WebApi - Bind from both Uri and Body

Question

Is it possible to bind a model from both the Uri and Body?

For instance, given the following:

routes.MapHttpRoute(
    name: \"API Default\",
    rou

Alright, I came up with a way to do it. Basically, I made an action filter which will run after the model has been populated from JSON. It will then look at the URL parameters, and set the appropriate properties on the model. Full source below:

using System.ComponentModel;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Reflection;
using System.Web.Http.Controllers;
using System.Web.Http.Filters;


public class UrlPopulatorFilterAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(HttpActionContext actionContext)
    {
        var model = actionContext.ActionArguments.Values.FirstOrDefault();
        if (model == null) return;
        var modelType = model.GetType();
        var routeParams = actionContext.ControllerContext.RouteData.Values;

        foreach (var key in routeParams.Keys.Where(k => k != "controller"))
        {
            var prop = modelType.GetProperty(key, BindingFlags.IgnoreCase | BindingFlags.Instance | BindingFlags.Public);
            if (prop != null)
            {
                var descriptor = TypeDescriptor.GetConverter(prop.PropertyType);
                if (descriptor.CanConvertFrom(typeof(string)))
                {
                    prop.SetValueFast(model, descriptor.ConvertFromString(routeParams[key] as string));
                }
            }
        }
    }
}
