Hello everyone,


I am writing XQuery based on an XML file. I am using instance type of XPathDocument, XPathNavigator, XPathExpression and  XPathNodeIterator.

My question is does any of them need to be released to free resource? I have not found any Close/Dispose methods for them. It is so strange to me since at least the XML file to be queried needs to be closed.


thanks in advance,
George
