A Beginner's Guide to C-Sharp-Ch09: Variable Scope, Local vs Global Variables; How to pass between Forms (ABGC)

Chapter 9 (45 pages) is a short, but important chapter that discusses how variables have a "scope" – a time-to-live. Understanding this helps write tight and efficient code, and helps keep the program's size from exploding in Task Manager.

Important concepts on how to pass variables to other forms within the same program are described and demonstrated.
Topics: Local and Private variables. Scope within loops, form-level (class-level) variables, Form Load events, "Global" variables, passing variables to other forms. Using Get-Set variables. Calling Variables "By Ref"
