webapi multiple methods in MapHttpRoute

Using route annotations in asp.net core I can do the following easily enough

[HttpGet("ByID/{id}")]
public int GetByID(int id)
{
    return 5;
}

[HttpGet("ByName/{id}")]
public string GetByName(string name)
{
    return "neil";
}

However, with the same methods in the controller how do you do it using the non-annotation way in the WebApiConfig file (i.e. .net framework), i.e. what do I add to the below to make it work for the above example.

config.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

As a bonus, can somebody tell me how I would have the same URL map to two GET items differentiated only by type, e.g.

[HttpGet("{id}")]
[HttpGet("{name}")]

where one is an integer and one is a string - in other words the same as the above but without having to specify two separate url segments (ByID, ByName)?

You can use route constraints to differentiate the actions for the same path.

[RoutePrefix("api/somepath")]
public class MyController : ApiController {

    //Matches GET api/somepath/5
    [HttpGet]
    [Route("{id:int}")]
    public int GetByID(int id) {
        return id;
    }

    //Matches GET api/somepath/neil
    [HttpGet]
    [Route("{name}")]
    public string GetByName(string name) {
        return name;
    }
}

Note the default is string which is why there is none on the second action.
