C#.NET MVC 枚举转dictionary自动装载生成下拉框

 
 /// <summary>
    /// 枚举转SelectListItem
    /// </summary>
    public class Enum_Helper
    {
        /// <summary>  
        /// 枚举转字典集合  
        /// </summary>  
        /// <typeparam name="T">枚举类名称</typeparam>  
        /// <param name="keyDefault">默认key值</param>  
        /// <param name="valueDefault">默认value值</param>  
        /// <returns>返回生成的字典集合</returns>  
        public static List<SelectListItem> GetSelectListItem<T>(object keyDefault)
        {

            List<SelectListItem> dicEnum = new List<SelectListItem>();
            Type enumType = typeof(T);
            if (!enumType.IsEnum)
                return dicEnum;

            string[] fieldstrs = Enum.GetNames(enumType); //获取枚举字段数组  
            foreach (var item in fieldstrs)
            {
                string description = string.Empty;
                var field = enumType.GetField(item);
                object[] arr = field.GetCustomAttributes(typeof(DescriptionAttribute), true); //获取属性字段数组  
                if (arr != null && arr.Length > 0)
                    description = ((DescriptionAttribute)arr[0]).Description;   //属性描述  
                else
                    description = item;  //描述不存在取字段名称  

                //判断是否添加默认选项  
                if (keyDefault != null && keyDefault.Equals(Enum.Parse(enumType, item)))
                {

                    dicEnum.Add(new SelectListItem() { Text = description, Selected = true, Value = Enum.Parse(enumType, item).ToString() });
                }
                else
                {
                    dicEnum.Add(new SelectListItem() { Text = description, Value = Enum.Parse(enumType, item).ToString() });
                }

            }
            return dicEnum;
        }


    }

调用 Enum_Helper.GetSelectListItem<HealthLederses.Auditing>(input.HealthLedersAuditDto.Status);
