此對象MVC4

Question

這個問題沒有定義參數的構造函數已經問這麼多時間，也試圖創造默認的構造器爲我的模型類，但仍然即時得到error.below是我的代碼行，我想知道，如果有人可以幫助我修復我的代碼..

public class RecordController: Controller 
    { 
     private readonly IRecord _DataService = null; 

     public RecordController(IRecord dataService) 
     { 
      _DataService = dataService ; 
     } 

     [HttpGet] 
     public ActionResult TestRecord() 
     { 
      return View(); 
     } 

     [HttpPost] 
     public ActionResult TestRecord(TestRecordModel model) 
     {   

      return View(); 
     } 

    } 

---

下面是我TestRecordModel類

public class TestRecordModel 
     { 
      [Required] 
      [Display(Name = "UserNo #:)] 
      public string UserNo { get; set; } 

     } 

下面是我的引導程序，WindsorControllerActivator的d ControllerInstaller

public class Bootstrapper 
    { 
     #region Properties 

     public static IWindsorContainer Container { get; private set; } 

     #endregion 

     /// <summary> 
     /// Initialises this instance. 
     /// </summary> 
     public static void RegisterAllTypes() 
     { 
      // adds and configures all components using WindsorInstallers from executing assembly. 
      Container = new WindsorContainer().Install(FromAssembly.InThisApplication()); 

      Container.Register(Component.For<IViewEngine>().ImplementedBy<RazorViewEngine>()); 
      Container.Register(Component.For<IControllerFactory>().ImplementedBy<WindsorControllerFactory>()); 
      Container.Register(Component.For<IControllerActivator>().ImplementedBy<WindsorControllerActivator>()); 
      Container.Register(Component.For<IHttpControllerActivator>().ImplementedBy<WindsorHttpControllerActivator>()); 

      DependencyResolver.SetResolver(new WindsorDependencyResolver(Container.Kernel)); 

      GlobalConfiguration.Configuration.DependencyResolver = new WindsorHttpDependencyResolver(Container.Kernel); 
     } 

     public static void RegisterType<TContract, TImplementation>(params KeyValuePair<string, string>[] parameters) 
      where TContract : class 
      where TImplementation : TContract 
     { 
      var dependencies = parameters 
       .Select(parameter => Parameter.ForKey(parameter.Key).Eq(parameter.Value)) 
       .Select(dummy => (Dependency)dummy).ToArray(); 

      Container.Register(Component.For<TContract>() 
            .ImplementedBy<TImplementation>() 
            .DependsOn(dependencies)); 
     } 

     public static TContract Resolve<TContract>() 
     { 
      return Container.Resolve<TContract>(); 
     } 

     /// <summary> 
     /// Releases unmanaged and - optionally - managed resources. 
     /// </summary> 
     public static void Dispose() 
     { 
      // clean up, application exits. 
      if (Container != null) 
       Container.Dispose(); 
     } 
    }

Answer 1

也許如果您嘗試使用序列化或Activator.CreateInstance（T），那麼你將獲得有關參數的構造函數的錯誤。

Answer 2

你得到的錯誤是標準的錯誤時，MVC框架創建一個控制器。我認爲你註冊/ bootstrapper沒有被正確調用。 設置斷點內WindsorControllerActivator，看它是否被調用。
