C# tutorial - Types

In this post we are going to see about types in c#.There are two kinds of types in C# value types and Reference types. Variables of value types directly contain the data.but in reference types in store the reference of the data.

C# value types are divided in to simple types, enum types, struct types, and nullable types.
C# reference types are divided in to class types, interface types, array types and delegate types.

Category		Description
Value types	Simple types	Signed integral: sbyte, short, int, long
		Unsigned integral: byte, ushort, uint, ulong
		Unicode characters: char
		IEEE floating point: float, double
		High-precision decimal: decimal
		Boolean: bool
	Enum types	User-defined types of the form enum Enu { }
	Struct types	User-defined types of the form struct Str {}
	Nullable types	Extensions of all other value types with a null value
Reference types	Class types	Ultimate base class of all other types: object
		Unicode strings: string
		User-defined types of the form class Copy {...}
	Interface types	User-defined types of the form interface Itest {...}
	Array types	Single- and multi-dimensional, for example, int[] and int[,]
	Delegate types	User-defined types of the form e.g. delegate int Del(...)

from this post you can learn the types present in c#.
