WriteXML, but not to file system

Dim xwriter As Xml.XmlWriter = Nothing
Dim dt As New DataTable("AuditLog")
'fill dt with one row
dt.WriteXml("M:\Migrate\dtSchemaData.xml", XmlWriteMode.WriteSchema)
'works
dt.WriteXml(xwriter, XmlWriteMode.WriteSchema) 'does nothing
Dim str As String = Nothing
str = xwriter.ToString 'fails, null reference

The line above fails, but the first WriteXml to a file works. Can anyone
explain why?

Thanks,
Dean S
