C# Integral Types of Data Types

Learn about the Integral Types of Data Types in C# with their system types, occupied size, value range and value types. By IncludeHelp Last updated : April 04, 2023

C# Integral Types

The integral neumic types of data types are used to store the integer numbers and all these data types support the various arithmetic, logical, bitwise, and equality operations.

List of Integral Types of Data Types

The list of the built-in integral neumic types C# is:

Type	System type	Size	Value range	Value type
sbyte	System.SByte	8-bits	-128 to 127	Signed integer
byte	System.Byte	8-bits	0 to 255	Unsigned integer
char	System.Char	16-bits	U+0000 to U+ffff	Unicode character
short	System.Int16	16-bits	-32,768 to 32,767	Signed integer
ushort	System.Int16	16-bits	0 to 65,535	Unsigned integer
int	System.Int32	32-bits	-2,147,483,648 to 2,147,483,647	Signed integer
uint	System.Int32	32-bits	0 to 4,294,967,295	Unsigned integer
long	System.Int64	64-bits	-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807	Signed integer
ulong	System.Int64	64-bits	0 to 18,446,744,073,709,551,615	Unsigned integer

C# Example of Integral Types of Data Types

In this example, we are declaring variables of different integral types of data types, initializing with the different value, printing the system types of the variables, size of the types and min, max values of the types.

using System;
using System.Text;

namespace Test {
  class Program {
    static void Main(string[] args) {
      //sbyte
      sbyte a = -10;
      Console.WriteLine("sbyte...");
      Console.WriteLine("a = " + a);
      Console.WriteLine("type of variable = " + a.GetType());
      Console.WriteLine("size of sbyte = " + sizeof(sbyte));
      Console.WriteLine("Min value of sbyte = " + sbyte.MinValue);
      Console.WriteLine("Max value of sbyte = " + sbyte.MaxValue);
      Console.WriteLine();

      //byte
      byte b = 10;
      Console.WriteLine("byte...");
      Console.WriteLine("b = " + b);
      Console.WriteLine("type of variable = " + b.GetType());
      Console.WriteLine("size of byte = " + sizeof(byte));
      Console.WriteLine("Min value of byte = " + byte.MinValue);
      Console.WriteLine("Max value of byte = " + byte.MaxValue);
      Console.WriteLine();

      //char
      char c = 'P';
      Console.WriteLine("char...");
      Console.WriteLine("c = " + c);
      Console.WriteLine("type of variable = " + c.GetType());
      Console.WriteLine("size of char = " + sizeof(char));
      Console.WriteLine("Min value of char = " + (int)(char.MinValue));
      Console.WriteLine("Max value of char = " + (int)(char.MaxValue));
      Console.WriteLine();

      //short
      short d = -18910;
      Console.WriteLine("short...");

      Console.WriteLine("size of short = " + sizeof(short));
      Console.WriteLine("Min value of short = " + short.MinValue);
      Console.WriteLine("Max value of short = " + short.MaxValue);
      Console.WriteLine();

      //ushort
      ushort e = 18910;
      Console.WriteLine("ushort...");
      Console.WriteLine("e = " + e);

      Console.WriteLine();

      //int
      int f = -893818910;
      Console.WriteLine("int...");
      Console.WriteLine("f = " + f);
      Console.WriteLine("type of variable = " + f.GetType());
      Console.WriteLine("size of int = " + sizeof(int));
      Console.WriteLine("Min value of int = " + int.MinValue);
      Console.WriteLine("Max value of int = " + int.MaxValue);
      Console.WriteLine();

      //uint
      int g = 893818910;
      Console.WriteLine("uint...");
      Console.WriteLine("g = " + g);
      Console.WriteLine("type of variable = " + g.GetType());
      Console.WriteLine("size of uint = " + sizeof(uint));
      Console.WriteLine("Min value of uint = " + uint.MinValue);
      Console.WriteLine("Max value of uint = " + uint.MaxValue);
      Console.WriteLine();

      //long
      long h = -90909893818910;
      Console.WriteLine("long...");
      Console.WriteLine("h = " + h);
      Console.WriteLine("type of variable = " + h.GetType());
      Console.WriteLine("size of long = " + sizeof(long));
      Console.WriteLine("Min value of long = " + long.MinValue);
      Console.WriteLine("Max value of long = " + long.MaxValue);
      Console.WriteLine();

      //ulong
      ulong i = 90909893818910;
      Console.WriteLine("ulong...");
      Console.WriteLine("i = " + i);
      Console.WriteLine("type of variable = " + i.GetType());
      Console.WriteLine("size of ulong = " + sizeof(ulong));
      Console.WriteLine("Min value of ulong = " + ulong.MinValue);
      Console.WriteLine("Max value of ulong = " + ulong.MaxValue);
      Console.WriteLine();

      //hit ENTER to exit
      Console.ReadLine();
