C＃泛型包含泛型？ Ť <TValue>

Question

I got lost implementing a interface where I need TKey , TValue and TMessageListener

public interface IHelper<TKey, TValue, TMessageListener>

but my TMessageListener is TMessageListener<TValue> how can I declare this at the interface layer?

Answer 1

可以通过以下类型约束来实现。

public interface IHelper<TKey,TValue,TMsgLst> where TMsgLst : TMessageListener<TValue>
