LINQ -Tried to get a count to see if query returned anything

The query results cannot be enumerated more than once
and the routine died on line
73:         Next

what I am trying to do is see if I've returned a recordset and, if not, instead of showing results, show a message to the effect that no results were returned.

I am VERY new to LINQ, watched videos on it, can't find the syntax to bind to a list (I saw the video, cannot FIND it again)... not even sure if I should try to bind to a list.

thanks for any help
