The Primitive Types Available in C#

The list of primitive types available in C# is very similar to C and C++. One of the major reasons for the cross-language interoperability of the .NET Framework is that all languages share a common type system: the CTS. The primitive types in C# are just aliases for CTS types. Table 4-4 shows the primitive types available in C#.

Table 4-4. A Mapping of C# types to CTS types

C# Types	CLS Compliant	Equivalent CTS Type	Description
bool	Yes	System.Boolean	True or false
byte	Yes	System.SByte	Unsigned 8-bit number
sbyte	No	System.Byte	Signed 8-bit number
char	Yes	System.Char	16-bit Unicode character
int	Yes	System.Int32	Signed 32-bit number
uint	No	System.UInt32	Unsigned 32-bit number
long	Yes	System.Int64	Signed 64-bit number
ulong	No	System.UInt64 ...
