    LazySerializer

    Lazily serializes an object to XML for usage in XPath/XSLT.

    Lazily serializes an C# object to XML for usage in XPath/XSLT. For example: _________________________________________ ObjectXmlNavigator nav = new ObjectXmlNavigator("myObject", MyObject); XslTransform xslTrans = new XslTransform(); xslTrans.Transform(nav, null, objStream); _________________________________________ Using the ObjectXmlNavigator object you can now access the properties of MyObject in your XSLT. Only properties (or properties of properties) that your reference in your XSLT will be 'converted' to XML, hence the 'Lazy' serializer.
