        <tr>
            <td>
                @Html.LabelFor(x=>x.Password)
            </td>
            <td>
                @Html.TextBoxFor(x=>x.Password)
            </td>
        </tr>
    </table>
}

解决方案

在您的控制器中，您需要为NEWLOGIN Action添加HTTPGET方法
如下更改控制器...

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using SimpleLogin.Models;
namespace SimpleLogin.Controllers
{
    public class LoginsController : Controller
    {
        //
        // GET: /Logins/

        public ActionResult Index()
        {
            return View();
        }
	[HttpGET]
        public ActionResult NewLogin()
        {
            return View();
        }
        [HttpPost]
        public ActionResult NewLogin(LoginModel m)
        {
            if (m.User_ID == "admin" && m.Password == "pass") 
            {
            
            }
            return View();
        }
    }
}

尝试以下操作:

 [AllowAnonymous]
[HttpPost]
公共 ActionResult NewLogin(LoginModel m)
 {
    如果(m.User_ID == "  span>& m.Password == " )
    {

    }
   返回 View();
 }

解决方案

In your Controller you need to add HTTPGET method for NEWLOGIN Action
Change your controller like below...

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using SimpleLogin.Models;
namespace SimpleLogin.Controllers
{
    public class LoginsController : Controller
    {
        //
        // GET: /Logins/

        public ActionResult Index()
        {
            return View();
        }
	[HttpGET]
        public ActionResult NewLogin()
        {
            return View();
        }
        [HttpPost]
        public ActionResult NewLogin(LoginModel m)
        {
            if (m.User_ID == "admin" && m.Password == "pass") 
            {
            
            }
            return View();
        }
    }
}

Try with following:

[AllowAnonymous]
[HttpPost]
public ActionResult NewLogin(LoginModel m)
 {
    if (m.User_ID == "admin" && m.Password == "pass")
    {

    }
   return View();
 }
