Route attribute routing with query strings when there are multiple routes

Question

I have this:

[HttpGet]
[Route(\"Cats\")]
public IHttpActionResult GetByCatId(int catId)

[HttpGet]
[Route(\"Cats\")]
public IHttpActionResult GetByName(strin         


        

Answer 1

Try applying constraints on attribute routing.

[HttpGet]
[Route("Cats/{catId:int}")]
public IHttpActionResult GetByCatId(int catId)

[HttpGet]
[Route("Cats/{name}")]
public IHttpActionResult GetByName(string name)
