Get Enum Description value in C#

Enum : According to Microsoft Docs (Link), the enum keyword is used to declare an enumeration, a distinct type that consists of a set of named constants called the enumerator list.

Enum Description Value: This can be achieve by creating an extension method over the Enum data type.

using System;

using System.ComponentModel;

using System.Reflection;

namespace TestApp

{

    public enum Days

    {

        [Description("Monday")]

        MON,

        [Description("Tuesday")]

        TUE,

        [Description("Wednesday")]

        WED,

        [Description("Thursday")]

        THU,

        [Description("Friday")]

        FRI,

        [Description("Saturday")]

        SAT,

        [Description("Sunday")]

        SUN,

    }

    public static class EnumExtension

    {

        public static string GetDescriptionValue<T>(this T value)

        {

            if (value == null)

                throw new ArgumentNullException("value");

            string description = value.ToString();

            FieldInfo fieldInfo = value.GetType().GetField(description);

            DescriptionAttribute[] descAttributes = (DescriptionAttribute[])fieldInfo.GetCustomAttributes(

                                                    typeof(DescriptionAttribute), false);

            if (descAttributes != null && descAttributes.Length > 0)

                return descAttributes[0].Description;

            else

                return description;

        }

    }

    class Program

    {

        static void Main(string[] args)

        {

            Console.WriteLine(Days.MON.GetDescriptionValue<Days>());

            Console.WriteLine(Days.TUE.GetDescriptionValue<Days>());

            Console.WriteLine(Days.SUN.GetDescriptionValue<Days>());

            Console.ReadLine();

        }

    }
