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;
