which version?
in v2.0 you can do a custom ResourceProvider.
here is a howto for v1.x
http://www.openmymind.net/index.aspx?documentId=52
if it is just one time export you can use the System.Resources.ResXResourceReader and
System.Resources.ResXResourceWriter
or just the Xml Dom( XmlDocument, DataSet class. The resx structure is so simple that any of these would work.
HTH!
