Question

好吧我很浪费太多时间试图完成这个目标而且我有点沮丧，我想做的就是这样：

**表aspNetUserRoles 用户身份角色ID

表aspNetRole 角色ID
RoleName **

我已经完成了第一部分，我已经使用种子方法填充了aspNetUserRoles，并在我的数据库中有一些角色，我已经创建了一个包含我所有角色的下拉列表，但是当我按下Register时遇到问题我得到一个错误：＆＃34;未找到UserId＆＃34;我将在这里展示我做了什么，并将放置我的2张桌子

我做了什么

 [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegisterViewModel model)
    {
        if (ModelState.IsValid)
        {
            var user = new ApplicationUser { UserName = model.Email, Email = model.Email, Sobre = model.Sobre, Idade = model.Idade, Telemóvel = model.Telemóvel, Nome = model.Nome };
            var result = await UserManager.CreateAsync(user, model.Password);
            var roleStore = new RoleStore<IdentityRole>(db);
            var roleManager = new RoleManager<IdentityRole>(roleStore);

            var userStore = new UserStore<ApplicationUser>(db);
            var userManager = new UserManager<ApplicationUser>(userStore);
            userManager.AddToRole(user.Id, "Name");

            if (result.Succeeded)
            {
                await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);

                // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
                // Send an email with this link
                // string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
                // var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
                // await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>");

                return RedirectToAction("Index", "Home");
            }
            AddErrors(result);
        }

        // If we got this far, something failed, redisplay form
        return View(model);
    }

如果有人能让我解释我做错了什么我非常感激：）

使用像这样

if (result.Succeeded)
{
userManager.AddToRole(user.Id, "Name");
}

向AspNetUserRoles添加角色
