In our sample enum file, we created TransactionStatus where it has enum values and ids. We also used the using System.ComponentModel.DataAnnotations so we can use the attribute [Display(Name = "")]

So let’s create our extension method.

        using System;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Reflection;
  
namespace ConsoleApp
{
  public static class EnumExtensions
  {
    public static string GetDisplayName(this Enum enumValue)
    {
      return enumValue.GetType()
        .GetMember(enumValue.ToString())
        .First()
        .GetCustomAttribute<DisplayAttribute>()
        ?.GetName();
    }
  }
}
      

Let’s try our extension method.

        var status = TransactionStatus.ForApproval;
status.GetDisplayName();
      

Then it will display For Approval.
