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.
