How to conditionally serialize properties to xml based on a custom attribute?

I have a complex object graph which I need to serialize to Xml. On each and every property I've added a custom attribute:

public class ExportLevelAttribute : Attribute

public ExportLevel Values get; set;

public ExportLevelAttribute (params ExportLevel values)

this.Values = values;




and on each property:

[ExportLevel(Simple, Normal, Detailed)]
public bool IsTest get; set;

[ExportLevel(Detailed)]
public SomeObject1 Property1 get; set;

[ExportLevel(Normal, Detailed)]
public SomeObject2 Property2 get; set;


The object graph is populated from corresponding database tables and there's no differentiation of the export level whilst populating, ie. all and any data in the tables is used to map to the object's properties.

It's the responsibility of the serializing method to determine which properties end up in the xml.

I looked at OnSerializing() and was wondering if it would work. Is it possible to access the property's attribute within the method? Or is there a better way to conditionally serialized properties?
