Question

I\'ve got a property in my model called \"Promotion\" that its type is a flag enum called \"UserPromotion\". Members of my enum have display attributes set as follows:

For ASP.Net Core 3.0, this worked for me (credit to previous answerers).

My Enum class:

using System;
using System.Linq;
using System.ComponentModel.DataAnnotations;
using System.Reflection;

public class Enums
{
    public enum Duration
    { 
        [Display(Name = "1 Hour")]
        OneHour,
        [Display(Name = "1 Day")]
        OneDay
    }

    // Helper method to display the name of the enum values.
    public static string GetDisplayName(Enum value)
    {
        return value.GetType()?
       .GetMember(value.ToString())?.First()?
       .GetCustomAttribute()?
       .Name;
    }
}

My View Model Class:

public class MyViewModel
{
    public Duration Duration { get; set; }
}

An example of a razor view displaying a label and a drop-down list. Notice the drop-down list does not require a helper method:

@model IEnumerable 

@foreach (var item in Model)
{
    @Enums.GetDisplayName(item.Duration)
    

        Select Duration
        
        
    
}
