在@html帮助函数中使用枚举显示名称

Question

考虑枚举

  

公共enum教育       {

      [Display(Name="display for education 1")]

    Education1,

    [Display(Name="display for education 2")]
    Education2,

    [Display(Name="display for education 3")]
    Education3,         
}

现在，我希望下拉显示值

 @Html.DropDownListFor(
    model => model.Education,
    new SelectList(@Enum.GetValues(typeof(Education)))  
    new {@class = "default"}
)

我想要显示名称（目前我得到了枚举字符串本身。 有人知道如何在.cshtml中提取它？

看看这个

public static string[] GetEnumDisplays(Type type)
    {
        var displays = new List<string>();
        foreach (FieldInfo f in type.GetFields(BindingFlags.Public | BindingFlags.Static))
        {
            object[] attr = f.GetCustomAttributes(typeof(DisplayAttribute), false);
            if (attr.Length != 0)
            {
                var displayAttribute = (DisplayAttribute)attr[0];
                displays.Add(displayAttribute.Name);
            }
            else
            {
                displays.Add(f.Name);
            }
        }

        return displays.ToArray();
    }
