我正在尝试使用DbFirst方法在.net核心上创建用户注册表单。 我在数据库中创建了一个表。使用用户身份验证（内置身份）创建.net核心项目。然后我做了脚手架。用适当的值填充字段并发布请求后，出现以下错误：
处理请求时发生未处理的异常。
SqlException：无效的列名'AccessFailedCount'。无效的栏 名称为“ ConcurrencyStamp”。无效的列名“ LockoutEnabled”。无效 列名“ LockoutEnd”。无效的列名“ NormalizedEmail”。 无效的列名“ NormalizedUserName”。无效的列名 “密码哈希”。无效的列名“ PhoneNumber”。无效的列名 “电话号码已确认”。无效的列名“ SecurityStamp”。无效 列名称“ TwoFactorEnabled”。无效的列名“ UserName”。
DbUpdateException：更新条目时发生错误。看到 内部异常以获取详细信息。
上述字段位于名为IdentityUser（我从中继承的那个）的只读文件中。它是只读的，所以我不能从中删除任何字段。
这是我的注册IActionResult：
[HttpPost]
public async Task<IActionResult> Register(RegisterViewModel model, string returnUrl = null)
{
ViewData["ReturnUrl"] = returnUrl;
var errors = ModelState.Where(c => c.Value.Errors.Count > 0).Select(c => c.Value).ToList();
if (ModelState.IsValid)
{
var user = new User
{
Name = model.Name,
Email = model.Email,
Address = model.Address,
PersonalId = model.PersonalId,
Country = model.Country,
MobilePhone = model.MobilePhone,
BirthDate = model.BirthDate,
};
_context.User.Add(user);
_context.SaveChanges();
var result = await _userManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
var callbackUrl = Url.Action("ConfirmEmail", "Home", new { userId = user.Id, code = code }, protocol: HttpContext.Request.Scheme);
return RedirectToAction("RegisterConfirm");
}
}
return View(model);
}
我正在猜测，问题在于 IdentityUser 中提到的字段为空，这就是为什么我收到错误消息，但也许我错了。 User.cs
public partial class User :IdentityUser<int>
{
public int Id { get; set; }
public string Country { get; set; }
public string PersonalId { get; set; }
public string MobilePhone { get; set; }

public DateTime BirthDate { get; set; }
public string Password { get; set; }
public string Name { get; set; }
public string Address { get; set; }
public byte[] Idimage { get; set; }
public bool? EmailConfirmed { get; set; }
public bool? Smsconfirmed { get; set; }
}

更新：刚刚发现我在数据库中看不到身份表。我猜这是另一个问题。
