.NET for Java Developers: Migrating to C#

7.4. The Built-in Value Types

As mentioned earlier, all C# types inherit from the System.Object class, and therefore most of the built-in types that we will discuss have a representation in the System namespace. For example, int is a keyword that is used to represent an integer value type, and it is also represented by the System.Int32 class. The simple built-in types can be further classified as integral types, floating-point types, decimal types, and Boolean types.

Table 7.2. Built-in Integral Types (C#)

Type (Keyword)	Size	.NET Framework Type
sbyte	Signed 8-bit integer	System.Sbyte
byte	Unsigned 8-bit integer	System.Byte
char	Unicode 16-bit character	System.Char
short	Signed 16-bit integer	System.Int16
ushort	Unsigned 16-bit integer	System.Uint16
int	Signed 32-bit ...
