Enum in C#

Enum is Enumeration to store a set of named constants like year, product, month, season, etc.

The default value of Enum constants starts from 0 and increments. It has fixed set of constants and can be traversed easily.

Let us see an example.

We have set the enum like this −

public enum Vehicle { Car, Bus, Truck }

The following is the complete example.

Example

using System;
public class Demo {
   public enum Vehicle { Car, Bus, Truck }
   public static void Main() {
      int a = (int)Vehicle.Car;
      int b = (int)Vehicle.Bus;
      int c = (int)Vehicle.Truck;
      Console.WriteLine("Car = {0}", a);
      Console.WriteLine("Bus = {0}", b);
      Console.WriteLine("Truck = {0}", c);
   }
}

Output

Car = 0
Bus = 1
Truck = 2
