The following list describe the C# built in types.


Integral numeric types

Type

Description / Range

bool

True or false

byte

0-255     Unsigned 8 bit integer

sbyte

-128 to 127       Signed 8 bit integer

short

-32,768 to 32,767         Signed 16-bit integer

ushort

0 to 65,535               Unsigned 16-bit integer

int

-2,147,483,648 to 2,147,483,647    Signed 32-bit integer

uint

0 to 4,294,967,295     Unsigned 32-bit integer

long

-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
Signed 64-bit integer

ulong

0 to 18,446,744,073,709,551,615
Unsigned 64-bit integer

Floating Types

float

±1.5 x 10−45 to ±3.4 x 1038             4 bytes

double

±5.0 × 10−324 to ±1.7 × 10308        8 bytes

decimal

±1.0 x 10-28 to ±7.9228 x 1028       16 bytes

Other Types

bool

 Represents true or false

char

Represents a Unicode UTF-16 character.

String 

Reference a sequence of zero or more Unicode UTF-16 characters.


We can use any of above types as variable types in our program code as per need.

Example : float  price=67855.78

                  double rate_item = 4535566.89999

                   int num=8900

                   char  letter = 'T'

                  string person ="Noah"
