Web.Api routing additional parameters to route

Question

How can I add additional parameters to web api route? I want to add one parameter to default route and support versioning my api, sth like this: api/{version}/{controller}/{action}/{id}

I know that {controller} is mapped automatically with controller name and {action} metho name, but what or how could to {version} mapped?

p.s. yeah, sound very weird question, but...

You would need to implement a new controller selector. There are open source implementations. — Darrel Miller

In your WebApiConfig.cs , you need to have -

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{version}/{controller}/{action}/{id}",
            defaults: new { version = 1, id = RouteParameter.Optional }
        );

And when you execute the values controler getjson action -

    public string GetJson(string id)
    {
        return "me";
    }

You get following output -

If you want to version your WebAPI endpoints, then use this namespaces approach. Alternatively, you can also use Http header approach. Or else simply route approach.
