问题
The project I'm starting to work at will have several dozens of controllers, so it would be nice to structure them into logical directories and respective namespaces, like "Controllers/Admin/", "Controllers/Warehouse/Supplies/", etc.
Does ASP.NET MVC support nested controller directories and namespacing? How do I manage routes to those controllers?
回答1:
You can put the controllers anywhere; routes do not depend on where a controller is stored. It will be able to find any class that implements IController within your application.
I usually keep my controllers in a separate project, f.ex a MyProject.Frontend project, alongisde a MyProject.Frontend.Application project which is the actual entrypoint web project with the views etc.
