Data Types c# code example

Example 1: c# data types

Type	|	Represents 							|	Range							|	Default Value
bool		Boolean value							True or False						False
byte		8-bit unsigned integer					0 to 255							0
char		16-bit Unicode character				U +0000 to U +ffff					'\0'
decimal		128-bit precise decimal values 			(-7.9 x 1028 to 7.9 x 1028) 		0.0M
			with 28-29 significant digits			/ 100 to 28
double		64-bit double-precision floating 		(+/-)5.0 x 10-324 					0.0D
			point type								to (+/-)1.7 x 10308
float		32-bit single-precision floating 		-3.4 x 1038 to + 3.4 x 1038			0.0F
  			point type
int			32-bit signed integer type				-2,147,483,648 to 2,147,483,647		0
long		64-bit signed integer type				-9,223,372,036,854,775,808 			0L
  													to 9,223,372,036,854,775,807
sbyte		8-bit signed integer type				-128 to 127							0
short		16-bit signed integer type				-32,768 to 32,767					0
uint		32-bit unsigned integer type			0 to 4,294,967,295					0
ulong		64-bit unsigned integer type			0 to 18,446,744,073,709,551,615		0
ushort		16-bit unsigned integer type			0 to 65,535							0

Example 2: c# data types

// -------DATA TYPES ------- //

sbyte myNum = 1;             // Smallest range of integer numbers
uint myNum = 3;				 // Only positive integer numbers
short myNum = 4;             // Short range of integer numbers
int myNum = 5;               // Integer (whole numbers)
long myNum = 10;             // Biggest range of integer numbers 
float myFloat = 1.2f;        // Smallest range of floating point numbers
double myDoubleNum = 5.99;   // Big range of floating point numbers
decimal myDecimalNum = 2.2M; // Biggest precision in floating point numbers
char myLetter = 'D';         // Character
string myString = "Hello!"   // Strings
bool myBool = true;          // Boo

Example 3: c# int

int MyInt = 1;

Example 4: c# data types

// -------DATA TYPES ------- //

sbyte myNum = 1;             // Smallest range of integer numbers
uint myNum = 3;				 // Only positive integer numbers
short myNum = 4;             // Short range of integer numbers
int myNum = 5;               // Integer (whole numbers)
long myNum = 10;             // Biggest range of integer numbers 
float myFloat = 1.2f;        // Smallest range of floating point numbers
double myDoubleNum = 5.99;   // Big range of floating point numbers
decimal myDecimalNum = 2.2M; // Biggest precision in floating point numbers
char myLetter = 'D';         // Character
string myString = "Hello!"   // Strings
bool myBool = true;          // Boolean

Example 5: C# Data Type

short s1 = -32768;
short s2 = 32767;
short s3 = 35000;//Compile-time error: Constant value '35000' cannot be converted to a 'short'

ushort us1 = 65535;
ushort us2 = -32000; //Compile-time error: Constant value '-32000' cannot be converted to a 'ushort'

Console.WriteLine(Int16.MaxValue);//32767
Console.WriteLine(Int16.MinValue);//-32768
Console.WriteLine(UInt16.MaxValue);//65535
Console.WriteLine(UInt16.MinValue);//0

Example 6: c# data types

using System;
class BoxingExample
{
    static void Main()
    {
        int i = 123;
        object o = i;    // Boxing
        int j = (int)o;  // Unboxing
    }
}
