Sounds like you are implementing a virtual method table.
Virtual method table - Wikipedia
So to do it in C# you would have e.g. a dictionary<string, action> and dispatch the call thusly: dict[param]()
To make it testable, DI friendly you would encapsulate this logic in a class / interface with e.g. registerhandler(string, action) and execute(string) methods etc.

How about using different classes to represent the different actions that the switch statement might have executed. I think that's what is known as "Replace Conditional With Polymorphism".
Replace Conditional with Polymorphism
Is that what you meant by Dependency Injection? Only problem I see is that it might lead to a lot of small classes. Maybe I could put them all in one file to save bloating out the solution?

For both of the above, the second parameter (myParam2) might be a method name or enum for some kind of state (e.g. "busy", "idle", "blocked").
