如何在简单的注入器中注册<Func<Type, IEnumerable<T>>

Question

我正在尝试在我的系统中实现 cqrs，以及如何在简单注入器中注册通用集合？当我尝试运行我的代码时出现异常请使用其他重载之一来注册此类型。

public class Ioc
  {
      public static SimpleInjector.Container Container;

      static Ioc()
      {
          Container = new SimpleInjector.Container();

          Container.Register<IHandleEvent, Handler>(Lifestyle.Transient);
          Container.Register<ICommandsBus, CommandsBus(Lifestyle.Transient);
          Container.Register<IEventsBus, EventsBus>(Lifestyle.Transient);
          Container.Register<Func<Type, IEnumerable<IHandleEvent>>> (Lifestyle.Transient);
      }
  }

//Without any Conatiner working

List<Handler> handlers = new List<Handler>();
          Handler handler = new Handler();
          handlers.Add(handler);
          Func<Type, IEnumerable<IHandleEvent>> func = f => handlers;
          EventsBus eventsBus = new EventsBus(func);
          eventsBus.Publish(new User { Id = 1, Login = "Test" });

// I want something like this
 var bus = Ioc.Container.GetInstance<IEventsBus>();
          bus.Publish(new User { Id = 1, Login = "tt" });

如果您的处理程序是泛型，您可以尝试使用以下逻辑添加它们，首先使用 GetTypesToRegister 获取它们，然后注册为集合

  // assemblies - assemblies with your handlers 

var notificationHandlerTypes = 
    Container.GetTypesToRegister(typeof(IHandleEvent<>), assemblies, new 
        TypesToRegisterOptions
        {
            IncludeGenericTypeDefinitions = true,
            IncludeComposites = false,
        });
Container.Collection.Register(typeof(IHandleEvent<>), notificationHandlerTypes);
