如何获得Html的价值。控制器中的下拉列表?

IEnumerable<SelectListItem>

public ActionResult new_vehicle()
{
    ViewBag.customers = db.customers.Select(i=>new SelectListItem() { Text = i.cust_name, Value=i.cust_id });
    return View(db.vehicles.ToList());
}

@Html.DropDownList("customers", (IEnumerable<SelectListItem>)ViewBag.customers, "Select Customer")

然后在你的方法中的控制器中 veh_AddEdit 你可以像这样访问它 Request["customers"]

我希望你能从维克托的回答中得到答案,在这里我想提供更多信息,希望这将有助于更好地理解

前任:

public ActionResult veh_AddEdit(string customers)
    {
        int id = Convert.ToInt32(Request["vehiddenID"]);
        if (id == 0)
        {

            vehicle veh = new vehicle();
            Session["veh_id"] = "";

            veh.cust_id_fk = Convert.ToInt32(customers);
            veh.veh_make = Request["vemake"];
            veh.veh_name = Request["vename"];
            veh.veh_model = Request["vemodel"];
            db.vehicles.Add(veh);
            db.SaveChanges();
            int latestEmpId = veh.veh_id;
        }

        return RedirectToAction("new_vehicle");
    }
