WCF service, how to mapp the objects runtime

I have to design a wcf service which gives outut in a standard model(which i think its better t开发者_StackOverflow中文版o give as string/XML).But this standard model is/may be subjected to change its format.So every time its changed we need to change the code.My service should also accomadte the same with configurable change. How to do it without code change and exernal configurable entities.

Is there any way to create and mapp the class in runtime.

My primary idea is to keep a format internally and an XML which would be the standard format and to mapp the class properties and XML nodes using a database table.

Please suggest ....Appreciate the help from GURUS !!!

Thanks in advance

I don't fully understand the question, so perhaps you could elaborate upon it, perhaps with some simplified code? However, if you need to map between XML formats, have you considered an XSL Transform?
