Data Types

An important part in the life of a C# programmer is the management of data types. Just as in C and C++, every variable has a fixed data type. Every data type provides a rich set of operators that can be used to perform a very special operation. Objects can be seen as data types as well, but we'll take a closer look at that later in this book.

Predefined Data Types

C# supports a list of predefined data types. In this section, we examine the most important types. Table 3.1 contains an overview.

Table 3.1. Predefined Data Types

C#	MONO	SIGNED	MEMORY	RANGE
sbyte	System.Sbyte	Yes	1 byte	–128 to 127
short	System.Int16	Yes	2 bytes	–32768 to 32767
int	System.Int32	Yes	4 bytes	–2147483648 to 2147483647
