What Is Enum In C# ?
Enum or Enumerations is used to declare a list of named integer constants. The enum is used to give a name to each constant so that the constant integer can be referred using its name.
Enumerations appear in your source code. These are things that affect program logic because you’re going to have conditional statements based on the state of some entity comparing it with some enum value. This enums represents numerical values which can get used in place of IDs in database tables.
