XMLReader keeps file open...

[CharlieIT]

I am using the code below to open and read an xml file which is located on a remote computer. It does this fine, but once the code is executed, the XML file on the remote machine stays "open"--I cannot delete it, rename it, etc. because of a sharing violation.

I have executed "reader.Close" and "Stream.Close", but they do not close the file.

Any Ideas?

Dim Time As String

Try
' open the document...

Dim filestream As New System.IO.FileStream("\\" &_ machineName & "\" & "d$\Dat.xml", IO.FileMode.Open)

Dim reader As New XmlTextReader(filestream)

' move to the start of the document...
reader.MoveToContent()

' ignore whitespaces
reader.WhitespaceHandling = WhitespaceHandling.None

' start working through the document...
Do While reader.Read

' what kind of node is it?
Select Case reader.NodeType

' is it the start of an element?
Case XmlNodeType.Element

' if it's an element start, is it "logontime"?
If reader.Name = "logontime" Then

'If so, then read the value of the element
reader.ReadStartElement()
Time = reader.Value
End If

End Select
Loop

filestream.Close()
reader.Close()
Return Time

Catch ex As Exception
Time = ex.Message
End Try


End Function

Are you hitting your exception?

Are you calling Dispose on your objects?

Objects that deal with files are using unmanaged resources, and so you have to wait for the garbage collector to run. By calling Dispose (on objects that implement IDisposable) you don't have this delay.
