二 使用Ninject

 public interface IStudent
    {
        string GetName();
    }

 public class Student : IStudent
    {
        public string GetName()
        {
            return "ligenyun";
        }
    }

 public class NinjectControllerFactory : DefaultControllerFactory
    {
        private IKernel ninjectKernel;

        public NinjectControllerFactory()
        {
            ninjectKernel = new StandardKernel();
            AddBindings();
        }

        private void AddBindings()
        {
            ninjectKernel.Bind<IStudent>().To<Student>();
        }

        protected override IController GetControllerInstance(System.Web.Routing.RequestContext requestContext, Type controllerType)
        {
            return controllerType == null ? null : (IController)ninjectKernel.Get(controllerType);
        }
    }

            ControllerBuilder.Current.SetControllerFactory(new NinjectControllerFactory());
        }
    }
}
