Reference section
The final section of this article is a reference of as many objects, members, and modifiers I can think of, showing both their C# and VB equivalents.
OBJECTS
| Name | Definition |
|---|---|
| Project | part of current open Solution |
| Assembly | compiled API package containing usable objects |
| Namespace | group of classes and other objects |
| class | encapsulation of data and behavior |
| interface | skeleton class containing signatures only |
| structure | like a class, but does not support inheritance |
| enum | assigns names to a group of constant values |
| delegate | pointer to a method; used for event handling |
MEMBERS
* = no applicable keyword in C#; the presense of parens ( ) distiguishes a method.
| C# | VB | definition |
|---|---|---|
| ( ) * | function( ) / sub( ) | method |
| * | property / dim | property or variable |
| event | event | condition that invokes a specified method |
| const | const | constant |
MODIFIERS
| C# | VB | definition |
|---|---|---|
| public | public | can be invoked externally |
| private/internal/protected | private/friend/protected | canNOT be invoked externally |
| void | sub | method does NOT return a value |
| type | function...as | method DOES return a value |
| static | shared | class instantiation not required |
| [get] | readonly | property is read-only |
| abstract | MustInherit/MustOverride | must be inherited / over-written |
| sealed | NotInheritable/NotOverridable | canNOT be inherited / over-written |

Conclusion
This article has just been an basic introduction to writing programs in .Net using the .Net framework and/or classes or objects written by others. Obviously, there is much more to OOP. This article barely touched on topics such as inheritance, polymorphism, interfaces, delegates, events, enumerators, and more. Then of course, there's the entire subject of writing classes!
OOP is a big topic that brings power to programmers that previous generations could only dream of. The downside is that OOP takes a long time to master. But hopefully, the information contained herein has broken down some barriers and helped it all to make a little more sense.
