Dependency injection 如何注入EmailMessageService

我的服务注射有问题。我有一个iSetting服务。我正在测试注册我的应用程序和使用电子邮件确认

因此，在从IIdentialMessageService继承的EmailMessageService类中

我在为国际奥委会使用团结。我已经在unity config注册了ISettingService，如下所示

.RegisterType<ISettingService, SettingService>()

EmailMessageService类在Startup.Auth时实例化

            var manager =
            new ApplicationUserManager(
                new ApplicationUserStore(context.Get<DataContext>()));
            ...
            manager.EmailService = new EmailMessagingService();

在EmailMessageService中。

好的，我不知道发生了什么，但通过更改UnityMVActivator的启动方法，如下面的固定方法

public static void Start()
    {
        var container = ContainerManager.GetConfiguredContainer();
        UnityConfig.RegisterTypes(container);

        FilterProviders.Providers.Remove(FilterProviders.Providers.OfType<FilterAttributeFilterProvider>().First());
        FilterProviders.Providers.Add(new UnityFilterAttributeFilterProvider(container));

        DependencyResolver.SetResolver(new UnityDependencyResolver(container));

        var assemblies = AppDomain.CurrentDomain.GetAssemblies();

        try
        {
            //http://stackoverflow.com/questions/699852/how-to-find-all-the-classes-which-implement-a-given-interface
            foreach (var assembly in assemblies)
            {
                var instances = from t in assembly.GetTypes()
                                where t.GetInterfaces().Contains(typeof(IDependencyRegister))
                                         && t.GetConstructor(Type.EmptyTypes) != null
                                select Activator.CreateInstance(t) as IDependencyRegister;

                foreach (var instance in instances.OrderBy(x => x.Order))
                {
                    instance.Register(container);
                }
            }
        }
        catch (ReflectionTypeLoadException ex)
        {

            System.Text.StringBuilder sb = new System.Text.StringBuilder();
            foreach (Exception exSub in ex.LoaderExceptions)
            {
                sb.AppendLine(exSub.Message);
                System.IO.FileNotFoundException exFileNotFound = exSub as System.IO.FileNotFoundException;
                if (exFileNotFound != null)
                {
                    if (!string.IsNullOrEmpty(exFileNotFound.FusionLog))
                    {
                        sb.AppendLine("Fusion Log:");
                        sb.AppendLine(exFileNotFound.FusionLog);
                    }
                }
                sb.AppendLine();
            }
            string errorMessage = sb.ToString();

            throw new Exception(errorMessage, ex);
            //Display or log the error based on your application.
        }

foreach（程序集中的变量程序集）

var instances=来自assembly.GetTypes（）中的t

设置服务

是

私有的

，这意味着从任何合理组合引擎的角度来看，该属性都不存在。除此之外，我不清楚为什么不能使用构造函数注入。我公开了它，但我得到了同样的错误。如果我使用构造函数inject

manager.EmailService=newemailMessagingService（）我需要给这行指定参数。我真的不知道该怎么做。
