四种注入方式

 public interface IPeople { void Live();}public interface IEat { void Eat();}public interface ISleep { void Sleep(); }public interface IPlay { void Play();}public class PlayBoy : IPeople{//构造函数注入public IEat PEat { get; set; }//属性注入
        [Dependency]public ISleep PSleep { get; set; }public IPlay PPlay { get; set; }public PlayBoy(IEat eat){ this.PEat = eat; }[InjectionMethod]public void Initialize(IPlay play){ this.PPlay = play; }public void Live(){this.PEat.Eat();this.PSleep.Sleep();this.PPlay.Play();Console.WriteLine("playboy is walking");}}public class BoyEat : IEat{public void Eat(){Console.WriteLine("eat rice and meat");}}public class BoySleep : ISleep{public void Sleep(){Console.WriteLine("sleep at 12:00 and wake up at 8:00");}}public class BoyPlay : IPlay{public void Play(){Console.WriteLine("play war3 and dota");}}

注册和解析

  IUnityContainer container = new UnityContainer();container.RegisterType<IPeople, PlayBoy>();container.RegisterType<IEat, BoyEat>();container.RegisterType<ISleep, BoySleep>();container.RegisterType<IPlay, BoyPlay>();var p = container.Resolve<IPeople>();p.Live();
