Building further on Aydin's and Todd's answers, here is an extension method that also lets you get the name from a resource file

<pre><code>using AppResources;
using System;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Reflection;
using System.Resources;

public static class EnumExtensions
{
 public static string GetDisplayName(this Enum enumValue)
 {
 var enumMember= enumValue.GetType()
 .GetMember(enumValue.ToString());

 DisplayAttribute displayAttrib = null;
 if (enumMember.Any()) {
 displayAttrib = enumMember 
 .First()
 .GetCustomAttribute&lt;DisplayAttribute&gt;();
 }

 string name = null;
 Type resource = null;

 if (displayAttrib != null)
 {
 name = displayAttrib.Name;
 resource = displayAttrib.ResourceType;
 }

 return String.IsNullOrEmpty(name) ? enumValue.ToString()
 : resource == null ? name
 : new ResourceManager(resource).GetString(name);
 }
}
</code></pre>

and use it like

<pre><code>public enum Season 
{
 [Display(ResourceType = typeof(Resource), Name = Season_Summer")]
 Summer
}
</code></pre>

blocks|key|448665|text|如果你使用的是MVC5.1或更高版本，有一种更简单、更清晰的方法:只需使用数据注释(来自System.ComponentModel.DataAnnotations命名空间)，如下所示：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|448666|public+enum+Color

If you are using MVC 5.1 or upper there is simplier and clearer way: just use data annotation (from <code>System.ComponentModel.DataAnnotations</code> namespace) like below:

<pre><code>public enum Color
{
 [Display(Name = "Dark red")]
 DarkRed,
 [Display(Name = "Very dark red")]
 VeryDarkRed,
 [Display(Name = "Red or just black?")]
 ReallyDarkRed
}
</code></pre>

And in view, just put it into proper html helper:

<pre><code>@Html.EnumDropDownListFor(model =&gt; model.Color)
</code></pre>

I tried doing this as an edit but it was rejected; I can't see why.

The above will throw an exception if you call it with an Enum that has a mix of custom attributes and plain items, e.g.

<pre><code>public enum CommentType
{
 All = 1,
 Rent = 2,
 Insurance = 3,
 [Display(Name="Service Charge")]
 ServiceCharge = 4
}
</code></pre>

So I've modified the code ever so slightly to check for custom attributes before trying to access them, and use the name if none are found.

<pre><code>using System;
using System.Collections.Generic;

public static class EnumHelper&lt;T&gt;

 public static IList&lt;T&gt; GetValues(Enum value)
 {
 var enumValues = new List&lt;T&gt;();

 foreach (FieldInfo fi in value.GetType().GetFields(BindingFlags.Static | BindingFlags.Public))
 {
 enumValues.Add((T)Enum.Parse(value.GetType(), fi.Name, false));
 }
 return enumValues;
 }

 public static T Parse(string value)
 {
 return (T)Enum.Parse(typeof(T), value, true);
 }

 public static IList&lt;string&gt; GetNames(Enum value)
 {
 return value.GetType().GetFields(BindingFlags.Static | BindingFlags.Public).Select(fi =&gt; fi.Name).ToList();
 }

 public static IList&lt;string&gt; GetDisplayValues(Enum value)
 {
 return GetNames(value).Select(obj =&gt; GetDisplayValue(Parse(obj))).ToList();
 }

 private static string lookupResource(Type resourceManagerProvider, string resourceKey)
 {
 foreach (PropertyInfo staticProperty in resourceManagerProvider.GetProperties(BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Public))
 {
 if (staticProperty.PropertyType == typeof(System.Resources.ResourceManager))
 {
 System.Resources.ResourceManager resourceManager = (System.Resources.ResourceManager)staticProperty.GetValue(null, null);
 return resourceManager.GetString(resourceKey);
 }
 }

 return resourceKey; // Fallback with the key name
 }

 public static string GetDisplayValue(T value)
 {
 var fieldInfo = value.GetType().GetField(value.ToString());

 var descriptionAttributes = fieldInfo.GetCustomAttributes(
 typeof(DisplayAttribute), false) as DisplayAttribute[];

 if (descriptionAttributes.Any() &amp;&amp; descriptionAttributes[0].ResourceType != null)
 return lookupResource(descriptionAttributes[0].ResourceType, descriptionAttributes[0].Name);

 if (descriptionAttributes == null) return string.Empty;
 return (descriptionAttributes.Length &gt; 0) ? descriptionAttributes[0].Name : value.ToString();

I want to contribute with culture-dependent GetDisplayName enum extension. Hope this will be usefull for anyone googling this answer like me previously:

"standart" way as <a href="https://stackoverflow.com/a/25109103">Aydin Adn</a> and <a href="https://stackoverflow.com/a/26455406">Todd</a> mentioned:

<pre><code> public static string GetDisplayName(this Enum enumValue)
 {
 return enumValue
 .GetType()
 .GetMember(enumValue.ToString())
 .First()
 .GetCustomAttribute&lt;DisplayAttribute&gt;()
 .GetName();
 }
</code></pre>

"Culture-dependent" way:

<pre><code> public static string GetDisplayName(this Enum enumValue, CultureInfo ci)
 {
 var displayAttr = enumValue
 .GetType()
 .GetMember(enumValue.ToString())
 .First()
 .GetCustomAttribute&lt;DisplayAttribute&gt;();

 var resMan = displayAttr.ResourceType?.GetProperty(@"ResourceManager", BindingFlags.Static | BindingFlags.Public | BindingFlags.NonPublic).GetValue(null, null) as ResourceManager;

 return resMan?.GetString(displayAttr.Name, ci) ?? displayAttr.GetName();
 }
</code></pre>

+++SendPromotionalByMail+=+0x8
}|code-block|syntax|javascript|448910|然后，如果你想创建一个下拉选择器，你可以使用：|448911|@Html.EnumDropdownListFor(expression:+model+=>+model.PromotionSelector,+optionLabel:+"Select")+|448912|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Using MVC5 you could use:

<pre><code>public enum UserPromotion
{
 None = 0x0,

 [Display(Name = "Send Job Offers By Mail")]
 SendJobOffersByMail = 0x1,

 [Display(Name = "Send Job Offers By Sms")]
 SendJobOffersBySms = 0x2,

 [Display(Name = "Send Other Stuff By Sms")]
 SendPromotionalBySms = 0x4,

 [Display(Name = "Send Other Stuff By Mail")]
 SendPromotionalByMail = 0x8
}
</code></pre>

then if you want to create a dropdown selector you can use:

<pre><code>@Html.EnumDropdownListFor(expression: model =&gt; model.PromotionSelector, optionLabel: "Select") 
</code></pre>

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

My Enum class:

<pre><code>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&lt;DisplayAttribute&gt;()?
 .Name;
 }
}
</code></pre>

My View Model Class:

<pre><code>public class MyViewModel
{
 public Duration Duration { get; set; }
}
</code></pre>

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:

<pre><code>@model IEnumerable&lt;MyViewModel&gt; 

@foreach (var item in Model)
{
 &lt;label asp-for="@item.Duration"&gt;@Enums.GetDisplayName(item.Duration)&lt;/label&gt;
 &lt;div class="form-group"&gt;
 &lt;label asp-for="@item.Duration" class="control-label"&gt;Select Duration&lt;/label&gt;
 &lt;select asp-for="@item.Duration" class="form-control"
 asp-items="Html.GetEnumSelectList&lt;Enums.Duration&gt;()"&gt;
 &lt;/select&gt;
 &lt;/div&gt;
}
</code></pre>

It is maybe cheating, but it's works:

I've got a property in my model called <code>Promotion</code> that its type is a flag enum called <code>UserPromotion</code>. Members of my enum have display attributes set as follows:
<pre><code>[Flags]
public enum UserPromotion
{
 None = 0x0,

 [Display(Name = &quot;Send Job Offers By Mail&quot;)]
 SendJobOffersByMail = 0x1,

 [Display(Name = &quot;Send Job Offers By Sms&quot;)]
 SendJobOffersBySms = 0x2,

 [Display(Name = &quot;Send Other Stuff By Sms&quot;)]
 SendPromotionalBySms = 0x4,

 [Display(Name = &quot;Send Other Stuff By Mail&quot;)]
 SendPromotionalByMail = 0x8
}
</code></pre>
Now I want to be able to create say a <code>ul</code> in my view to show the selected values of my <code>Promotion</code> property. This is what I have done so far but the problem is that how can I get the display names here?
<pre><code>&lt;ul&gt;
 @foreach (int aPromotion in @Enum.GetValues(typeof(UserPromotion)))
 {
 var currentPromotion = (int)Model.JobSeeker.Promotion;
 if ((currentPromotion &amp; aPromotion) == aPromotion)
 {
 &lt;li&gt;Here I don't know how to get the display attribute of &quot;currentPromotion&quot;.&lt;/li&gt;
 }
 }
&lt;/ul&gt;
</code></pre>

How to get the Display Name Attribute of an Enum member via MVC Razor code?

我的模型中有一个名为Promotion的属性，它的类型是一个名为UserPromotion的标志枚举。我的枚举成员的显示属性设置如下：[Flags]public enum UserPromotion{    None = 0x0,    [Display(Name = "Send Job Offers By Mail"...
