温莎城堡:从xml配置注入服务数组

wex*_*man 2 xml arrays castle-windsor castle inject

我在通过Castle Windsor使用xml配置注入一系列服务时遇到问题。我已经按照链接进行了很好的解释,但是以某种方式它对我不起作用。这是我正在使用的代码:

class Program
{
    static void Main(string[] args)
    {
        IWindsorContainer container = new WindsorContainer();
        container.Install(Castle.Windsor.Installer.Configuration.FromAppConfig());

        var consumer = container.Resolve<Consumer>();
    }
}

public class Consumer
{
    public Consumer(IFoo[] foos)
    {
        foreach (IFoo foo in foos)
            foo.Foo();
    }
}

public interface IFoo
{
    void Foo();
}

public class Foo1 : IFoo
{
    public void Foo() { }
}

public class Foo2 : IFoo
{
    public void Foo() { }
}

这是app.config:

<castle>
  <components>
     <component id="Foo1" service="Test.IFoo, Test" type="Test.Foo1, Test" />
     <component id="Foo2" service="Test.IFoo, Test" type="Test.Foo2, Test" />

     <component id="Consumer" service="Test.Consumer, Test">
        <parameters>
           <foos>
              <array>
                 <item>${Foo1}</item>
                 <item>${Foo2}</item>
              </array>
           </foos>
        </parameters>
     </component>
  </components>
</castle>

奇怪的是,我得到的错误如下:

Can't create component 'Test.Consumer' as it has dependencies to be satisfied.
'Test.Consumer' is waiting for the following dependencies:
- Service 'Test.IFoo[]' which was not registered.

为什么期望IFoo []作为服务?这有任何意义吗?或者也许我所指的链接在当前版本的Windsor(我在3.1.0上)上不再起作用?

再次回答我自己的问题(对不起;-):

事实证明,解决方案非常简单-一旦知道。将ArrayResolver添加为子解析器不仅使此工作:

    static void Main(string[] args)
    {
        IWindsorContainer container = new WindsorContainer();
        container.Kernel.Resolver.AddSubResolver(new ArrayResolver(container.Kernel));
        container.Install(Castle.Windsor.Installer.Configuration.FromAppConfig());

        var consumer = container.Resolve<Consumer>();
    }

但是,甚至只需配置即可,因为您不必设置实例:

  <configuration>
     <configSections>
        <section name="castle" type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler, Castle.Windsor" />
     </configSections>
     <castle>
        <components>
           <component id="Foo1" service="Test.IFoo, Test" type="Test.Foo1, Test" />
           <component id="Foo2" service="Test.IFoo, Test" type="Test.Foo2, Test" />
           <component id="Consumer" service="Test.Consumer, Test"/>
        </components>
     </castle>
  </configuration>

一如既往,事实证明温莎城堡很棒,但文档却不行,而且您会在网络上找到示例的许多不同版本不会使它变得更容易...
