温莎城堡流畅​​API：定义明确的依赖 [英] Castle Windsor Fluent API: Define dependency explicitly

问题描述

由于以下配置。

        Container.Register(Component.For<A>().Named("foo"));
        Container.Register(Component.For<B>().Named("foobar"));

        Container.Register(
            AllTypes.Pick()
            .FromAssemblyNamed("MyAssembly")
            .If(t => t.Name.EndsWith("ABC"))
            .Configure(c => c.LifeStyle.Is(LifestyleType.Transient))
            .WithService.Select(i => typeof(I))
        );

        Container.Register(
            AllTypes.Pick()
            .FromAssemblyNamed("MyAssembly")
            .If(t => t.Name.EndsWith("123"))
            .Configure(c => c.LifeStyle.Is(LifestyleType.Transient))
            .WithService.Select(i => typeof(I))
        );

如果我知道，界面中的我暴露属性P，那类A和B可以被分配为P;我如何明确规定从AllTypes呼叫类型的第一集合应具有属性P设置为与foo的ID的类型，而第二个集合应具有相同的属性设置为类型与foobar的的id

If I know that the interface "I" exposes a property "P", and that the classes A and B can be assigned to P; how do I explicitly state that the first collection of types from the AllTypes call should have the property P set to the type with id of "foo", and the second collection should have the same property set to the type with the id of "foobar"?

使用XML配置，这可以通过显式设置使用$ {ID}符号的参数来完成。我认为它的流畅API类似。

Using XML config this can be done by explicitly setting the parameters using the ${id} notation. I assume its similar in the fluent API.

感谢。

推荐答案

您在正确的轨道上 - 你需要做的是配置每个组件的参数是什么，提供名为P，其值为$ {参数富}或$ {} FOOBAR根据您的情况，这里有一个工作的xUnit事实（向下滚动向底部的实际注册code）这说明您的情况。

You are on the right track - what you need to do is configure the parameters of each component, supplying the parameter named "P" with the value "${foo}" or "${foobar}" depending on your scenario, here's a working xunit fact (scroll down towards the bottom for the actual registration code) which demonstrates your scenario.

namespace Question651392
{
  public class First123 : I
  {
    public AbstractLetter P { get; set; }
  }

  public class Second123 : I
  {
    public AbstractLetter P { get; set; }
  }

  public class FirstABC : I
  {
    public AbstractLetter P { get; set; }
  }

  public class SecondABC : I
  {
    public AbstractLetter P { get; set; }
  }

  public interface I
  {
    AbstractLetter P { get; set; }
  }

  public abstract class AbstractLetter
  {
  }

  public class B : AbstractLetter
  {
  }

  public class A : AbstractLetter
  {
  }

  public class RegistrationFacts
  {
    [Fact]
    public void EnsureParametersCanBeSetWhenRegisteringComponentsInBulk()
    {
      WindsorContainer Container = new WindsorContainer();

      Container.Register(Component.For<A>().Named("foo"));
      Container.Register(Component.For<B>().Named("foobar"));

      Container.Register(
          AllTypes.Pick()
          .FromAssembly(GetType().Assembly)
          .If(t => t.Name.EndsWith("ABC"))
          .Configure(c => c.LifeStyle.Is(LifestyleType.Transient))
          .Configure(c=>c.Parameters(Parameter.ForKey("P").Eq("${foo}")))
          .WithService.Select(new[] { typeof(I) })          
      );

      Container.Register(
          AllTypes.Pick()
          .FromAssembly(GetType().Assembly)
          .If(t => t.Name.EndsWith("123"))
          .Configure(c => c.LifeStyle.Is(LifestyleType.Transient))
          .Configure(c => c.Parameters(Parameter.ForKey("P").Eq("${foobar}")))
          .WithService.Select(new[] { typeof(I)})
      );

      var all = Container.ResolveAll<I>();

      var firstABC = all.Single(i => i is FirstABC);
      Assert.IsType(typeof(A), firstABC.P);

      var first123 = all.Single(i => i is First123);
      Assert.IsType(typeof (B), first123.P);

      Assert.Equal(4, all.Count());
    }
  }
}
