C# - Data Types and Ranges

C# supports all the major data types and more. This page lists the most common types and the ranges of values they can hold.

All minimum and maximum values can be found using (data type).MinValue and (data type).MaxValue (e.g. int.MinValue).

Type  Size[Bytes]   Description                 Minimum      Maximum       Example 
bool    1         Named literal                  false        true  
sbyte   1         Signed byte                    -128         127  
byte    1         Unsigned byte                   0           255  
short   2         Signed short integer           -32768       32767  
ushort  2         Unsigned short                  0           65535  
int     4         Signed integer                 -2147483648  2147483647
