Different Data Types and their range in C#.Net
There are different data types in C#.Net. Each data type has its own range of values. Below you can find C# data types, their corresponding IL(Intermediate Language) types and its range of values.
| C# Type | IL Type | Range |
|---|---|---|
| byte | System.Byte | 0 to 255 |
| short | System.Int16 | -32768 to 32767 |
| int | System.Int32 | -2^31 to 2^31-1 |
| long | System.Int64 | -2^63 to 2^63-1 |
| sbyte | System.Sbyte | -128 to 127 |
| ushort | System.UInt16 | 0 to 65535 |
| uint | System.UInt32 | 0 to 2^32-1 |
| ulong | System.UInt64 | 0 to 2^64-1 |
| float | System.Single | 4 bytes |
| double | System.Double | 8 bytes |
| decimal | System.Decimal | 16 bytes |
| bool | System.Boolean | true or false |
| char | System.Char | 2 bytes |
| string | System.String | |
| object | System.Object |
As shown above byte, ushort and ulong data types can store only unsigned values(only positive values) whereas short, int, long and sbyte types can store both signed and unsigned values(both positive and negative) within their range.
The size of the char data type has been increased to 2 bytes in C# 4.0 to provide support for Unicode characters(characters other than English), which are also represented with numeric values known as Unicode value like ASCII values for English characters. Unicode characters required 2 bytes of memory for storage. String data type length varies depends on the number of characters it stores.
Object is the parent of all the data types which can store any type of value whether it is int, string, char....etc and this is also has variable length depending on its value.
