问题描述
我遇到这个错误，它没有提供任何详细的根本原因是什么，但我想通了什么问题。我想分享它，以便其他人遇到它可能在解决问题的成功。
我有以下类：
公共类BankUser：IdentityUser，IUserProfile
{
＃区域IUserProfile成员
[显示（名称=名）]
公共字符串名字{获得;组; } [显示（名称=姓氏）]
公共字符串名字{获得;组; } [需要]
[显示（名字=电子邮件地址）
[EmailAddress的（的ErrorMessage =电子邮件地址无效）]
公共字符串电子邮件{获得;组; } [显示（NAME =时区）]
公众诠释的TimeZone {搞定;组; }
公共字典＆LT;字符串，字符串＆GT; TimeZoneOptions
{
得到
{
字典＆LT;字符串，字符串＆GT; D =新词典＆LT;字符串，字符串＆GT;（）;
d.Add（（GMT -10：00）夏威夷，-10）;
d.Add（（GMT -9：00）阿拉斯加，-9）;
d.Add（（GMT -8：00）太平洋时间，-8）;
d.Add（（GMT -7：00）山地时间，-7）;
d.Add（（GMT -6：00）中部时间，-6）;
d.Add（（GMT -5：00）东部时间，-5）;
d.Add（未知，0）;
返回D组;
}
} [显示（NAME =手机）]
[电话（的ErrorMessage =无效的电话号码。）]
[StringLength（10，MinimumLength = 10的ErrorMessage =电话号码必须是10个字符长。）]
公共字符串电话{搞定;组; }
#endregion
}
正如你所看到的，我伸出IdentityUser具有附加属性。我的观点只是想创建一个新用户 UserManager.CreateAsync（）当有用户名和密码表单域。当试图只用用户名和密码提交表单系统将尝试验证，因为它有必需的属性，电子邮件传递。
//
// POST：/帐号/注册
[HttpPost]
[使用AllowAnonymous]
[ValidateAntiForgeryToken]
公共异步任务＆LT;＆的ActionResult GT;寄存器（RegisterViewModel模型）
{
如果（ModelState.IsValid）
{
VAR用户=新BankUser（）{用户名= model.UserName};
VAR的结果=等待UserManager.CreateAsync（用户，model.Password）;
如果（result.Succeeded）
{
等待SignInAsync（用户，isPersistent：假）;
返回RedirectToAction（指数，家）;
}
其他
{
AddErrors（结果）;
}
} //如果我们走到这一步，事情失败了，重新显示形式
返回查看（模型）;
}
解决方案
我必须添加电子邮件作为我的表单字段或删除必需属性。有一次，我做了他们俩的code和预期一样。
希望有所帮助。
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.
I had the following class:
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
}
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);
}
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.
Hope that helps.
