首先,我向各位展示了我所做的事,现在的情况是存在的。 我在伙伴关系中的项目。 NET MVC 3.
这是表格业务的模式。
[Table("Business")]
public class Business
{
[Key]
public long? BusinessId { get; set; }
public Int32 LegalTypeId { get; set; }
public Int16 BusinessTypeId { get; set; }
public Int64 OwnerId { get; set; }
public Int32 MainIndustryFieldId { get; set; }
public String NameNative { get; set; }
public String NameEnglish { get; set; }
public Byte[] Logo { get; set; }
public DateTime CreateDate { get; set; }
public virtual User Owner { get; set; }//It is Forign key with user table
}
[Table("User")]
public class User
{
[Key]
public Int64 UserId { get; set; }
public String UserName { get; set; }
public String LoweredUserName { get; set; }
public String FirstName { get; set; }
public String LastName { get; set; }
public String Email { get; set; }
public String LoweredEmail { get; set; }
public String Password { get; set; }
public String PasswordSalt { get; set; }
public String PasswordQuestion { get; set; }
public String PasswordAnswer { get; set; }
public Boolean IsApproved { get; set; }
public Boolean IsLocked { get; set; }
public DateTime LastActivityDate { get; set; }
public DateTime LastLoginDate { get; set; }
public DateTime CreateDate { get; set; }
public virtual Business Bussines { get; set; }
}
当我想补充信息时:
user.Business = new Business
{
OwnerId = user.UserId,
LegalTypeId = business.LegalTypeId,
BusinessTypeId = business.BusinessTypeId,
MainIndustryFieldId = business.MainIndustryFieldId,
NameNative = business.NameNative,
NameEnglish = business.NameEnglish,
Logo = business.Logo,
CreateDate = DateTime.Now
};
ctx.SaveChanges();
我有以下错误:
Cannot insert explicit value for identity column in table Business when IDENTITY_INSERT is set to OFF.
在数据库栏目中,选定身份识别业务为<代码>实体是。
Somebody can tell what to do.
