asp.net-mvc - 名称不能为 null 或为空。 asp.net 身份 mvc 5 + EntityFreamwork

Question

有人遇到过这样的问题吗？他向我抛出错误:名称不能为空或为空。但表中没有名为“Name”的属性。我想自定义 Asp.Net Identity。

Controller

  public class HomeController : Controller
{
    //
    // GET: /Home/
    public async Task<ActionResult> Index()
    {
        var userStore = new UserStore<User,Identity_2Context.MyRole,long,Identity_2Context.MyUserLogin,Identity_2Context.MyUserRole,Identity_2Context.MyClaim>(new Identity_2Context());
        var manager = new UserManager<User,long>(userStore);

        var user = new User()
        {
            UserName = "TehnoMac",Email = "TehnoMac@tehcno.com",IsApproved = true,IsLockedOut = false,
            CreatedDate = DateTime.Now,LastActivityDate = DateTime.Now,LastLoginDate = DateTime.Now,FailedPasswordAnswerAttemptCount = 0,
            FailedPasswordAttemptCount = 0
        };

        var result = await manager.CreateAsync(user, "test123test");

        if (result.Succeeded)
        {
            var authenticationManager = HttpContext.GetOwinContext().Authentication;
            var userIdentity = manager.Create(user, DefaultAuthenticationTypes.ApplicationCookie);
        }
        else
        {
            ViewBag.Text = result.Errors.FirstOrDefault();
        }

        return View();
    }
}

身份模型公共(public)类ApplicationUser:IdentityUser { }

public class MyClaim:IdentityUserClaim<long>
{
}

public class MyRole:IdentityRole<long,MyUserRole>
{
}

public class MyUserRole:IdentityUserRole<long>
{
}
public class MyUserLogin:IdentityUserLogin<long>
{
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser,MyRole,long,MyUserLogin,MyUserRole,MyClaim>
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }
}

Answer 1

确保您已指定用户名。我遇到了同样的错误，设置 UserName 属性后，错误消失了。
