What follows is a basic look at the C# programming language.
C# is a strongly typed language. That means that the variable type matters. You cannot assign a variable of one type to another of a different type without performing a type cast. C# is compiled into IL code that is then compiled just in time by the .NET framework. The .NET framework handles things like program execution and memory management. As a result C# is considered "managed code." C# is case sensitive so Var1 is different from var1.
Basic Syntax
White Space and Comments
C# uses the ; to terminate statements. As a result statements can have whitespace formatting characters(tabs, line feeds, carriage returns, etc.).
Example:
//This is a comment and will not execute CallSomeFunction(param1, param2, param3);
is the same as:
//This is a comment and will not execute CallSomefunction(param1, :param2, :param3);
Variable Declaration
//value types can be initialized upon instantiation
[scope] Type name = value;
//reference types can be initialized up instantiation
[scope] Type name = new Type(contructor params);
//or not
[scope] Type name = null;
Value Type Example:
private int myInt = 0;
Reference Type Example:
private string myNewString = "fred"; string myNewString = null;
Operators
Assignment Operator: = Equality Operator: == OR Operator: || AND Operator: && Addition: + Subtraction: - Multiplication: * Division: / Add to existing: += Subtract from existing: -=
