任何帮助表示赞赏.谢谢.

Answer 1

我只是遇到了同样的问题...我正在使用

WebSecurity.CreateAccount(model.UserName, model.Password);

以上产生的问题..

然后我尝试：

WebSecurity.CreateAccountAndUser(model.UserName, model.Password);

并发现我缺少用户表（UserProfile）的其他必填字段。以下为我工作：

WebSecurity.CreateAccountAndUser(model.UserName, model.Password, new {RequiredColumn1 = Value1, RequiredColumn2 = Value 2, ...... });

该职位很旧，但是希望可以对其他人有所帮助。

务必：

1. 首先创建用户记录
2. 调用 WebMatrix 创建用户帐户。

下面是我的代码，它解决了您遇到的相同问题：

public ActionResult SignUp(SignUpModel model)
    {
        if (ModelState.IsValid)
        {
            using (MorphometryContext context = new MorphometryContext())
            {
                User user = new User
                {
                    Email = model.Email,
                    FirstName = model.FirstName,
                    LastName = model.LastName,
                    Username = model.UserName
                };
                context.Users.Add(user);
                context.SaveChanges();
            }

            // Attempt to register the user
            try
            {
                WebSecurity.CreateAccount(model.UserName, model.Password);
            }
            catch (MembershipCreateUserException e)
            {
                ModelState.AddModelError("", ErrorCodeToString(e.StatusCode));
                return View();
            }

            WebSecurity.Login(model.UserName, model.Password);
            return RedirectToAction("Index", "Projects");
        }

另外，您不想 Respoonse.Redirect 到 .cshtml 文件。相反，您应该返回 RedirectToAction 并传入操作和控制器名称。
