The structure below shows the various basic types of C# and the types they map to in the .Net framework.
| C# Short Name | .Net Class | Declaration | Description |
| bool | Boolean | bool isValid = true; |
8 bit true or false |
| sbyte | SByte | sbyte b = -1 | signed 8 bit integer |
| byte | Byte | byte b = 1; | 8 bit unsigned integer |
| char | Char | char = 'a' | 16 bit single Unicode character |
| short | Int16 | short s = 123; | 16bit signed integer |
| ushort | UInt16 | ushort s = 15; | 16bit unsigned integer |
| int | Int32 | int i = -1000000; | 32bit signed integer |
| uint | UInt32 | uint i = 50000; | 32bit unsigned integer |
| long | Int64 | long = 2000; | 64 bit signed integer |
| ulong | UInt64 | ulong = 2000; | 64 bit unsigned integer |
| float | Single | float f = 1.04f; | 4 byte single precision floating point |
| double | Double | double d = 1.0E-13 | 8 byte double precision floating point |
| decimal | Decimal | 16 byte precise fractional or integral type that can represent decimal numbers with 29 significant digits | |
| string | String | string s = "abcd"; | A sequence of unicode characters |
Binary Values
You can't specify a binary value in C# – specify in hexadecimal instead.
