如果我有接口和实现类
public interface IA {}
public class X : IA {}
public class Y : IA {}
然后这个注册很好
var w = new WindsorContainer();
w.Register(Component.For<IA>().ImplementedBy<X>());
w.Register(Component.For<IA>().ImplementedBy<Y>());
与
相同var w = new WindsorContainer();
w.Register(Component.For<IA>().Instance(new X()));
w.Register(Component.For<IA>().Instance(new Y()));
但是如果我尝试将具体类注册为
var w = new WindsorContainer();
var x1 = new X();
var x2 = new X();
w.Register(Component.For<X>().Instance(x1));
w.Register(Component.For<X>().Instance(x2));
它抛出异常:Castle.MicroKernel.ComponentRegistrationException : Component X could not be registered. There is already a component with that name. Did you want to modify the existing component instead? If not, make sure you specify a unique name.
如果是意图限制 - 为什么?有没有办法在不添加并不总是必要的界面的情况下实现集合解析?
答案 0 :(得分:1)
您是否要修改现有组件?如果没有,请制作 确定你指定了一个唯一的名称。
Component.For<X>().Instance(x1).Named("x1")
