这里解释如何在代码中执行此操作: Unity Register two interfaces as one singleton
_container.RegisterType<EventService>(new ContainerControlledLifetimeManager());
_container.RegisterType<IEventService, EventService>();
_container.RegisterType<IEventServiceInformation, EventService>();
bool singleton = ReferenceEquals(_container.Resolve<IEventService>(), _container.Resolve<IEventServiceInformation>());
如何在XML配置中执行此操作?

我个人喜欢在别名中拼出名称空间和程序集。所以xml:
<unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
<alias alias="Event_Interface" type="Mynamespace.IEventService, MyAssembly"/>
<alias alias="EventService_Interface" type="Mynamespace.IEventServiceInformation, MyAssembly"/>
<alias alias="Event_Class" type="Mynamespace.EventService, MyAssembly"/>
<container>
<register type="Event_Interface" mapTo="Event_Class">
<lifetime type="singleton"/>
</register>
<register type="EventService_Interface" mapTo="Event_Class">
<lifetime type="singleton"/>
</register>
</container>
</unity>
代码:
IUnityContainer container = new UnityContainer().LoadConfiguration();

我还没有使用配置文件进行统一,但根据文档说明它是
<unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
<namespace name="MyApp.Implementations" />
<assembly name="MyApp" />
<container>
<register type="IEventService" mapTo="EventService" />
<register type="IEventServiceInformation" mapTo="EventService" />
</container>
</unity>
