Entity Framework插入数据报错：Validation failed for one or more entities. See 'EntityValidationErrors' property for more details.

stackoverflow的解决方法

        try
        {
            db.Entity.Add(entity);
            db.SaveChanges();
        }
        catch (DbEntityValidationException dbEx)
        {
            foreach (var validationErrors in dbEx.EntityValidationErrors)
            {
                foreach (var validationError in validationErrors.ValidationErrors)
                {
                    System.Console.WriteLine("Property: {0} Error: {1}", validationError.PropertyName, validationError.ErrorMessage);
                }
            }
        }

通过调试可以明确的知道哪个字段有问题

如果包含了导航属性，可以查看导航属性的数据，

比如id，那就必须对比下，具体是哪个出了问题
