Question

如果这是一个愚蠢的问题，我会事先道歉：我对NInject很新。

我需要使用多个集合初始化我的应用程序，每个集合都有几个相同的对象。如果没有IoC，那将是：

  public ICollection<ICollection<IBusinessObject>> Piles = new ICollection<ICollection<IBusinessObject>>();

    public MyCollectionContainer()
    {
        Piles.Add(new List<IBusinessObject>({ new ObjectA(), new ObjectA()  });
        Piles.Add(new List<IBusinessObject>({ new ObjectB(), new ObjectB()  });
        Piles.Add(new List<IBusinessObject>({ new ObjectC(), new ObjectC()  });
    }

我想指示NInject为我做这项工作，以便拨打Kernel.Get<MyCollectionContainer>()可以完成与上述相同的工作，当然还有一些额外的灵活性。

换句话说，我想在绑定时指示NInject

Kernel.Bind<ICollection<ICollection<IBusinessObject>>>().To< /* A list of 3 */>();
Kernel.Bind<IList<IBusinessObject>>().To< /* A List of 2 IBusinessObject */>();
Kernel.Bind<IBusinessObject>().To< /* a different type depending on the container */>();

附带问题：我应该更好地使用Kernel.Get<MyCollectionContainer>()或Kernel.Get<ICollection<ICollection<IBusinessObject>>>()

编辑：在搜索解决方案时，我尝试在

模型中为我的馆藏定义自定义绑定

Kernel.Bind<IList<IBusinessObject>>()
        .ToConstructor(x => new List<IBusinessObject>(
            x.Inject<IList<IBusinessObject>>())
        );

使用扩展方法IConstructorArgumentSyntax.InjectMany(int i)：

Kernel.Bind<IList<IBusinessObject>>().To<ObjectA>();
Kernel.Bind<IList<IBusinessObject>>()
        .ToConstructor(x => new List<IBusinessObject>(
            x.InjectMany<IList<IBusinessObject>>(2))
        );

public static T InjectMany<T>(this IConstructorArgumentSyntax x, int numberOfInjections)
{
    /* loop */
    {
        x.Inject<T>();
    }
}

可悲的是，NInject拒绝调用x.Inject（）;抱怨说我已经潜入了他们的魔法：

System.InvalidOperationException : 
This method is for declaration that a parameter shall 
be injected only! Never call it directly.

使用NInject初始化多个集合
