Csharp_Chap03

This document discusses constructors and destructors in C# classes. It explains that objects must be instantiated using the "new" keyword before their methods can be called. Static methods can be called directly on the class without creating an object instance. Instance variables are unique to each object, while static variables are shared among all objects of a class. The document uses several code examples to demonstrate how to properly create object instances and call both static and instance methods and variables.
