C# Basics

Namespace: A Namespace is used to organize your code. It is collection of classes, interfaces, structs, enums and delegates

DataTypes: C# is a strongly-typed language. Before a value can be stored in a variable, the type of the variable must be specified .
The Built in datatypes in C#

• Boolean type
• Integral Type
• Floating Type
• Decimal Type
• String Type

Boolean Type: A variable of Boolean type will have values only True or False. The keyword bool is used in defining the datatype

eg: bool X = true;

The Variable X is of type bool and has the value true. If you try to assign any other value to the bool variable X then it will give a compile error

Integral Type: The integral datatypes are used to store  numbers. There are many Integral datatypes 

•  sbyte 
• byte
• short
• ushort
• int
• uint
• long
• ulong
• char

C# datatypes are categorized into two categories
