Web API - Multiple parameters as /param1/param2/param3/ not working

I have a an ASP.NET Web API project where I have a single method in my controller as such ..

public IHttpActionResult MyMethod(int param1, int param2, int param3)
{
  var theSum = param1 + param2 + param3;
  return Ok(theSum);
}

I have the following route in RouteConfig.cs

routes.MapRoute(
  name: "MyRoute",
  url: "api/{controller}/{action}/{param1}/{param2}/{param3}",
  defaults: new { controller = "MyController", action = "MyRoute", param1 = UrlParameter.Optional, param2 = UrlParameter.Optional, param3 = UrlParameter.Optional }
  );

When I call the API with the following URL everything works as expected ..

http://localhost/api/mycontroller/mymethod?param1=2&param2=4&param3=6

Yet when I try to call the API as follows I get a 404 - The resource cannot be found error.

http://localhost/api/mycontroller/mymethod/2/4/6/

any idea why? I thought I had the route setup properly and since the parameters are .NET primitives I though I could pass them as param1/param2/param3

Are you using MVC5? If so I'd suggest using the Route() attribute instead the routes collection, for me at least it is easier to manage. I was able to get this working with your sample using that approach.

[Route("api/values/MyMethod/{param1}/{param2}/{param3}")]
[HttpGet]
public IHttpActionResult MyMethod(int param1, int param2, int param3)
{
    var theSum = param1 + param2 + param3;
    return Ok(theSum);
}

And then calling it via http://localhost/api/values/mymethod/2/4/6 properly returned 12.
