How to work with variables in winforms?

Question

C++ / C#

Perhaps a stupid question, but still interesting how to write code correctly.

For an example, when working in winforms, you need to display at the end, count the values ​​of variables in one textbox. So that's where to properly initialize them, where to count them, and so on? I think it's not right to do it all in one button handler, for example?

Answer 1

If you can do everything in one button, then why not, why spray code across five files?

Answer 2

Try like this. The point is that there would be less logic in the form
