Examples of c# code in form of a simple tutorial. Containing:
- Console Output
- Variables
- Declaration
- Arithmetic Operators
- Selection Statements
- Iteration Statements
- Arrays and Lists
- Parsing and Exceptions
- Functions
- Enum
- Classes
- Console Input
- File Read & Write
Local variables - nonCapitalLetter, camelCase.
Class, Function (Method - in a class) and Property name - CapitalLetter, PascalCase.
DO choose easy readable identifier (eg. HorizontalAlignment more English-readable than AlignmentHorizontal).
DO favor readability over brevity (property CanScrollHorizontally better than ScrollableX (obscure X-axis ref).
DO NOT use underscores (Hungarian notation), hyphens, or any other nonalphanumeric characters.
AVOID using identifiers that conflict with keywords of widely used programming languages.
DRY - Don't Repeat Yourself
YAGNI - You Aren't Gonna Need It (but have as much as you can out of the box)
KISS - Keep it Simple, Stupid - Kelly Johnson
"Good design is as little design as possible." - Dieter Rams
"Everything should be made as simple as possible, but not simpler." - Albert Einstein
"Complexity is your enemy. Any fool can make something complicated. It's hard to keep things simple."-Richard Branson
"Simple can be harder than complex: You have to work hard to get your thinking clean to make it simple." - Steve Jobs
"I have made this letter longer than usual, only because I have not had the time to make it shorter." - Blaise Pascal
"I have just three things to teach: simplicity, patience, compassion. These three are your greatest treasures." - Lao Tzu
LoD - Law of Demeter or principle of least knowledge
SoC - Separation of Concerns; Layers: presentation, business(service), DAL - data access layer, DB - database
DDD - Domain Driven Design
_ RP - Repository Pattern msdn/TheRepoPattern (allows dependency injection and unit test for EF)
_ DI - Dependecy Injection (IoC - Inversion of Control), loosely-coupled
PRG pattern - Post/Redirect/Get
GRASP - General Responsibility Assignment Software Patterns
OOP - Object Oriented Programming
SOLID (object-oriented design) SolidInPictures:
[S] SRP - Single Responsibility Principle (a class should have only a single responsibility)
[O] OCP - Open/Closed Principle (entities[class, function,..] to be open for extension, closed for modification)
[L] LSP - Liskov Substitution Principle (objects replaceable with subtypes instances without altering correctness)
[I] ISP - Interface Segregation Principle (many client-specific interfaces are better than one general-purpose interface)
[D] DIP - Dependency Inversion Principle (Depend upon abstractions, not upon concretions, Dependency injection)
