使用默认User.Identity.getUserName（）从AspNetUsers表获取电子邮件到另一个视图（从另一个表）并禁用该字段

Question

我有一个ASP.NET MVC 5应用程序，其中用户（雇主）​​注册从默认的帐户/注册操作中输入电子邮件和密码，然后重定向（如果成功）到另一个操作（雇主/创建）。

我在项目中有一个雇主模型（Employer.cs），其中包含电子邮件作为其中一个属性。当显示视图（雇主/创建）时，我希望禁用电子邮件字段，但仍然显示来自AspNetUsers表（用于注册的表）的电子邮件，以便用户无法输入与AspNetUsers表中的一个。

这是我的代码：

帐户/注册

@using (Html.BeginForm("Register", "Account", FormMethod.Post, new { @class = "form-group", role = "form" }))
            {
                <div class="col-md-4" id="log">
                    <h3>Register</h3>
                    @Html.AntiForgeryToken()
                    <h4>Create a new account.</h4>
                    @Html.ValidationSummary("", new { @class = "text-danger" })
                    <div class="form-group">
                        @Html.TextBoxFor(m => m.Email, new { placeholder = "Email", @class = "form-control, textbox" })
            }

和雇主/创建

    @using (Html.BeginForm("Create", "Employer", null, FormMethod.Post, new { enctype = "multipart/form-data" }))
    {
        @Html.AntiForgeryToken()

        <div class="col-md-6" id="log">
            <h3>Welcome</h3>
            <h4>Kindly create a profile to connect with talented techies</h4>
            <hr />
            @Html.ValidationSummary(true, "", new { @class = "text-danger" })
            <div class="form-group">
                @Html.TextBoxFor(model => model.Email, htmlAttributes: new { @class = "form-control,text-box", placeholder = "Email address", value=TempData["Email"], @readonly ="readonly" })
                @Html.ValidationMessageFor(model => model.Email, "", new { @class = "text-danger" })
            </div>
        </div>
   }

和雇主控制器

public ActionResult Create([Bind(Include = "ID,CompanyName,Email,CompanyWebsite,Address,Field")] Employer employer)
        {
            employer.Email = User.Identity.GetUserName();
            TempData["Email"] = employer.Email;
            try
            {
                if (ModelState.IsValid)
                {
                    db.Employers.Add(employer);
                    db.SaveChanges();
                    return RedirectToAction("Details", "Employer", new { Message = ManageController.ManageMessageId.CreateProfileSuccess, id = Model.ID  });
                }
            }
           ...
        }

我尝试使用TempData，但无济于事。我该如何上班？

注册操作：

         public async Task<ActionResult> Register(RegisterViewModel model)
                    {
                        using (var context = new ApplicationDbContext())
                            if (ModelState.IsValid)
                        {
                            var user = new ApplicationUser { UserName = model.Email, Email = model.Email };
                            var result = await UserManager.CreateAsync(user, model.Password);
                            var roleStore = new RoleStore<IdentityRole>(context);
                            var roleManager = new RoleManager<IdentityRole>(roleStore);
                            var userStore = new UserStore<ApplicationUser>(context);
                            var userManager = new UserManager<ApplicationUser>(userStore); 
        userManager.AddToRole(user.Id, "Employer");
        if (result.Succeeded)
                            {
                                await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);
                               ...
                             return RedirectToAction("Create", "Employer");
                            }
                            AddErrors(result);
                        }
                       // If we got this far, something failed, redisplay form
                      return View(model);
                   }

创建操作的HttpGet请求

public ActionResult Create()
        {
            return View();
        }
