DropDownList 绑定的俩种写法

前台界面view 视图

@using (Html.BeginForm("Index", "CustomerInformation", FormMethod.Get)){                  <p>客户名称: @Html.TextBox("SearchString")  <br />              风险级别: @Html.DropDownList("dow_riskLevel_C","") @Html.Hidden("dow_riskLevel")              入围情况: @Html.DropDownList("dow_finalistCase_C","") @Html.Hidden("dow_finalistCase")              客户策略: @Html.DropDownList("dow_customerStrategy_C","") @Html.Hidden("customerStrategy_C")              省份: @Html.DropDownList("dow_province_C","") @Html.Hidden("province_C")

         <input type="submit" value="查找" id="selectBtn"/></p>  } 

后台Controller 数据组织用 俩种方式 组织绑定

            //风险级别下拉框 数据整理 去掉重复项            var dow_riskLevel_C = from dr in db.DownSet                                  where dr.modelName == "客户信息" && dr.modelField == "风险级别"                                  select dr.modelvalue;            dow_riskLevel_C = dow_riskLevel_C.Distinct();            ViewBag.dow_riskLevel_C = new SelectList(dow_riskLevel_C, "modelvalue");
            //入围情况下拉框 数据整理 去掉重复项            var dow_finalistCase_C = from df in db.DownSet                                     where df.modelName == "客户信息" && df.modelField == "入围情况"                                     select df.modelvalue;            dow_finalistCase_C = dow_finalistCase_C.Distinct();            List<SelectListItem> items = new List<SelectListItem>();            foreach (var item in dow_finalistCase_C)            {                items.Add(new SelectListItem { Text = item, Value = item });            }            ViewBag.dow_finalistCase_C = items;
