There are a number of options, here are a few:-
You could add references to your buttons to a hashtable with a unique value
to identify them, and then do a lookup on this from the sender argument of
your event handler.
You could use Chris's code sample for determining the control name at
runtime:-

Finally you could derive your own control from Button and add a Name, Tag or
similar property which you can use to uniquely identify each one. However
there will be a bit of extra work required to create designer support for
the control.
