C#.NET MVC 枚举转dictionary自动装载生成下拉框

 

 /// <summary>
    /// 枚举转SelectListItem

    public class Enum_Helper
    {
        /// <summary>

        {

            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

            {
                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 > )
                    description = ((DescriptionAttribute)arr[]).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);
