如何使用NHibernate将XML类型列映射到强类型对象属性? [英] How to map XML type column to a strongly typed object property with NHibernate?

问题描述

我有下表:

CREATE TABLE [dbo].[Data] (
    [Id]            UNIQUEIDENTIFIER NOT NULL,
    [Data]   XML              NOT NULL,
);

我需要将其映射到对象:

I need to map it to the object:

class Data
{
    public virtual Guid Id {get; set;}
    public virtual StronglyTypedData Data {get; set;}
}

其中StronglyTypedData类似于:

Where, StronglyTypedData is something like:

class StronglyTypedData
{
    public string Name {get; set;}
    public int Number {get; set;}
}

默认情况下，XML列映射到XmlDocument属性，但我希望XML序列化/反序列化到StronglyTypedData属性发生在映射时.

By default, XML columns are mapped to XmlDocument properties, but I would like XML serialization/deserialization to StronglyTypedData property to happen instead at mapping time.

我需要怎么做才能做到这一点?

What do I need to do to accomplish this?

推荐答案

您需要编写一个负责转换的IUserType.

You need to write an IUserType that takes care of the conversion.

您可以从 XmlDocType ，实际上是从原始XML转换为XmlDocument的那个.

You could start from XmlDocType, which is the one actually converting from raw XML to a XmlDocument.
