当关注点不是横切时，Castle Project'的DynamicProxy如何使代码更容易维护?

不确定我是否正确命名它(即嵌套接口实现)。然而，我不明白使用动态代理比嵌套接口实现有什么好处。动态代理如何比下面的示例代码更好?下面的示例代码是否在某种程度上比DynamicProxy中使用的拦截器模式更有限制?

我理解什么是横切关注点，以及DynamicProxy如何使维护这些情况变得更容易。日志异常之类的事情与实际执行的代码是独立的。这个示例在本质上不像日志示例那样具有普遍性。吃是怎么饼干你吃饼干。当你应该吃时，它不应该与有关。一个不那么做作的例子是查询服务，它决定是否应该调用使用本地存储的实现，还是调用对特定查询进行网络调用的实现。基于它是否在总线上收到了本地存储中包含的项更新的消息。在这种情况下使用DynamicProxy拦截器对代码维护有什么好处?

    IHaveCookies _;
    public SmellService(IHaveCookies implementation) {
        _ = implementation;
    }

        Console.WriteLine("Smelling cookie");
        // intercept call to Eat and don't call it if it smells like poo
        return c.SmellsLike == SmellsLike.Poo
            ? c
            : _.Eat(c);
    }
    // shows that i'm not intercepting this call
    void OtherOperation(Cookie c) {
        // do nothing
        _.OtherOperation(c);
    }
}
//This is the actual service implementation
public class EatService : IHaveCookies {
    public Cookie Eat(Cookie c) {
        Console.WriteLine("Eating cookie");
        var whatsLeft = NomNomNom(c);
        return whatsLeft;
    }
    Cookie NomNomNom(Cookie c) {
        c.Size--;
        return c;
    }
    public void OtherOperation(Cookie c) {
        // do something else

   // shor program that uses windsor to wire up the interfaces
class Program {
    static void Main(string[] args) {
        var container = new WindsorContainer();
        container.Register(
            // interface implementation that is actually given when
            // container.Resolve is called
            Component.For<IHaveCookies>().ImplementedBy<SmellService>().Named("Smell"),
            // wiring up actual service implementation      
            Component.For<IHaveCookies>().ImplementedBy<EatService>().Named("Eat"),
            // this injects the interceptor into the actual service implementation
            Component.For<SmellService>().ServiceOverrides(ServiceOverride.ForKey("implementation").Eq("Eat")));

        // example usage
        var yummy = new Cookie { Size = 2, SmellsLike = SmellsLike.YummyCookie };
        var poo = new Cookie { Size = 2, SmellsLike = SmellsLike.Poo };
