编辑:下面是代码:

public static class EnumEditorHtmlHelper
{
    /// <summary>
    /// Creates the DropDown List (HTML Select Element) from LINQ 
    /// Expression where the expression returns an Enum type.
    /// </summary>
    /// <typeparam name="TModel">The type of the model.</typeparam>
    /// <typeparam name="TProperty">The type of the property.</typeparam>
    /// <param name="htmlHelper">The HTML helper.</param>
    /// <param name="expression">The expression.</param>
    /// <returns></returns>
    public static MvcHtmlString DropDownListFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper,
        Expression<Func<TModel, TProperty>> expression) 
        where TModel : class
    {
        TProperty value = htmlHelper.ViewData.Model == null 
            ? default(TProperty) 
            : expression.Compile()(htmlHelper.ViewData.Model);
        string selected = value == null ? String.Empty : value.ToString();
        return htmlHelper.DropDownListFor(expression, createSelectList(expression.ReturnType, selected));
    }

    /// <summary>
    /// Creates the select list.
    /// </summary>
    /// <param name="enumType">Type of the enum.</param>
    /// <param name="selectedItem">The selected item.</param>
    /// <returns></returns>
    private static IEnumerable<SelectListItem> createSelectList(Type enumType, string selectedItem)
    {
        return (from object item in Enum.GetValues(enumType)
                let fi = enumType.GetField(item.ToString())
                let attribute = fi.GetCustomAttributes(typeof (DescriptionAttribute), true).FirstOrDefault()
                let title = attribute == null ? item.ToString() : ((DescriptionAttribute) attribute).Description
                select new SelectListItem
                  {
                      Value = item.ToString(), 
                      Text = title, 
                      Selected = selectedItem == item.ToString()
                  }).ToList();
    }
}

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

@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" }

})

我遇到了同样的问题，发现了这个问题，并认为Ash提供的解决方案不是我要寻找的;与内置的HTML . dropdownlist()函数相比，必须自己创建HTML意味着更少的灵活性。

c# 3等使得这非常简单。我有一个名为TaskStatus的枚举:

var statuses = from TaskStatus s in Enum.GetValues(typeof(TaskStatus))
               select new { ID = s, Name = s.ToString() };
ViewData["taskStatus"] = new SelectList(statuses, "ID", "Name", task.Status);

这将创建一个很好的ol' SelectList，可以像在视图中一样使用:

<td><b>Status:</b></td><td><%=Html.DropDownList("taskStatus")%></td></tr>

匿名类型和LINQ使它更加优雅。无意冒犯，阿什。：）

更新-我建议使用下面的符文建议，而不是这个选项!

我猜你想要的是下面这样的话:

<select name="blah">
    <option value="1">Movie</option>
    <option value="2">Game</option>
    <option value="3">Book</option>
</select>

你可以用一个扩展方法来做，如下所示:

public static string DropdownEnum(this System.Web.Mvc.HtmlHelper helper,
                                  Enum values)
{
    System.Text.StringBuilder sb = new System.Text.StringBuilder();
    sb.Append("<select name=\"blah\">");
    string[] names = Enum.GetNames(values.GetType());
    foreach(string name in names)
    {
        sb.Append("<option value=\"");
        sb.Append(((int)Enum.Parse(values.GetType(), name)).ToString());
        sb.Append("\">");
        sb.Append(name);
        sb.Append("</option>");
    }
    sb.Append("</select>");
    return sb.ToString();
}

但这类内容是无法本土化的(游戏邦注:即很难将其翻译成其他语言)。

注意:你需要调用静态方法的枚举实例，即Html.DropdownEnum(ItemTypes.Movie);

也许有一种更优雅的方式来做到这一点，但上面的方法确实有效。
