Appendix A - Principles of Object-Oriented Programming
bySimon Robinsonet al.
Wrox Press 2002

  

The aim of this appendix has been to introduce you to the basic concepts of object-oriented (OO) design in C#:

• classes, objects, and instances

• fields, methods , and properties

• overloading

• inheritance and class hierarchies

• polymorphism

• interfaces

OO programming methodology is strongly reflected in the design of the C# language, and of Intermediate Language too - we will see this as we begin to use the .NET base classes. Microsoft has done this because with our current understanding of programming techniques, it simply is the most appropriate way of coding up any large library or application.
