    {  
        int x = (int)Season.WINTER;  
        int y = (int)Season.SUMMER;

C# enum example for Days

using System;  

public class EnumExample  
{  
    public enum Days { Sun, Mon, Tue, Wed, Thu, Fri, Sat };  
  
    public static void Main()  
    {  
        int x = (int)Days.Sun;  

        int y = (int)Days.Mon; 
 
        int z = (int)Days.Sat;

        Console.WriteLine("Sun = {0}", x);
  
        Console.WriteLine("Mon = {0}", y);
  
        Console.WriteLine("Sat = {0}", z);  
    }
