NHibernate缺少重写属性的SqlParameter

我正在尝试使用FluentNHibernate自动映射实现逐层次表的方法。
我有一个基类和三个子类。第三个子类重写基类的两个属性。前两个子类的实例可以很好地保存，但是当我试图用重写的属性保存第三个类的实例时，我得到了

Invalid index 7 for this SqlParameterCollection with Count=7.

NHibernate似乎没有为重写的属性添加SqlParameters，但它尝试设置一个值

如何解决这个问题？可能在映射/配置方面有一些更改

是，FluentNHibernate自动映射为覆盖的属性添加重复映射。
奇怪的是，代码没有帮助

.Override<ThirdClass>(map => { map.IgnoreProperty(p => p.Age); }) 

.Override（map=>{map.IgnoreProperty（p=>p.Age）；}）

所以我必须使用

.OverrideAll(map => map.IgnoreProperties(x => x.MemberInfo.HasAttribute<IgnoreMapAttribute>()))

.OverrideAll（map=>map.IgnoreProperties（x=>x.MemberInfo.HasAttribute（））

---

并在我的类中设置[IgnoreMap]属性。

我想您已经尝试过用谷歌搜索该错误消息了？有相当多的谷歌点击，包括许多这样的问题和答案。两种常见的解决方案似乎是不可空类型和重复映射。谢谢你，Jamie！是的，我试过用谷歌搜索这个问题的主题——没用
