我有一个网站 asp.net MVC 解决方案

我的控制器有 2 个构造函数：一个无参数，一个参数很少。

用于通过带有参数的 ctor 的代码，使用 Unity 容器将它们注入 DI。

我已将我的网站合并到另一个网站。

现在我的控制器通过无参数ctor初始化。

我错过了什么？我的代码：

初始化代码被执行。

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<IDal<Conduit.Mam.MaMDBEntityFramework.MamConfiguration>, MamConfigurationDal>();
            container.RegisterType<IDal<AddServiceBL>, NewService>();

            container.RegisterType<IGeoProdValidator, GeoProdValidator>(new ContainerControlledLifetimeManager());
            container.RegisterType<IConstListsProvider, ConstListsProvider>(new ContainerControlledLifetimeManager());
            container.RegisterType<IEntityToUiConvertor, EntityToUiConvertor>();

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

就像达伦戴维斯指出的那样，您可能缺少一些属性。实际上，Unity 默认采用具有最多参数的构造函数，但要确保您有多个 ctor，您应该使用InjectionConstructor属性装饰所需的一个！希望这可以帮助。亲切的问候
