Integral types table

Domains: C#

The following table shows the sizes and ranges of the integral types, which constitute a subset of simple types.

Type Range Size
sbyte                                         -128 to 127           Signed 8-bit integer
byte                                            0 to 255           Unsigned 8-bit integer
char                                     U+0000 to U+ffff           Unicode 16-bit character
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

Remarks

If the value represented by an integer literal exceeds UInt64.MaxValue, a compiler error CS1021occurs.

Use the System.Numerics.BigInteger class to represent an arbitrarily large signed integer.
