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;
