Function available in whole project C#

Question

I have a C# project with many winforms in it. I would like to have a function available to all of these forms. The solution I have right now is a separate class with this function, and then in the forms like this:

Exit quitter = new Exit();
            quitter.exitProgram(sender, e);

Is there a better way for my fnction to be available inside every form without having to initialize a class with this function every time?

Answer 1

You can write a helper class, which will contain all common functionalities shared by all winforms and write static method to avoid object instantiation.

Something like,

public class WinformHelper
{
    public static ExitProgram(object sender, System.EventArgs e)
    {
     //Your business logic
    }
}

Use in winforms,

WinformHelper.ExitProgram(sender, e);
