Concantanate them using the & character.

you can't use the & concat method in c#. you have to use +
You really should be concating them at the database anyway...less load on your app . like this:

SELECT field1 + ' ' + field2 AS BothFields FROM TABLE

then, when you bind (i'm assuming you're binding), bind to 'BothFields'
