アクションフィルターでUnityとasp.net mvcを使ってプロパティーインジェクションを実行するには？

Question

プロパティインジェクションを使用したアクションフィルタで依存性インジェクションを実行しようとしています。フィルタの依存関係を自動的に設定する方法を理解できません。ここに私がこれまで持っていたコードがあります。

public class UnityActionInvoker : ControllerActionInvoker 
{ 
    IUnityContainer container; 

    public UnityActionInvoker(IUnityContainer container) { 
     this.container = container; 
    } 

    protected override ActionExecutedContext InvokeActionMethodWithFilters(ControllerContext controllerContext, IList<IActionFilter> filters, ActionDescriptor actionDescriptor, IDictionary<string, object> parameters) { 
     foreach (var filter in filters) { 
      // HELP: dependency injection on all marked filter properties 
     } 

     return base.InvokeActionMethodWithFilters(controllerContext, filters, actionDescriptor, parameters); 
    } 
} 

public class UnityControllerFactory : DefaultControllerFactory 
{ 
    IUnityContainer container; 

    public UnityControllerFactory(IUnityContainer container) { 
     this.container = container; 
    } 

    protected override IController GetControllerInstance(Type controllerType) { 
     Controller controller = null; 

     if (controllerType != null) { 
      if (!typeof(IController).IsAssignableFrom(controllerType)) { 
       throw new ArgumentException(string.Format("Type requested is not a controller: {0}", controllerType.Name), "controllerType"); 
      } 

      controller = container.Resolve(controllerType) as Controller; 
      controller.ActionInvoker = new UnityActionInvoker(container); 
     } 

     return controller; 
    } 
} 

public class AccessFilterAttribute : FilterAttribute, IActionFilter 
{ 
    [Dependency] 
    public IUserRepository UserRepository { get; set; } 

    public void OnActionExecuting(ActionExecutingContext filterContext) { 
     throw new NotImplementedException(); 
    } 

    public void OnActionExecuted(ActionExecutedContext filterContext) { 
     throw new NotImplementedException(); 
    } 
}

答えは次のとおりです。

public class UnityActionInvoker : ControllerActionInvoker 
{ 
    IUnityContainer container; 

    public UnityActionInvoker(IUnityContainer container) { 
     this.container = container; 
    } 

    protected override ActionExecutedContext InvokeActionMethodWithFilters(ControllerContext controllerContext, IList<IActionFilter> filters, ActionDescriptor actionDescriptor, IDictionary<string, object> parameters) { 
     foreach (var filter in filters) { 
      container.BuildUp(filter.GetType(), filter); 
     } 

     return base.InvokeActionMethodWithFilters(controllerContext, filters, actionDescriptor, parameters); 
    } 
}
