C# EnumEnum in C# is also known as enumeration. It is used to store a set of named constants such as season, days, month, size etc. The enum constants are also known as enumerators. Enum in C# can be declared within or outside class and structs. Enum constants has default values which starts from 0 and incremented to one by one. But we can change the default value. Points to remember
C# Enum ExampleLet's see a simple example of C# enum.
using System;
public class EnumExample
{
public enum Season { WINTER, SPRING, SUMMER, FALL }
public static void Main()
{
int x = (int)Season.WINTER;
int y = (int)Season.SUMMER;
Console.WriteLine("WINTER = {0}", x);
Console.WriteLine("SUMMER = {0}", y);
}
}
Output: WINTER = 0 SUMMER = 2 C# enum example changing start index
using System;
public class EnumExample
{
public enum Season { WINTER=10, SPRING, SUMMER, FALL }
public static void Main()
{
int x = (int)Season.WINTER;
int y = (int)Season.SUMMER;
Console.WriteLine("WINTER = {0}", x);
Console.WriteLine("SUMMER = {0}", y);
}
}
Output: WINTER = 10 SUMMER = 12 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);
}
}
Output: Sun = 0 Mon = 1 Sat = 6 C# enum example: traversing all values using getNames()
using System;
public class EnumExample
{
public enum Days { Sun, Mon, Tue, Wed, Thu, Fri, Sat };
public static void Main()
{
foreach (string s in Enum.GetNames(typeof(Days)))
{
Console.WriteLine(s);
}
}
}
Output: Sun Mon Tue Wed Thu Fri Sat C# enum example: traversing all values using getValues()
using System;
public class EnumExample
{
public enum Days { Sun, Mon, Tue, Wed, Thu, Fri, Sat };
public static void Main()
{
foreach (Days d in Enum.GetValues(typeof(Days)))
{
Console.WriteLine(d);
}
}
}
Output: Sun Mon Tue Wed Thu Fri Sat
