问题描述

我遇到了这个错误，它没有提供任何关于根本原因的详细信息，但我想出了问题所在.我想分享它，以便其他遇到它的人可以成功解决问题.

I encountered this error, it did not provide any detail as to what the root cause was but I figured out what the problem is. I wanted to share it so that others that encounter it might have success in solving the problem.

我有以下课程:

    public class BankUser : IdentityUser, IUserProfile
{
    #region IUserProfile Members
    [Display(Name = "First Name")]
    public string FirstName { get; set; }

    [Display(Name = "Last Name")]
    public string LastName { get; set; }

    [Required]
    [Display(Name = "Email Address")]
    [EmailAddress(ErrorMessage="Invalid Email Address")]
    public string Email { get; set; }

    [Display(Name = "Time Zone")]
    public int TimeZone { get; set; }
    public Dictionary<string, string> TimeZoneOptions
    {
        get
        {
            Dictionary<string, string> d = new Dictionary<string, string>();
            d.Add("(GMT -10:00) Hawaii", "-10");
            d.Add("(GMT -9:00) Alaska", "-9");
            d.Add("(GMT -8:00) Pacific Time", "-8");
            d.Add("(GMT -7:00) Mountain Time", "-7");
            d.Add("(GMT -6:00) Central Time", "-6");
            d.Add("(GMT -5:00) Eastern Time", "-5");
            d.Add("Unknown", "0");
            return d;
        }
    }

    [Display(Name = "Phone")]
    [Phone(ErrorMessage = "Invalid phone number.")]
    [StringLength(10, MinimumLength = 10, ErrorMessage = "Phone number must be 10 characters long.")]
    public string Phone { get; set; }
    #endregion
}

如您所见，我使用其他属性扩展了 IdentityUser.在尝试创建新用户 UserManager.CreateAsync() 时，我的视图只有用户名和密码作为表单字段.当尝试仅使用用户名和密码提交表单时，系统会尝试验证电子邮件是否已通过，因为它具有必需属性.

As you can see, I extended IdentityUser with additional properties. My view only had UserName and Password as form fields when trying to create a new user UserManager.CreateAsync(). When trying to submit the form with just the UserName and Password the system would try to validate that Email was passed since it had the Required attribute.

        //
    // POST: /Account/Register
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegisterViewModel model)
    {
        if (ModelState.IsValid)
        {
            var user = new BankUser() { UserName = model.UserName };
            var result = await UserManager.CreateAsync(user, model.Password);
            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);
    }

推荐答案

解决方案我必须将电子邮件添加为表单中的字段或删除必需属性.一旦我做了其中任何一个，代码就会按预期工作.

Solution I must either add the Email as a field in my form or remove the Required attribute. Once I did either of them the code worked as expected.
