在Simple注入器中注册Decorator，通用接口

Question

我对使用装饰器简单注入器的 IoC 有问题。

如何在 Ioc Simple 注入器中注册它？

var data = new Data();

var test = new Data2Decorator (data,

    new Data1Decorator(data, new XxxData(data)))

我这样尝试过。

_container.Register<Ixxx1>();

_container.Register<Ixxx2>();

_container.Register<Ixxx, Data>();

_container.Register<IData, XxxData>();

container.RegisterDecorator<IData, Data1Decorator>();

_container.RegisterDecorator<IData, Data2Decorator>():          

public interface Ixxx1

{

    public IEnumerable<...> x1 { get; set; }

}

public class Data1Decorator : DataDecorator

{

    public readonly Ixxx1 _xxx1; 

    public Data1Decorator(Ixxx1 xxx1, IData data) : base(data)

    {

        _xxx1 = xxx1;

    }

    public override Task Load()

    {

        return Task.WhenAll(new List<Task>() { ..., base.Load() })

        .ContinueWith((b) =>

        { 

               _xxx1.x1 = ...

        });

    }

}

常用存储数据

public interface Ixxx :

    Ixxx1,

    Ixxx2

{

}

public class Data: Ixxx

{ 

    public IEnumerable<...> x1 { get; set; }

    public IEnumerable<...> x2 { get; set; }

}
