Question

How do I get microsoft unity to \'construct\' a list of classes for a given interface type.

Very Simple example:

  List list          


        

Answer 1

You do not need to have the container as parameter, register the concrete types with names as said above, then in the constructor add a array as parameter, IList or generic Enum does not work.

public MyConstructor(IMyType[] myTypes)

Answer 2

If you are using Unity 2 you can use ResolveAll<T>

Container.RegisterType<IShippingInfo,FloridaShippingCalculation>("Florida");
Container.RegisterType<IShippingInfo,NewYorkShippingCalculation>("NewYork");
Container.RegisterType<IShippingInfo,AlaskaShippingCalculation>("Alaska");

IEnumerable<IShippingInfo> infos = Container.ResolveAll<IShippingInfo>();

You have to give a name to every registration because ResolveAll will only return named registrations.
