Вот мое сообщение об ошибке, которое отображается, когда я просматриваю: ../api/User«RavenReader.Web.Controllers.UserController» не имеет конструктор по умолчанию

по http://www.peterprovost.org/blog/2012/06/19/adding-ninject-to-web-api/ этот блог я организовал мой NinjectDependencyScope класс, NinjectDependencyResolver класс и NinjectWebCommon следующим образом:
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);
}
}
public class NinjectDependencyResolver : NinjectDependencyScope, IDependencyResolver
{
private IKernel kernel;
public NinjectDependencyResolver(IKernel kernel)
: base(kernel)
{
this.kernel = kernel;
}
public IDependencyScope BeginScope()
{
return new NinjectDependencyScope(kernel.BeginBlock());
}
}
public static class NinjectWebCommon
{
private static readonly Bootstrapper bootstrapper = new Bootstrapper();
/// <summary>

public static void Start()
{
DynamicModuleUtility.RegisterModule(typeof(OnePerRequestHttpModule));
DynamicModuleUtility.RegisterModule(typeof(NinjectHttpModule));
bootstrapper.Initialize(CreateKernel);
}

public static void Stop()
{
bootstrapper.ShutDown();
}
/// <summary>

public static IKernel CreateKernel()
{
var kernel = new StandardKernel();
kernel.Bind<Func<IKernel>>().ToMethod(ctx =>() => new Bootstrapper().Kernel);
kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();
RegisterServices(kernel);
GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel);
return kernel;
}
/// <summary>

private static void RegisterServices(IKernel kernel)

Я использую Visual Studio 2013 Ninject Для MVC-3
ли Вы, помните, установка этого ' DependencyResolver' для вашего 'WebApiConfig'? Обычно это делается в 'WebApiConfig.cs' – cvbarros
Спасибо за ваш ответ. Я сделал тест Apicontroller в моем же проекте, где он работает нормально. Код контроллера является открытым классом TestController: ApiController { private readonly ITest _test; public TestController (тест ITest) { _test = test; } public string Get() { return_test.Имя; } } и внутри NinjectWebCommon.cs Я связываю следующее: kernel.Bind() .To () ;. но когда я работаю с моим реальным контроллером, он возвращает мне ошибку метода конструктора по умолчанию. –
