在ASP.Net Identity（MVC）中的“注册”期间保存其他配置文件数据

我需要在用户注册期间存储其他信息，例如：名字，姓氏等。

我的问题有两个部分：

1. 如何在注册期间保存我的附加信息？
2. 我当前的方法抛出错误：

一个或多个实体的validation失败。 有关详细信息，请参阅“EntityValidationErrors”属性 。 我已经在VS内部检查了“Watch”，并且还使用了try-catch，但它没有帮助。

在此先感谢您的帮助！

IdentityModels.cs

public class ApplicationIdentityAccount : IdentityUser { public virtual ICollection AccountProfiles { get; set; } } public class AccountProfile { [Key] public string AccountProfileID { get; set; } [DisplayName("First Name")] [StringLength(50)] [Required(ErrorMessage = "First name is required")] public string FirstName { get; set; } [DisplayName("Middle Name")] [StringLength(50)] public string MiddleName { get; set; } [DisplayName("Last Name")] [StringLength(50)] [Required(ErrorMessage = "Last name is required")] public string LastName { get; set; } public string UserId { get; set; } [ForeignKey("UserId")] public virtual ApplicationIdentityAccount User { get; set; } } public class ApplicationIdentityDbContext : IdentityDbContext { public ApplicationIdentityDbContext() : base("ApplicationIdentity", throwIfV1Schema: false) { } public static ApplicationIdentityDbContext Create() { return new ApplicationIdentityDbContext(); } public System.Data.Entity.DbSet AccountProfile { get; set; } } 

AccountViewModels.cs> RegisterViewModel

  public class RegisterViewModel { [Required] [Display(Name = "Username")] public string UserName { get; set; } [Required] [Display(Name = "First Name")] public string FirstName { get; set; } [Required] [Display(Name = "Last Name")] public string LastName { get; set; } [Required] [EmailAddress] [Display(Name = "Email")] public string Email { get; set; } [Required] [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)] [DataType(DataType.Password)] [Display(Name = "Password")] public string Password { get; set; } [DataType(DataType.Password)] [Display(Name = "Confirm password")] [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")] public string ConfirmPassword { get; set; } } 

AccountController.cs

 [HttpPost] [AllowAnonymous] [ValidateAntiForgeryToken] public async Task Register(RegisterViewModel model) { if (ModelState.IsValid) { var user = new ApplicationIdentityAccount { UserName = model.UserName, Email = model.Email, AccountProfile = new[] {new AccountProfile() { FirstName = model.FirstName, LastName = model.LastName }} }; var result = await UserManager.CreateAsync(user, model.Password); if (result.Succeeded) { await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false); // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771 // Send an email with this link // string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id); // var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme); // await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking here"); return RedirectToAction("Index", "Home"); } AddErrors(result); } // If we got this far, something failed, redisplay form return View(model); } 

我知道我应该在其中放置FirstName和LastName ：

 var user = new ApplicationIdentityAccount { UserName = model.UserName, Email = model.Email, };

由于您的问题包含两部分：

1. 您存储其他信息的方法是正确的

2. 除非您看到实际错误，否则无法继续操作，以便在创建用户的位置查看需要添加的详细信息。

    public override int SaveChanges() { try { return base.SaveChanges(); } catch (DbEntityValidationException ex) { // Retrieve the error messages as a list of strings. var errorMessages = ex.EntityValidationErrors .SelectMany(x => x.ValidationErrors) .Select(x => x.ErrorMessage); // Join the list to a single string. var fullErrorMessage = string.Join("; ", errorMessages); // Combine the original exception message with the new one. var exceptionMessage = string.Concat(ex.Message, " The validation errors are: ", fullErrorMessage); // Throw a new DbEntityValidationException with the improved exception message. throw new DbEntityValidationException(exceptionMessage, ex.EntityValidationErrors); } }
