Question What can replace public actions?

Hey everyone!

I have organized interaction between interfaces through public Action. But they periodically tell me that this is a bad practice, but they don’t tell me how to do it better. I understand that such an architecture may have a problem with the fact that this Action can call an extraneous class (although in my opinion it is obvious that this is not necessary).
Then I began to write such a construction, in the method and in the interface I indicated these methods.

Code (CSharp):

1.  
2. private Action restartGameAction;
3. public void RestartGameActionSubscribe(Action function) =>restartGameAction += function;
4. public void RestartGameActionUnsubscribe(Action function) => restartGameAction -= function;
5.  

It seems to me that such a construction is redundant, but I did not come up with another method for solving the problem and did not google it.
Please tell me what other methods are there to solve this problem?

 

If you want to prevent other classes from invoking a delegate (like an Action), you can use the

event

keyword:

public event Action RestartGameAction;

. This way the RestartGameAction Action can only be invoked from the class containing it.

 

Thank you so much! Exactly what I need.
