这里是Martin Faartoft的变种，你可以放自定义标签，这对本地化很好。

public static class EnumHtmlHelper
{
    public static SelectList ToSelectList<TEnum>(this TEnum enumObj, Dictionary<int, string> customLabels)
        where TEnum : struct, IComparable, IFormattable, IConvertible
    {
        var values = from TEnum e in Enum.GetValues(typeof(TEnum))
                     select new { Id = e, Name = customLabels.First(x => x.Key == Convert.ToInt32(e)).Value.ToString() };

        return new SelectList(values, "Id", "Name", enumObj);
    }
}

视图中使用:

@Html.DropDownListFor(m => m.Category, Model.Category.ToSelectList(new Dictionary<int, string>() { 
          { 1, ContactResStrings.FeedbackCategory }, 
          { 2, ContactResStrings.ComplainCategory }, 
          { 3, ContactResStrings.CommentCategory },
          { 4, ContactResStrings.OtherCategory }
      }), new { @class = "form-control" })
@Html.ValidationMessageFor(m => m.Category)

你也可以在Griffin.MvcContrib中使用我的自定义HtmlHelpers。以下代码:

@Html2.CheckBoxesFor(model => model.InputType) <br />
@Html2.RadioButtonsFor(model => model.InputType) <br />
@Html2.DropdownFor(model => model.InputType) <br />

我找到的最好的解决办法就是把这个博客和西蒙·戈德斯通的答案结合起来。

这允许在模型中使用枚举。从本质上讲，这个想法是使用整数属性和枚举，并模拟整数属性。

然后使用[System.ComponentModel。属性用于用你的显示文本注释模型，并在你的视图中使用“EnumDropDownListFor”扩展。

这使得视图和模型都非常可读和可维护。

模型:

public enum YesPartialNoEnum
{
    [Description("Yes")]
    Yes,
    [Description("Still undecided")]
    Partial,
    [Description("No")]
    No
}

//........

[Display(Name = "The label for my dropdown list")]
public virtual Nullable<YesPartialNoEnum> CuriousQuestion{ get; set; }
public virtual Nullable<int> CuriousQuestionId
{
    get { return (Nullable<int>)CuriousQuestion; }
    set { CuriousQuestion = (Nullable<YesPartialNoEnum>)value; }
}

观点:

@using MyProject.Extensions
{
//...
    @Html.EnumDropDownListFor(model => model.CuriousQuestion)
//...
}

            Type realModelType = modelMetadata.ModelType;

            Type underlyingType = Nullable.GetUnderlyingType(realModelType);
            if (underlyingType != null)
            {
                realModelType = underlyingType;
            }
            return realModelType;
        }

        private static readonly SelectListItem[] SingleEmptyItem = new[] { new SelectListItem { Text = "", Value = "" } };

        public static string GetEnumDescription<TEnum>(TEnum value)
        {
            FieldInfo fi = value.GetType().GetField(value.ToString());

            DescriptionAttribute[] attributes = (DescriptionAttribute[])fi.GetCustomAttributes(typeof(DescriptionAttribute), false);

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

            else
                return value.ToString();
        }

        public static MvcHtmlString EnumDropDownListFor<TModel, TEnum>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TEnum>> expression)
        {
            return EnumDropDownListFor(htmlHelper, expression, null);
        }

        public static MvcHtmlString EnumDropDownListFor<TModel, TEnum>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TEnum>> expression, object htmlAttributes)
        {
            ModelMetadata metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
            Type enumType = GetNonNullableModelType(metadata);
            IEnumerable<TEnum> values = Enum.GetValues(enumType).Cast<TEnum>();

            IEnumerable<SelectListItem> items = from value in values
                                                select new SelectListItem
                                                {
                                                    Text = GetEnumDescription(value),
                                                    Value = value.ToString(),
                                                    Selected = value.Equals(metadata.Model)
                                                };

            // If the enum is nullable, add an 'empty' item to the collection
            if (metadata.IsNullableValueType)
                items = SingleEmptyItem.Concat(items);

            return htmlHelper.DropDownListFor(expression, items, htmlAttributes);
        }
    }
}

我想以一种不同的方式回答这个问题，用户不需要在控制器或Linq表达式中做任何事情。这种方式……

我有一个ENUM

public enum AccessLevelEnum
    {
        /// <summary>
        /// The user cannot access
        /// </summary>
        [EnumMember, Description("No Access")]
        NoAccess = 0x0,

        /// <summary>
        /// The user can read the entire record in question
        /// </summary>
        [EnumMember, Description("Read Only")]
        ReadOnly = 0x01,

        /// <summary>
        /// The user can read or write
        /// </summary>
        [EnumMember, Description("Read / Modify")]
        ReadModify = 0x02,

        /// <summary>
        /// User can create new records, modify and read existing ones
        /// </summary>
        [EnumMember, Description("Create / Read / Modify")]
        CreateReadModify = 0x04,

        /// <summary>
        /// User can read, write, or delete
        /// </summary>
        [EnumMember, Description("Create / Read / Modify / Delete")]
        CreateReadModifyDelete = 0x08,

        /*/// <summary>
        /// User can read, write, or delete
        /// </summary>
        [EnumMember, Description("Create / Read / Modify / Delete / Verify / Edit Capture Value")]
        CreateReadModifyDeleteVerify = 0x16*/
    }

现在我可以使用这个enum简单地创建一个下拉列表。

@Html.DropDownList("accessLevel",new SelectList(AccessLevelEnum.GetValues(typeof(AccessLevelEnum))),new { @class = "form-control" })

OR

@Html.DropDownListFor(m=>m.accessLevel,new SelectList(AccessLevelEnum.GetValues(typeof(AccessLevelEnum))),new { @class = "form-control" })

如果你想让一个索引被选中，那么试试这个

@Html.DropDownListFor(m=>m.accessLevel,new SelectList(AccessLevelEnum.GetValues(typeof(AccessLevelEnum)) , AccessLevelEnum.NoAccess ),new { @class = "form-control" })

这里我使用了AccessLevelEnum。NoAccess作为默认选择下拉菜单的额外参数。

好吧，我真的是姗姗姗迟了，但无论如何，我已经在博客上讨论了这个主题，在这个主题中我创建了一个EnumHelper类，它可以实现非常简单的转换。

http://jnye.co/Posts/4/creating-a-dropdown-list-from-an-enum-in-mvc-and-c%23

在你的控制器中:

//If you don't have an enum value use the type
ViewBag.DropDownList = EnumHelper.SelectListFor<MyEnum>();

//If you do have an enum value use the value (the value will be marked as selected)    
ViewBag.DropDownList = EnumHelper.SelectListFor(MyEnum.MyEnumValue);

在您看来:

@Html.DropDownList("DropDownList")
@* OR *@
@Html.DropDownListFor(m => m.Property, ViewBag.DropDownList as SelectList, null)

helper类:

public static class EnumHelper
{
    // Get the value of the description attribute if the   
    // enum has one, otherwise use the value.  
    public static string GetDescription<TEnum>(this TEnum value)
    {
        var fi = value.GetType().GetField(value.ToString());

        if (fi != null)
        {
            var attributes = (DescriptionAttribute[])fi.GetCustomAttributes(typeof(DescriptionAttribute), false);

            if (attributes.Length > 0)
            {
                return attributes[0].Description;
            }
        }

        return value.ToString();
    }

    /// <summary>
    /// Build a select list for an enum
    /// </summary>
    public static SelectList SelectListFor<T>() where T : struct
    {
        Type t = typeof(T);
        return !t.IsEnum ? null
                         : new SelectList(BuildSelectListItems(t), "Value", "Text");
    }

    /// <summary>
    /// Build a select list for an enum with a particular value selected 
    /// </summary>
    public static SelectList SelectListFor<T>(T selected) where T : struct
    {
        Type t = typeof(T);
        return !t.IsEnum ? null
                         : new SelectList(BuildSelectListItems(t), "Text", "Value", selected.ToString());
    }

    private static IEnumerable<SelectListItem> BuildSelectListItems(Type t)
    {
        return Enum.GetValues(t)
                   .Cast<Enum>()
                   .Select(e => new SelectListItem { Value = e.ToString(), Text = e.GetDescription() });
    }
}

@Html.DropDownListFor(model => model.MaritalStatus, new List<SelectListItem> 
{  

new SelectListItem { Text = "----Select----", Value = "-1" },


new SelectListItem { Text = "Marrid", Value = "M" },


 new SelectListItem { Text = "Single", Value = "S" }

})
