C# Enums
An enum is a special “class” that represents a group of constants (unchangeable/read-only variables).
To create an enum, use the enum keyword (instead of class or interface), and separate the enum items with a comma:
Example
enum Level
{
Low,
Medium,
High
}
You can access enum items with the dot syntax:
Level myVar = Level.Medium; Console.WriteLine(myVar);
Enum is short for “enumerations”, which means “specifically listed”.
