Answer 1

Here's what you can do here. You can create an interface [ICommand] where you can place a common function [eg: Execute].

Then you just needs to initiate that member with appropriate type and call the Execute function. This might include more functions in the future and is thus extended.

Also, you can create a factory method where you can pass the parameter and get the appropriate class to work with.

Hope that helps.
