1-创建ENUM

public enum LicenseType
{
    xxx = 1,
    yyy = 2
}

2-创建您的服务类别

public class LicenseTypeEnumService
    {

        public static Dictionary<int, string> GetAll()
        {

            var licenseTypes = new Dictionary<int, string>();

            licenseTypes.Add((int)LicenseType.xxx, "xxx");
            licenseTypes.Add((int)LicenseType.yyy, "yyy");

            return licenseTypes;

        }

        public static string GetById(int id)
        {

            var q = (from p in this.GetAll() where p.Key == id select p).Single();
            return q.Value;

        }

    }

3-在控制器中设置ViewBag

var licenseTypes = LicenseTypeEnumService.GetAll();
ViewBag.LicenseTypes = new SelectList(licenseTypes, "Key", "Value");

绑定你的下拉列表

@Html.DropDownList("LicenseType", (SelectList)ViewBag.LicenseTypes)

@Html.DropDownListFor(model => model.Type, Enum.GetNames(typeof(Rewards.Models.PropertyType)).Select(e => new SelectListItem { Text = e }))

@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" }

})

谢谢你的解决方案，它可以完美地应用在我的情况。唯一的问题是我必须把它翻译成VB。但现在已经完成了，为了节省其他人的时间(以防他们需要)，我把它放在这里:

Imports System.Runtime.CompilerServices
Imports System.ComponentModel
Imports System.Linq.Expressions

Public Module HtmlHelpers
    Private Function GetNonNullableModelType(modelMetadata As ModelMetadata) As Type
        Dim realModelType = modelMetadata.ModelType

        Dim underlyingType = Nullable.GetUnderlyingType(realModelType)

        If Not underlyingType Is Nothing Then
            realModelType = underlyingType
        End If

        Return realModelType
    End Function

    Private ReadOnly SingleEmptyItem() As SelectListItem = {New SelectListItem() With {.Text = "", .Value = ""}}

    Private Function GetEnumDescription(Of TEnum)(value As TEnum) As String
        Dim fi = value.GetType().GetField(value.ToString())

        Dim attributes = DirectCast(fi.GetCustomAttributes(GetType(DescriptionAttribute), False), DescriptionAttribute())

        If Not attributes Is Nothing AndAlso attributes.Length > 0 Then
            Return attributes(0).Description
        Else
            Return value.ToString()
        End If
    End Function

    <Extension()>
    Public Function EnumDropDownListFor(Of TModel, TEnum)(ByVal htmlHelper As HtmlHelper(Of TModel), expression As Expression(Of Func(Of TModel, TEnum))) As MvcHtmlString
        Return EnumDropDownListFor(htmlHelper, expression, Nothing)
    End Function

    <Extension()>
    Public Function EnumDropDownListFor(Of TModel, TEnum)(ByVal htmlHelper As HtmlHelper(Of TModel), expression As Expression(Of Func(Of TModel, TEnum)), htmlAttributes As Object) As MvcHtmlString
        Dim metaData As ModelMetadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData)
        Dim enumType As Type = GetNonNullableModelType(metaData)
        Dim values As IEnumerable(Of TEnum) = [Enum].GetValues(enumType).Cast(Of TEnum)()

        Dim items As IEnumerable(Of SelectListItem) = From value In values
            Select New SelectListItem With
            {
                .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 Then
            items = SingleEmptyItem.Concat(items)
        End If

        Return htmlHelper.DropDownListFor(expression, items, htmlAttributes)
    End Function
End Module

你可以这样使用它:

@Html.EnumDropDownListFor(Function(model) (model.EnumField))

根据Simon的回答，类似的方法是从Resource文件中获取要显示的Enum值，而不是在Enum本身的描述属性中。如果你的网站需要用多种语言呈现，如果你有一个特定的枚举资源文件，这是很有帮助的，你可以更进一步，在你的Enum中只有Enum值，并从扩展中引用它们，如[EnumName]_[EnumValue] -最终更少的输入!

然后扩展看起来像:

public static IHtmlString EnumDropDownListFor<TModel, TEnum>(this HtmlHelper<TModel> html, Expression<Func<TModel, TEnum>> expression)
{            
    var metadata = ModelMetadata.FromLambdaExpression(expression, html.ViewData);

    var enumType = Nullable.GetUnderlyingType(metadata.ModelType) ?? metadata.ModelType;

    var enumValues = Enum.GetValues(enumType).Cast<object>();

    var items = from enumValue in enumValues                        
                select new SelectListItem
                {
                    Text = GetResourceValueForEnumValue(enumValue),
                    Value = ((int)enumValue).ToString(),
                    Selected = enumValue.Equals(metadata.Model)
                };


    return html.DropDownListFor(expression, items, string.Empty, null);
}

private static string GetResourceValueForEnumValue<TEnum>(TEnum enumValue)
{
    var key = string.Format("{0}_{1}", enumValue.GetType().Name, enumValue);

    return Enums.ResourceManager.GetString(key) ?? enumValue.ToString();
}

枚举中的资源。Resx文件看起来像这样 ItemTypes_Movie:电影

我喜欢做的另一件事是，与其直接调用扩展方法，不如使用@Html调用它。EditorFor(x => x.MyProperty)，或者理想情况下只有整个表单，在一个整洁的@Html.EditorForModel()中。为此，我将字符串模板更改为如下所示

@using MVCProject.Extensions

@{
    var type = Nullable.GetUnderlyingType(ViewData.ModelMetadata.ModelType) ?? ViewData.ModelMetadata.ModelType;

    @(typeof (Enum).IsAssignableFrom(type) ? Html.EnumDropDownListFor(x => x) : Html.TextBoxFor(x => x))
}
