对于MVC v5.1使用Html。EnumDropDownListFor

@Html.EnumDropDownListFor(
    x => x.YourEnumField,
    "Select My Type", 
    new { @class = "form-control" })

对于MVC v5使用EnumHelper

@Html.DropDownList("MyType", 
   EnumHelper.GetSelectList(typeof(MyType)) , 
   "Select My Type", 
   new { @class = "form-control" })

适用于MVC 5及更低版本

我把Rune的答案变成了一个扩展方法:

namespace MyApp.Common
{
    public static class MyExtensions{
        public static SelectList ToSelectList<TEnum>(this TEnum enumObj)
            where TEnum : struct, IComparable, IFormattable, IConvertible
        {
            var values = from TEnum e in Enum.GetValues(typeof(TEnum))
                select new { Id = e, Name = e.ToString() };
            return new SelectList(values, "Id", "Name", enumObj);
        }
    }
}

这允许你这样写:

ViewData["taskStatus"] = task.Status.ToSelectList();

使用MyApp。常见的

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 />

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))

我最终创建了扩展方法来执行这里基本上可以接受的答案。Gist的后半部分专门处理Enum。

我做了以下工作，并取得了成功:

在view.cshtml中:

@ model MyModel.cs

@Html.EnumDropDownListFor(m=>m.MyItemType )

模型中: MyModel.cs

MyItemType {get;设置;｝
