Unity容器，如何根据"calling"class注入特定的class

Question

我有以下片段

 public static void RegisterComponents(IUnityContainer container)
    {
        // register all your components with the container here
        // it is NOT necessary to register your controllers
        container.RegisterType<ISocialClient, ClientA>("a");
        container.RegisterType<ISocialClient, ClientB>("b");
        container.RegisterType<ISocialClient, ClientC>("c");

        GlobalConfiguration.Configuration.DependencyResolver = new UnityDependencyResolver(container);
    }

这是 WebApi2 项目。 所以我有 3 个控制器，

public class SocialAController : ApiController
{
    private ISocialClient client;
    ...
}

在 Unity 中有没有办法配置 SocialAController 获得 "ClientA" 实现，SocialBController 获得 "ClientB" 实现？

mspasiuk,

您可以通过以下方式注册例如 SocialAController 来做到这一点：

    container.RegisterType<SocialAController>(new InjectionConstructor(new ResolvedParameter<ISocialClient>("a")));
