爲什麼叫控制器的參數的構造函數，而不是一個與我有一個網站，asp.net MVC解決方案</p> <p>我的控制器有2個構造函數的參數

Question

最大數：一個無參數和一個與幾個參數。

用於使用參數穿過ctor的代碼，使用Unity容器將它們注入到DI中。

我已將我的網站合併到另一個網站中。

現在我的控制器通過無參數ctor初始化。

我錯過了什麼？ 我的代碼：

執行初始化程序代碼。

public static class Initializer 
{ 
    private static bool isInitialize; 
    private static readonly object LockObj = new object(); 
    private static IUnityContainer defaultContainer = new UnityContainer(); 

    static Initializer() 
    { 
     Initialize(); 
    } 

    public static void Initialize() 
    { 
     if (isInitialize) 
      return; 

     lock (LockObj) 
     { 
      IUnityContainer container = defaultContainer; 

      //registering Unity for web API 
      GlobalConfiguration.Configuration.DependencyResolver = new Unity.WebApi.UnityDependencyResolver(container); 
      //registering Unity for MVC 
      DependencyResolver.SetResolver(new UnityDependencyResolver(container)); 

      container.RegisterType<ICritieriaLoader, CritieriaLoader>(); 
      container.RegisterType<IAppsLoader, AppsLoader>(); 
      container.RegisterType<ISaveTestToBD, SaveTestToDB>(); 
      container.RegisterType<ITestOperations, TestOperations>(); 


      container.RegisterType<IServicesManager, ServicesManager>(); 
      container.RegisterType<IMamConfigurationManager, MamConfigurationsManager>(); 
      container.RegisterType<IAppsDataManager, AppsDataManager>(); 
      container.RegisterType<IMamConfiguration_V1Manager, MamConfiguration_V1Manager>(); 
      container.RegisterType<ICtidProd_V1Manager, CtidProd_V1Manager>(); 
      container.RegisterType<ICtidsAliasManager, CtidsAliasManager>(); 


      container.RegisterType<IDalFactory, DalFactory>(); 
      container.RegisterType<IDal<AppsDataBl>, AppsDataDal>(); 
      container.RegisterType<IApplicationLogger, Log4NetLogger>(); 
      container.RegisterType<IDal<MamConfigurationBL>, MamConfigurationBlDal>(); 
      container.RegisterType<IDal<Conduit.Mam.MaMDBEntityFramework.MamConfiguration>, MamConfigurationDal>(); 
      container.RegisterType<IDal<AddServiceBL>, NewService>(); 


      container.RegisterType<IAlias_V1UiToEfConvertor, Alias_V1UiToEfConvertor>(new ContainerControlledLifetimeManager()); 
      container.RegisterType<IMamConfiguration_V1UiToEfConvertor, MamConfiguration_V1UiToEfConvertor>(new ContainerControlledLifetimeManager()); 
      container.RegisterType<ICtidProdValidator, CtidPRodValidator>(new ContainerControlledLifetimeManager()); 
      container.RegisterType<IGeoProdValidator, GeoProdValidator>(new ContainerControlledLifetimeManager()); 
      container.RegisterType<IConstListsProvider, ConstListsProvider>(new ContainerControlledLifetimeManager()); 
      container.RegisterType<IEntityToUiConvertor, EntityToUiConvertor>(); 

      if (!isInitialize) 
      { 
       isInitialize = true; 
      } 
     } 
    } 
} 

。

protected void Application_Start() 
    { 
     Log.Application.Warn("Application started", "Application started"); 

     WebApiConfig.Configure(GlobalConfiguration.Configuration); 

     AreaRegistration.RegisterAllAreas(); 

     FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); 

     RouteConfig.RegisterRoutes(RouteTable.Routes); 

     BundleConfig.RegisterBundles(BundleTable.Bundles); 

     Initializer.Initialize();

像達倫·戴維斯指出你可能缺少的某些屬性。實際上，默認情況下Unity會使用參數最多的構造函數，但要確保如果您有多個ctor，則應使用InjectionConstructor屬性修飾所需的值。 希望這有助於。 親切的問候
