The variables that are based on reference types store references to the actual data. The keywords that are used to declare reference types are:

Class - Refers to the primary building block for the programs, which is used to encapsulate variables and methods into a single unit.

Interface - Contains only the signatures of methods, properties, events, or indexers.

Delegate - Refers to a reference type that is used to encapsulate a named or anonymous method.
