Does this answer your question? [How to return value from Action()?](https://stackoverflow.com/questions/8099631/how-to-return-value-from-action) — gunr2171, Dec 07 '22 at 13:01
then use a `Func` instead of an `Action`. Action is for methods returning nothing, while Func is for methods returning a value. — MakePeaceGreatAgain, Dec 07 '22 at 13:01
`Action` is a delegate type for a method that takes parameter `T` and returns `void`. If you need a different signature, you need a different delegate type - rather than simply replacing `Action` with `Func` and calling it a day, I'd recommend reading up on, and toying with `delegate` types and understanding how they work, for they are a fundamental component of .net and C#. — Mathieu Guindon, Dec 07 '22 at 13:49
