutingAssembly();

asm.GetTypes()
    .Where(type=> typeof(Controller).IsAssignableFrom(type)) //filter controllers
    .SelectMany(type => type.GetMethods())
    .Where(method => method.IsPublic && ! method.IsDefined(typeof(NonActionAttribute)));
