我的应用出现以下错误:
An exception of type 'System.Data.Entity.Validation.DbEntityValidationException' occurred in EntityFramework.dll but was not handled in user code
Additional information: Validation failed for one or more entities. See 'EntityValidationErrors' property for more details.
我在尝试注册新用户时遇到此错误。 “db.SaveChanges()”发生错误
代码如下:
public ActionResult Registration(x.Models.User user)
{
if(ModelState.IsValid)
{
using(var db = new xDBEntities1())
{
var crypto = new SimpleCrypto.PBKDF2();
var encrpPass = crypto.Compute(user.password);
var sysUser = db.users.Create();
sysUser.email = user.email;
sysUser.username = user.username;
sysUser.password = encrpPass;
sysUser.premium_credits = 0;
sysUser.login_times = 0;
sysUser.last_ip = Request.ServerVariables["REMOTE_ADDR"];
sysUser.creation_ip = Request.ServerVariables["REMOTE_ADDR"];
sysUser.banned = 0;
sysUser.creation_date = DateTime.Now;
sysUser.creation_time = DateTime.Now.TimeOfDay;
db.users.Add(sysUser);
db.SaveChanges();
}
}
return RedirectToAction("Index", "Home");
}
编辑: 用户模型类
public class User
{
[Required]
[StringLength(50)]
[Display(Name="Username: ")]
public String username { get; set; }
[Required]
[DataType(DataType.Password)]
[StringLength(50,MinimumLength=6)]
[Display(Name="Password: ")]
public string password { get; set; }
[Required]
[EmailAddress]
[StringLength(50)]
public string email { get; set; }
public int phonenumber { get; set; }
public int mobilephonenumber { get; set; }
}
}
我该如何处理？
