在Ninject 向构造参数中注入具有相同类型的参数

实际上这个有多种解决方法，加自定义Attribute，或Named()，但这些方式有一些侵入性，Named,要引用Ninject， 自定义Attribute，还要还要再写几行代码吗，所以使用下面的方法，

 

    public class All

    {

        private readonly II _a;

        private readonly II _b;

        public All( II a, II b)

        {

            _a = a;

            _b = b;

        }

        public void Print()

        {

            Console.WriteLine(_a.get());

            Console.WriteLine(_b.get());

        }

    }

    public interface II

    {

        string get();

    }

    class A : II

    {

        public string get()

        {

            return "a";

        }

    }

    class B : II

    {

        public string get()

        {

            return "b";

        }

    }
