[Design Pattern] Strategy Pattern in c# 

Thanks for the clear explanation! Just out of curiosity, could we use Factory Method design pattern here to abstract that compression logic from the main class as well? I think we could have a factory that returns compression classes based on the given type (essentially we’d move switch to factory). Each compressors could use the same interface and that could allow factory to work with them and call their methods regardless of their implementation details. And this could be injected from outside just like how you do for strategy pattern. Would this approach be a viable alternative? Just trying to get a basic understanding of different patterns, sorry if this came across a little out of context.
