MVC Rest API - Unable to get Collection in json parameter

问题

I'm trying to send this json to my controller

{  
   "Name":"Ford Focus",
   "CarProperties":[  
      {
         "Name":"Airbag"
      }
   ]
}

As you see there is a Collection named as CarProperties. I want to handle this collection in my Controller function. But getting null.

Controller

public class TestController : ApiController
{

    public CarViewModel PostCar(CarViewModel car)
    {
        //Here is the error
        // Output is : {"Name":"Ford Focus"} so, car.CarProperties has come as null
        return car;
    }

}

View Models

public class CarPropertyViewModel {
    public string Name;
}

public class CarViewModel
{
    public string Name;
    public List<CarPropertyViewModel> CarProperties { get; set; }
}

What I am doing wrong?
