）注册了所有类，几乎所有DI容器需要做的就是允许您使用GetService()查找对象的实例。...比较GetService （）和GetRequiredService （） 鉴于我们不再使用.NET 1.0，如果你想从IServiceProvider中检索服务，你可能使用了通用的泛型GetService...()扩展方法，而不是GetService(Type)接口方法。...首先，从GetService()方法的文档开始： GetService()返回一个serviceType类型的服务对象。如果返回的是一个没有类型的服务对象serviceType则返回null。...这可能是使用GetService()唯一有效的理由。如果您的代码只有在注册了给定服务时才能运行，那么您可能需要使用GetService()。

举个简单的例子，我们创建一个名为Cat的DI容器类，那么我们可以通过调用具有如下定义的扩展方法GetService从某个Cat对象获取指定类型的服务对象。...1: cat.GetService(): Foo 2: cat.GetService().Bar: Bar 3: cat.GetService().Baz...: Baz 4: cat.GetService().Baz.Qux: Qux 在对Cat容器的用法有了基本了解之后，我们来正式讨论它的总体设计和具体实现。...针对服务类型（服务接口类型或者具体服务类型均可）的服务对象提供机制实现在GetService方法中。...执行构造函数传入的参数是递归地调用GetService方法根据参数类型获得的。
AppDependencyResolver.Current.GetService() : (ILoginBusiness)AppDependencyResolver.Current.GetService...new的方法去实例化，就需要把构造方法中的参数在工厂的构造方法里也加入进去，所以这里用了一个AppDependencyResolver,这里的AppDependencyResolver.Current.GetService...= serviceProvider; } private readonly IServiceProvider _serviceProvider; public object GetService...(Type serviceType) { return _serviceProvider.GetService(serviceType); } public T...GetService() { return _serviceProvider.GetService(); } } 关于工厂的单元测 关于工厂，我们只需要测返回的对象是否是我们需要的就可以了
