I am working on a business object that will contain a root object and several child objects. All these objects are rolled together into a JSON or XML string for saving in the database. The object contains a list of custom fields that the user would like to be displayed on a profile/survey.
I'm trying to determine what would be the best approach for serializing and deserializing this object. My choices are:
If I use the DataContractSerializer classes, what would happen to the various state flags and events that fire when a business object is changed?
Any thoughts/suggestions?
Thanks

If you just want to persist your BO as xml, I'd just go with creating an XDocument in your DP_IU methods and having the children add their values to this document.
I wouldn't store the result of DCS or DCJS; serialization is meant to move an object across the wire only, not to put it in a form for persistence. you'll hit versioning problems attempting this, and possible loss of data.
Actually DCS and DCJS are not overly version sensitive - not like BinaryFormatter or NDCS or MobileFormatter. So it isn't uncommon to use DCS for primitive persistence.
The thing is, CSLA business objects can't be directly serialized/deserialized using DCS/DCJS - you really need to define a formal set of contract types (DTOs) and serialize them.
Thank you Rocky.
If I use the DataMapper class, will it be able to walk the object graph?
DataMapper does not walk an object graph, no. It maps one object to another.
