MVC使用:

Controller

 List<ListItem> listItems = EnumHelper.GetListItemByEnum(typeof(FeedbackStatus), true);//包含请选择用true
            ViewBag.StatusData = new SelectList(listItems, "Value", "Text"); 

view

 @Html.DropDownList("Search", (SelectList)ViewBag.StatusData, new { @class = "form-control input-sm" })//下拉框赋值

var strStatus = Vector.Framework.Tool.EnumHelper.Value2Text<FeedbackStatus>(entity.StatusId);//数据表存的数字转化为枚举串
