Integral types table (C# Reference)

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 CS1021 occurs.

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