Answer 2

Enum is a set of constants. The problem is most people do not use enums in their code because they are not aware on when and where they can use it.

For example for a conditional flow rather than using int type variables you can use enums. This adds much readability in your code.

enum choice : int {Coke, RedBull, Boost}

if ( opt == choice.Coke)

{

}

else

{

}

 

Here rather using a string this is efficient because in the underlying architecture the enum uses int type indexes and this more readable than directly using integers.

 

Other than that you can specify values to enums and access them as well

Hi sateesh1234,

   Welcome to MSDN forums! what is the enum? Hope this will help you!  

 Enum is a costum data type(value type) in c# and the enum keyword is used to declare an enumeration, a distinct type consisting of a set of named constants called the enumerator list. Every enumeration type has an underlying type, which can be any integral type except char. The default underlying type of the enumeration elements is int. By default, the first enumerator has the value 0, and the value of each successive enumerator is increased by 1.

Hello Sateesh1234,

     Kindly find the below lines for your understanding on Enums.

     What is Enum and how to create it?

Enum(Enumerations) are related symbols that have fixed values. Use enumerations to provide a list of choices for developers using your class. For example, the following enumeration contains a set of titles:

' VB
Enum Titles As Integer
  Mr
  Ms
  Mrs
  Dr
End Enum

// C#
enum Titles : int { Mr, Ms, Mrs, Dr };

If you create an instance of the Titles type, Visual Studio displays a list of the available values when you assign a value to the variable. Although the value of the variable is an integer, it is easy to output the name of the symbol rather than its value, as shown here:

' VB
Dim t As Titles = Titles.Dr
Console.WriteLine("{0}.", t) ' Displays "Dr."

// C#
Titles t = Titles.Dr;
Console.WriteLine("{0}.", t); // Displays "Dr."

The purpose of enumerations is to simplify coding and improve code readability by enabling you to use meaningful symbols instead of simple numeric values. Use enumerations when developers consuming your types must choose from a limited set of choices for a value.

Kindly, let me know if you need further understanding.
