WebAPI Controller Names with Underscores

Question

WebAPI has a naming convention "FooController" for controller names. This is similar to ASP.NET MVC. Our codebase uses underscores to separate words in identifier named, eg "Foo_Bar_Object". In order for the controller names to follow this convention, we need a way to name our controllers "Foo_Controller".

Basically, we don't want URL routes to look like "oursite.com/api/foo_/", and we don't want to have to make exceptions everywhere for the underscore (eg route config, names of view folders, etc). To do this in MVC, we do:

Global.asax

protected void Application_Start() {

    ...

    ControllerBuilder.Current.SetControllerFactory(new Custom_Controller_Factory());
}

Custom_Controller_Factory.cs

public class Custom_Controller_Factory : DefaultControllerFactory
{
    protected override Type GetControllerType(RequestContext request_context, string controller_name)
    {
        return base.GetControllerType(request_context, controller_name + "_");
    }
}

This seems to completely take care of the problem all in once place in MVC. Is there a way to do the same for WebAPI? I've heard rumor of a DefaultHttpControllerFactory but I can't find it anywhere.

I think DefaultHttpControllerSelector is what you are looking for.

class CustomHttpControllerSelector : DefaultHttpControllerSelector {

   public CustomHttpControllerSelector(HttpConfiguration configuration) 
      : base(configuration) { }

   public override string GetControllerName(HttpRequestMessage request) {

      IHttpRouteData routeData = request.GetRouteData();
      string controller = (string)routeData.Values["controller"]

      return controller + "_";
}

Global.asax

GlobalConfiguration.Configuration.Services.Replace(typeof(IHttpControllerSelector), new sh_Custom_Http_Controller_Selector(GlobalConfiguration.Configuration));
