ASP.NET MVC用存储过程批量添加修改数据操作

public ActionResult MarketTaskAdd()
  {
   var markeType = new MarketDataProvider().GetBTIDData().Where(a=>a.ID!="0");//读取类别
   var rel = new MarketTaskProgressProvider().GetMarketMonthTask();
   if (rel.Count() > 0)
   {
    ViewBag.datas = rel.Join(markeType, a => a.MKBTID, b => int.Parse(b.ID), (a, b) => new { a.MKBTID, b.ID,b.Text,a.TaskNum }).Select(s=>new ViewsModel { ID= s.MKBTID.ToString() ,Text=s.Text,TaskNum=s.TaskNum.ToString()}); }//如果有数据关联数据
   else
   {
    var rel2 = markeType.Select(s => new ViewsModel{ ID = s.ID, Text = s.Text, TaskNum="" }).ToList();//直接返回表单
    ViewBag.datas = rel2;
   }
   return View();
  }

@foreach (var modelMarkets in ViewBag.datas)
       {
        <div class="row" style="margin-top:10px">
         <div class="col-md-4 text-right"><span class="red">*</span> @modelMarkets.Text </div>
         <div class="col-md-8 text-left">
          <input name="text|@modelMarkets.ID" class="form-control" style="width:50%" value="@modelMarkets.TaskNum" type="text" />
          <input type="hidden" name="type|@modelMarkets.ID" value="type|@modelMarkets.ID" /><!--隐藏表单-->
         </div>
        </div>
       }
