c# - Ninject v2+ injection dependent on parametername

Question

I know that with Ninject 1, it was possible to give specific instances depending on the parameter name.

E.g public SomeClass(ISomething left, ISomething right) {}

would resolve ISomething left to the default ISomething, but ISomething right to a different binding.

How can I do this with Ninject 2+?

Note: I do not want to use [Named("XZ")], because that would force me to make the main dll of my application a dependency of Ninject. Right now I have a separate DLL CompositionRoot that depends on Ninject, and nothing else: my main dll can be used without Ninject. I would like to keep it that way.

Edit: I updated the example to use left/right instead of simple/complex after the first answer. I do not want to hardcode this dependency in my inheritance structure.

Answer 1

我想到了：

Bind<ISomething >().To<LeftSomething>().When(a => a.Target.Name == "left");

Answer 2

为什么不创建派生接口ISimpleSomething和IComplexSomething？

这样，您可以为每个公开附加功能。

interface ISomething { ... }
interface IComplexSomething : ISomething { ... }
interface ISimpleSomething : ISomething { ... }
