An enumeration is a set of named integer constants. The keyword enum declares an enumerated type. The general form for an enumeration is enum name { enumeration list };
Here, the type name of the enumeration is specified by name. The enumeration list is a comma-separated list of identifiers.

Here is an example. It defines an enumeration called Apple that enumerates various types of apples:

enum Apple { Jonathan, GoldenDel, RedDel, Winesap,
Cortland, McIntosh };

A key point to understand about an enumeration is that each of the symbols stands for an integer value.

Enumeration is named integral constants. You can store only the value types in the enum, In c# we have only two types of value types there are enum and struct because it can store the equivalent value in a stack, not in heap.
