Estaba mirando este tutorialhttp://asp-umb.neudesic.com/mvc/tutorials/validating-with-a-service-layer--cs sobre cómo ajustar mis datos de validación alrededor de un contenedor.

Sin embargo, me gustaría usar la inyección de dependencia. Estoy usando ninject 2.0

namespace MvcApplication1.Models
{
    public interface IValidationDictionary
    {
        void AddError(string key, string errorMessage);
        bool IsValid { get; }
    }
}

// envoltorio

using System.Web.Mvc;

namespace MvcApplication1.Models
{
    public class ModelStateWrapper : IValidationDictionary
    {

        private ModelStateDictionary _modelState;

        public ModelStateWrapper(ModelStateDictionary modelState)
        {
            _modelState = modelState;
        }

        #region IValidationDictionary Members

        public void AddError(string key, string errorMessage)
        {
            _modelState.AddModelError(key, errorMessage);
        }

        public bool IsValid
        {
            get { return _modelState.IsValid; }
        }

        #endregion
    }
}

// controlador

private IProductService _service;

public ProductController() 
{
    _service = new ProductService(new ModelStateWrapper(this.ModelState),
        new ProductRepository());
}

// capa de servicio

private IValidationDictionary _validatonDictionary;
private IProductRepository _repository;

public ProductService(IValidationDictionary validationDictionary,
    IProductRepository repository)
{
    _validatonDictionary = validationDictionary;
    _repository = repository;
}

public ProductController(IProductService service)
{
    _service = service;
}
