asp.net mvc中是否存在登录和注册的问题？

问题描述 投票：0回答：1

我是一个学习MVC的学生。

我只有一个表用于登录和注册。

问题是登录不起作用以及注册不起作用

“在此处输入图像描述”

stanstuds.cs

    public class stanstuds
    {
        [Key]
        public int id { get; set; }

        public string fname { get; set; }

        public string mname { get; set; }

        public string lname { get; set; }

        public string country { get; set; }

        public string usertype { get; set; }

        public string username { get; set; }

        public string password { get; set; }
    }

上下文类

     public class stanstudcontext:DbContext
    {
        public stanstudcontext():base("cnnos")
        {

        }

        public DbSet<stanstuds> studs { get; set; }
    }

控制器

public class LogRegController : Controller
    {
        stanstudcontext context = new stanstudcontext();

        //admin view just I print the sample message this is an admin view
        public ActionResult Index()
        {
            return View();
        }

        //client view just I print the sample message this is a client view
        public ActionResult Clientview()
        {
            return View();
        }
        //Login
        [HttpGet]
        public ActionResult Login()
        {
            return View();
        }

        [HttpPost]
        public ActionResult Login(stanstuds studs)
        {
            var userdata=context.studs.Where(x => x.username == studs.username && x.password == studs.password).FirstOrDefault();
            if (userdata != null)  //when i m debugging this condition is not check
            {
                  // i have a 2 records of admin in database but when i run time enter that record login is not working 
                if (userdata.usertype == "admin")   
                {
                    return RedirectToAction("Index", "LogReg");
                }
                else
                {
                    return RedirectToAction("Clientview", "LogReg");
                }

            }
            else
            {

                return View();
            }
        }

        //Registration 
        public ActionResult Regis()
        {
            return View();
        }

        [HttpPost]
        public ActionResult Regis(stanstuds studs)
        {
            context.studs.Add(studs);
            context.SaveChanges();
            return View();
        }

        var userdata=context.studs.Where(x => x.username.Equals(studs.username)).FirstOrDefault();
            if (userdata != null)
            {
                    if (userdata.Password == userdata.Password) //success
                    {
                        HttpContext.Session.SetInt32("id", userdata.id);
                        return RedirectToAction("Index", "Home");
                    }
