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.
