推荐答案

drop.cshtml代码

drop.cshtml Code

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
    var listItems = new List<SelectListItem>();
    listItems.Add(new SelectListItem { Text = String.Empty, Value = String.Empty });
    foreach (var name in ViewBag.Names)
    {
        listItems.Add(new SelectListItem { Text = name, Value = name });
    }
}
<h2>
    Index</h2>
@Html.DropDownList("dropDownList", listItems)

控制器:

Controller:

public ActionResult drop()
      {
          List<string> abc=new List<string>(2);
          var q = from a in objContext.Details
                  select a;
          foreach (var i in q)
          {
              abc.Add(i.Name);
          }
          ViewBag.Names = abc;
          return View(q);
      }
