Adding a role for user after registration in MVC 5
提问by SKale
I want to add newly registered user to a generic "User" role in my application. I am using ASP.NET Identity. My code below returns a cryptic error - Exception Details: System.Configuration.Provider.ProviderException: The role '' was not found.
我想将新注册的用户添加到我的应用程序中的通用“用户”角色。我正在使用 ASP.NET 标识。我下面的代码返回一个神秘的错误 - 异常详细信息：System.Configuration.Provider.ProviderException：找不到角色“”。
Do I need to instantiate something in my account controller (role manager etc)? Here my code in the AccountController Register POST action.
我是否需要在我的帐户控制器（角色管理器等）中实例化某些内容？这是我在 AccountController Register POST 操作中的代码。
// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
if (ModelState.IsValid)
{
var user = new ApplicationUser() { UserName = model.UserName };
var result = await UserManager.CreateAsync(user, model.Password);
var person = new Person() {
UserName = user.UserName,
UserId = user.Id,
LastName = model.LastName,
FirstName = model.FirstName,
Email = model.Email,
PhoneCell = model.PhoneCell };
Roles.AddUserToRole(model.UserName, "User");
if (result.Succeeded)
{
await SignInAsync(user, isPersistent: false);
db.People.Add(person);
db.SaveChanges();
return RedirectToAction("Index", "Home");
}
else
{
AddErrors(result);
}
}
// If we got this far, something failed, redisplay form
return View(model);
}

You need to use UserManagerto add role to the user. See below:
您需要使用UserManager向用户添加角色。见下文：
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
using (var context = new ApplicationDbContext())
{
if (ModelState.IsValid)
{
var user = new ApplicationUser() { UserName = model.UserName };
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, "User");
if (result.Succeeded)
{
await SignInAsync(user, isPersistent: false);
return RedirectToAction("Index", "Home");
}
else
{
AddErrors(result);
}
}
// If we got this far, something failed, redisplay form
return View(model);
}
}

If you're using the built in authentication manager and Account Controller then this wil do it:
如果您使用内置的身份验证管理器和帐户控制器，则可以这样做：
UserManager.AddToRole(user.Id, "<Role>");
