传递到字典中的模型项的类型为'System.Collections.Generic.List`1 [英] The model item passed into the dictionary is of type 'System.Collections.Generic.List`1

问题描述

Server Error in '/' Application.

The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[MVCLoginForm.Models.ModalLogin]', but this dictionary requires a model item of type 'MVCLoginForm.Models.ModalLogin'.

namespace MVCLoginForm.Controllers
{
    public class LoginController : Controller
    {
        //
        // GET: /Login/
        ModalLogin Mod2 = new ModalLogin();
        static List<ModalLogin> Mod = new List<ModalLogin>();
        
        public ActionResult Index()
        {
            return View(Mod);
        }
        public ActionResult Record()  //error in this plz solve
        {
            Mod.Add(Mod2);            //error
            return View(Mod);         //error
        }
        public ActionResult Login()
        {
            return View();
        }
         [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Login(ModalLogin Mod1)
        {
            if (!ModelState.IsValid)
            {
                return View("Login", Mod1);
            }
            Mod.Add(Mod1);
            return RedirectToAction("Index");
        }

    }
}

推荐答案

我认为你犯了同样的错误类型的模型，所以你应该传递视图如

I think you have done same mistake you are passing an list type of model so you should pass in view like

@model List<modallogin>

如果您需要单一型号然后通过

if you need single model then pass

@model modalLogin

如果您想从头学习MVC，可以查看以下链接：

namespace MVCLoginForm.Controllers
{
    public class LoginController : Controller
    {
        //
        // GET: /Login/
        ModalLogin Mod2 = new ModalLogin();
        static List<modallogin> Mod = new List<modallogin>();
        
        public ActionResult Index()
        {
            return View(Mod);
        }
        public ActionResult Record(ModalLogin Mod3) //solved 
        {
            
            return View(Mod3);  //solved        
        }
        public ActionResult Login()
        {
            return View();
        }
         [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Login(ModalLogin Mod1)
        {
            if (!ModelState.IsValid)
            {
                return View("Login", Mod1);
            }
            Mod.Add(Mod1);
            return RedirectToAction("Index");
        }
 
    }
}
