Register open generics with precedence

Question

Is it possible to use unity like so:

container.Register(typeof(IMyType<car>), typeof(MyType1<car>));
container.Register(typeof(IMyType<>), typeof(MyType2<>));

.. so that when I try to resolve IMyType<car> I get a MyType1<car>... but when I try to resolve IMyType<bus> I get MyType2<bus> ? Or perhaps another way to do the same thing so that a defined generic takes precedence over an open generic?

Answer 1

Yes, you can do exactly that:

IUnityContainer container = new UnityContainer();

container.RegisterType(typeof(IMyType<Car>), typeof(MyType1<Car>));
container.RegisterType(typeof(IMyType<>), typeof(MyType2<>));

// Returns MyType1<Car>:
IMyType<Car> car = container.Resolve<IMyType<Car>>();

// Returns MyType2<Bus>:
IMyType<Bus> bus = container.Resolve<IMyType<Bus>>();
