With the new MVC Attribute routing, I know you can assign multiple Route attributes to a single ActionResult, but I am looking for a way to do the same at the RoutePrefix level. I have a controller which, in every action, should be accessible by three routes:
/Games/{Title}/Characters/{Route}
/Books/{Title}/Characters/{Route}
/Cinema/{Title}/Characters/{Route}
I tried putting three individual RoutePrefix attributes, but I get the error Deuplace RoutePrefix attribute. If I try to use a comma-separated list, I get Best override method for does not contain a constructor that takes 3 arguments.
Is it possible to set up a RoutePrefix so that it takes the three routes I want for my controller?
Running a bunch of tests I found out that I can just add 3 Route attributes to the controller level and it works the way I want.
Edit: a better way to do it I found was using the regex match method
[RoutePrefix("{Type:regex(Games|Cinema|Books)}/{SectionRoute}/Character/")]
