Communicate between two windows forms in C#

Question

I have two forms, one is the main form and the other is an options form. So say for example that the user clicks on my menu on the main form: Tools -> Options

Answer 1

MVC, MVP, MVVM -- slight overkill for someone admittedly saying they want tutorials. Those are theories that have entire courses dedicated to them.

As already posted, passing an object around is probably easiest. If treating a class as an object (interchangeable in this sense) is new, then you may want to spend another 2-4 weeks figuring out properties and constructors and such.

I'm not a C# master by any means, but these concepts need to be pretty concrete if you want to go much further beyond passing values between two forms (also classes/objects in their own right). Not trying to be mean here at all, it just sounds like you're moving from something like VB6 (or any language with globals) to something far more structured.

Eventually, it will click.
