我如何告诉流利的NHibernate没有自动映射忽略特定的属性？ [英] How do I tell Fluent NHibernate to ignore specific properties without automapping?

问题描述

我正在使用流利NHibernate映射出一个现有的数据库。出于这个原因 - 自动映射不是我的选择。

我如何告诉NHibernate不映射某些属性？其中许多是只读的，而其他的则不需要被其他原因持久化。

我在VB.Net中写这个。

我得到了典型的错误信息：
以下类型不能用作代理
...应该是public / protected virtual或protected internal我有意不让我的对象Overridable（相当于C＃中的虚拟），因为我不希望NHibernate触摸它们。

b

我该如何做到这一点？

解决方案

所有属性和方法必须被覆盖才能使NHibernate创建动态代理，包括未映射的属性。这并不意味着NHibernate映射你的只读属性，它只是要求它们被覆盖，以便它可以生成类的代理。 本文解释了这一要求。 p>

I am using Fluent NHibernate to map out an existing database. For this reason - automapping isn't an option for me.

How do I tell NHibernate not to map certain properties? Many of them are read-only, and the others do not need to be persisted for other reasons.

I am writing this in VB.Net.

I get the typical error message: "The following types may not be used as proxies ... should be 'public/protected virtual' or 'protected internal virtual'"

I have purposely not made my objects Overridable (equivalent to virtual in C#) because I do not want NHibernate to touch them.

How can I achieve this?

解决方案

All properties and methods must be overridable in order for NHibernate to create dynamic proxies, including unmapped properties. This does not imply that NHibernate is mapping your read-only properties, it just requires them to be overridable so that it can generate a proxy of the class. This article explains the requirement.
