Question : add linq record

I can add a new record using linq in  silverlight. The below works no problem

How do I test first and see if the record exists before inserting it?
If it does exist I need to send back information that the record exists and it it doesnt exists I need to send back the whole new data to reload again.





        Dim mys As two
        mys = New two

        mys.id2 = "qq"
        mys.subject2 = "ww"

        db.twos.InsertOnSubmit(mys)

        db.SubmitChanges()
