arrays - GetUpperBound vs UBound for speed -

which faster? i've tried googling , couldn't find remotely helpful settle on own. best got simple dotnetfiddle: https://dotnetfiddle.net/i6yx6r

ubound calls array.getupperbound internally, implementation near identical:

public function ubound(byval array system.array, optional byval rank integer = 1) integer          if (array nothing)             throw vbmakeexception(new argumentnullexception(getresourcestring(resid.argument_invalidnullvalue1, "array")), vberrors.outofbounds)          elseif (rank < 1) orelse (rank > array.rank)             throw new rankexception(getresourcestring(resid.argument_invalidrank1, "rank"))          end if          return array.getupperbound(rank - 1)      end function 

this obtained microsoft's reference source.

the difference between 2 sure immeasurable, suspect ubound ever slow since bounds checking, first.

in reality, because actual implementations same, use whichever more comfortable using stylistically.
