出现错误时但又找不到错误在哪里？可以尝试下面的，try catch语句，能清楚的找到error. try            {                Repository
     
       superAdmin = new Repository
      
       (context);                AllUsers usr = new AllUsers();                usr.Id = "1";                usr.Name = "admin";                usr.Password = "sineva";                usr.IsSuper = true;                usr.Description = "系统内置";                usr.IsRCurrent = true;                superAdmin.Add(usr);                context.SaveChanges();                base.Seed(context);            }            catch(DbEntityValidationException ex)            {                 StringBuilder errors = new StringBuilder();                IEnumerable
       
         validationResult = ex.EntityValidationErrors;                foreach (DbEntityValidationResult result in validationResult)                {                    ICollection
        
          validationError = result.ValidationErrors;                    foreach (DbValidationError err in validationError)                    {                        errors.Append(err.PropertyName + ":" + err.ErrorMessage + "\r\n");                    }                }                    Console.WriteLine(errors.ToString());            }
