Question

I have the following table:

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

I need to map it to the object:

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

Where, StronglyTypedData is something like:

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

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.

What do I need to do to accomplish this?

Answer 1

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

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