Question

I have base interface IBaseModel with many descendants (ex. IContactModel : IBaseModel;, IRelationModel : IBaseModel; etc.) and objects what implements this interfaces.

All this descendants interfaces is registered in Unity container.

How can I resolve all my objects what is descendant from IBaseModel?

Answer 1

var types = Container
  .Registrations
  .Where(x => typeof (IBaseModel).IsAssignableFrom(x.RegisteredType))
  .Select(x => x.RegisteredType)
  .ToList();

var result = types
  .Select(x => (IBaseModel) Container.Resolve(x.UnderlyingSystemType))
  .ToList();
