XPathDocument - file stays open

[jenlion]

I have a new service that watches a directory for new xml files and takes action when one is added/changed.

When I add the following code, I find that once I save a file in the watched directory, I'm no longer able to access it. My service has it locked up.

Offending code:

Dim xpathDoc As XPathDocument
        Dim xmlNav As XPathNavigator
        xpathDoc = New XPathDocument(FileName)
        xmlNav = xpathDoc.CreateNavigator()

        Dim payloadID As String
        Dim timeStamp As String
        Dim xmlNI As XPathNodeIterator
        xmlNI = xmlNav.Select("/cXML")
        xmlNI.MoveNext()
        xmlNav = xmlNI.Current
        payloadID = xmlNav.GetAttribute("payloadID", "")
        timeStamp = xmlNav.GetAttribute("timestamp", "")

I'm looking for some way to force this to release the file, but not finding it. It works fine for getting the values I need, but I'd kind of like to have my file back later. Someone may want to modify and save it again. Currently, it's only released if I stop the service.

Do you set all of the objects to Nothing when you are done with them?

Yes, I did try that, thanks.

(I should be more specific. I did try that, and it didn't fix it. )
