Я установил свой проект с помощью Ninject IoC.
Мой проект имеет регулярные контроллеры Asp.Net MVC и контроллеры Web Api. Теперь Ninject работает с Web Api, но Ninject не работает с обычными контроллерами Asp.MVC.
Моя регулярная реализация MVC-контроллера;
public class GalleryController : BaseController
{
public GalleryController(IUow uow)
{
Uow = uow;
}
........
}
Ошибка при использовании с обычным контроллером
An error occurred when trying to create a controller of type 'Web.Controllers.HomeController'. Make sure that the controller has a parameterless public constructor.]
Однако, когда я пытаюсь использовать тот же код с Web Api,, он работает
public class GalleryController : BaseApiController
{
public GalleryController(IUow uow)
{
Uow = uow;
}
......
}
мой интерфейс, который содержит разностные репозитории (шаблон factory)
public interface IUow
{
// Save pending changes to the data store.
void Commit();
//Repositoryries
IRepository<Gallery> Gallery { get; }
IMenuRepository Menus { get; }
}
NinjectDependencyScope class;
public class NinjectDependencyScope : IDependencyScope
{
private IResolutionRoot resolver;
internal NinjectDependencyScope(IResolutionRoot resolver)
{
Contract.Assert(resolver != null);
this.resolver = resolver;
}
public void Dispose()
{
var disposable = resolver as IDisposable;
if (disposable != null)
disposable.Dispose();
resolver = null;
}
public object GetService(Type serviceType)
{
if (resolver == null)
throw new ObjectDisposedException("this", "This scope has already been disposed");
return resolver.TryGet(serviceType);
}
public IEnumerable<object> GetServices(Type serviceType)
{
if (resolver == null)
throw new ObjectDisposedException("this", "This scope has already been disposed");
return resolver.GetAll(serviceType);
}
}
NinjectDependencyResolver класс;

public NinjectDependencyResolver(IKernel kernel)

}
}
Ninject для Global.asax;
public class IocConfig
{
public static void RegisterIoc(HttpConfiguration config)
{
var kernel = new StandardKernel(); // Ninject IoC
//kernel.Load(Assembly.GetExecutingAssembly()); //only required for asp.net mvc (not for webapi)
// These registrations are "per instance request".
// See http://blog.bobcravens.com/2010/03/ninject-life-cycle-management-or-scoping/
kernel.Bind<RepositoryFactories>().To<RepositoryFactories>()
.InSingletonScope();

kernel.Bind<IUow>().To<Uow>();
// Tell WebApi how to use our Ninject IoC
config.DependencyResolver = new NinjectDependencyResolver(kernel);
}
}
