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();
