Question

我对IoC和Castle很新，我很难通过实现的界面注册课程。

在我的应用程序中，有几个程序集，每个程序集都有一个实现接口 IErrorCodes 的类。在运行时，确定是否存在一个（最多）这些程序集/类，并且总是存在 DefaultErrorCodes 类，当没有真正的实现时，应该使用该类。

以下代码导致实现（例如 UkErrorCodes ）存在于容器的 Services 部分中，但是当应用程序到达实现的部分时Castle会出错 IErrorCodes 应该被注入＆＃34;你忘了代理它＆＃34;

container.Register(
    Classes.FromAssemblyInDirectory(new AssemblyFilter("bin")).
                BasedOn<IErrorCodes>().
                Unless(t=> t.IsAbstract).
                WithServiceBase(),
    Component.For<IErrorCodes>()
               .IsFallback(c => c == typeof(DefaultErrorCodes)).LifestyleSingleton());
