序列化时的订单字段

Question

I am xml serializing an object and I cannot seem to change the order in which the fields are serialized.

Ie

public class foo{
string a {get;set;}
string b {get;set;}
}

Comes out as (pseudocode)

<foo b="world" a="hello" />

When I need

<foo a="hello" b="world" />

Can anyone help?

If you cannot achieve this via decorating the class with XML attributes (which you cannot do if you require XML attributes instead of XML elements as output), you may need to implement IXmlSerializable yourself, mentioned briefly here:

custom xml serialization
