C# 使用windsor安装时解决的类型访问问题,c#,castle-windsor,C#,Castle Windsor,我有大量依赖于看门狗组件的类。我向watchdog实例添加了对dependent类的引用 目前，我使用以下代码来实现这一点 class MyClass { public MyClass(IWatchDog watchDog) { watchDog.WatchingType = typeof(MyClass); } } 我的安装程序： class IoC: IWindsorInstaller { public void Install(

我有大量依赖于看门狗组件的类。我向watchdog实例添加了对dependent类的引用

目前，我使用以下代码来实现这一点

   class MyClass {
      public MyClass(IWatchDog watchDog) {
        watchDog.WatchingType = typeof(MyClass);
      }
   }
我的安装程序：

class IoC: IWindsorInstaller {
    public void Install(IWindsorContainer container, IConfigurationStore store) {
        container.Register(Component.For<MyClass>());
        container.Register(Component.For<IWatchDog>().ImplementedBy<WatchDogService>());
    }
}

class-IoC:IWindsorInstaller{
public void安装（IWindsorContainer、IConfigurationStore）{
container.Register（Component.For（））；
container.Register（Component.For（）.ImplementedBy（））；
}
}
是否可以让安装人员为我执行此任务？以下是我在伪代码中的想法，解析是我想象的方法：

class IoC : IWindsorInstaller {
    public void Install(IWindsorContainer container, IConfigurationStore store) {
        container.Register(Component.For<MyClass>());
        container.Register(
            Component.For<IWatchDog>()
                .ImplementedBy<WatchDogService>()
                .OnResolving<IWatchDog>(
                    new Action((Type typeBeingResolved, IWatchDog instance) =>
                        instance.WatchingType = typeBeingResolved));

    }
}

class-IoC:IWindsorInstaller{
public void安装（IWindsorContainer、IConfigurationStore）{
container.Register（Component.For（））；
集装箱。登记(
用于（）的组件
.由（）实施
.OnResolving(
新操作（（键入typeBeingResolved，IWatchDog实例）=>
instance.WatchingType=typeBeingResolved））；
}
}
因此，在本例中，我想象
typeBeingResolved
将等于
typeof（MyClass）
如果调用
container.Resolve（）
，或者
null
如果有人调用
container.Resolve（）

显然，如果我能够以某种方式访问正在解析的类型的实例，就像在
OnCreate（）
中一样，这也会起作用。

使用自定义工具，您可以将组件的默认激活器更改为您想要的激活器。下面是一个可行的解决方案：

using Castle.MicroKernel.Facilities;

using System.Threading.Tasks; 

namespace ComponentCreater
{
public interface IWatchDogService
{
    Type WatchingType { get; set; }
}

public class WatchDogService : IWatchDogService

}


public class WatchedClassViaConstructor
{
    private readonly IWatchDogService watchDogService;

    public WatchedClassViaConstructor(IWatchDogService watchDogService)
    {
        this.watchDogService = watchDogService;
    }

    public void Print()
    {
        Console.WriteLine(this.watchDogService.WatchingType.Name);
    }
}

public class WatchDogFacility : AbstractFacility
{
    protected override void Init()
    {
        this.Kernel.ComponentModelCreated += Kernel_ComponentModelCreated;
    }

    private void Kernel_ComponentModelCreated(ComponentModel model)
    {
        model.CustomComponentActivator = typeof(WatchedComponentActivator);   
    }
}

public class WatchedComponentActivator : DefaultComponentActivator
{
    public WatchedComponentActivator(ComponentModel model, IKernel kernel, ComponentInstanceDelegate onCreation, ComponentInstanceDelegate onDestruction)
        : base(model, kernel, onCreation, onDestruction)
    {
    }

    protected override object CreateInstance(CreationContext context, ConstructorCandidate constructor, object[] arguments)
    {
        object component = base.CreateInstance(context, constructor, arguments);

        if (arguments != null)
        {
            IWatchDogService watchDogService = arguments.FirstOrDefault(arg => arg is IWatchDogService) as IWatchDogService;
            if (watchDogService != null)
            {
                watchDogService.WatchingType = component.GetType();
            }
        }

        return component;
    }
}

class Program

        container.Register(

                .ImplementedBy<WatchDogService>()
                .LifestyleTransient(),
            Component.For<WatchedClassViaConstructor>()

        WatchedClassViaConstructor obj = container.Resolve<WatchedClassViaConstructor>();
        obj.Print();

这使用了相同的策略，但使用了属性注入。我创建了一个组件模型构造贡献者，以强制castle要求注入IWatchDogServcie，就像是构造函数注入一样。下面是代码：
