问题 I have one interface: IFoo Two classes implementing that interface: FooOne and FooTwo And two classes ClassOne and ClassTwo receiving an IFoo parameter in the constructor.

I can't do it at runtime so it must be in the config file. 回答1: Have a look at the Unity documentation. For a more readable config file you should define type aliases for IFoo , FooOne , FooTwo , ClassOne
