IOC容器-Autofac

//创建一个容器建造者
ContainerBuilder containerBuilder = new ContainerBuilder();
//注册普通类
containerBuilder.RegisterType<Honer>();
//build一下，得到一个容器
IContainer container = containerBuilder.Build();
//可以基于容器来获取对象的实例
Honer phone = container.Resolve<Honer>();

ContainerBuilder containerBuilder = new ContainerBuilder();
//将Honer类注册为IPhone接口的实现
containerBuilder.RegisterType<Honer>().As<IPhone>();
IContainer container = containerBuilder.Build();
IPhone phone = container.Resolve<IPhone>();
