温莎城堡注册实现特定接口的所有组件 [英] castle windsor register all components implementing specific interface

问题描述

我有多个实现IPollingService接口的组件，我想按惯例将它们全部注册。顺便说一句，我没有在容器中看到任何组件注册，而且似乎无法解决它们。知道吗？

I have multiple components implementing IPollingService interface and i'd like to register them all by convention. By the way i don't see any component registered in the container and i cannot seem to resolve them. Any idea?

我尝试了以下操作，但无法解决：

I tried the following but i cannot resolve them:

    public class PollingServicesInstaller : IWindsorInstaller
    { 
        public void Install( IWindsorContainer container, IConfigurationStore store )
        {
            var registrations = Classes.FromThisAssembly()
                .BasedOn<IPollingService>().WithServiceBase().AllowMultipleMatches();

            container.Register( registrations );
        }
    }

   static void Main( string[] args )
   {
        var container = new Castle.Windsor.WindsorContainer();
        container.Install( new PollingServicesInstaller() );

        var pollingServices = container.ResolveAll<IPollingService>();
        //pollingServices is empty at this point but i got several implementations in this assembly
   }

  public class ServiceMock1 : IPollingService
    {
        public int PollingInterval { get; set; }
        public bool Enabled { get; set; }

        public ServiceMock1()
        {
            this.PollingInterval = 3000;
        }

        public void Run()
        {
            Console.WriteLine( Thread.CurrentThread.ManagedThreadId );
            Console.WriteLine( "doing stuff " + this.PollingInterval );
        }
    }

从屏幕截图中可以看到0个实现已加载。

As you can see from the screenshot 0 implementations are loaded.

我还注意到，如果我尝试通过这种方式运行安装程序，则CastleWindsor找不到我的安装程序：

I also noticed that CastleWindsor do not find my installer if i try to run installers this way:

 container.Install( FromAssembly.This() );

推荐答案

我的类和接口都是公共的，但在Program中声明类，默认情况下是内部类，因此不会被发现。 [查看问题代码的屏幕截图]

My classes and interfaces are all public but declared inside Program class, that is internal by default and so are not discovered. [See the screenshot of the code in the question]

我认为这是违反直觉的，但不一定是Castle.Windsor问题。

I think this is counterintuitive but is not necessarily a Castle.Windsor problem.

Castle.Windsor的行为应该有所不同吗？

Should Castle.Windsor behave somewhat differently?

为什么允许在内部类中声明公共类？
