visual stidio #if on visual studio version

I want to compile different thing based on the visual studio version i'm using, something like

#if VISUAL_STUDIO_VERSION > 2015
eventH?.Invoke(this, EventArgs.Empty);
#else
if(eventH != null)
  eventH(this, EventArgs.Empty);
#endif

how can i do this?

i tried something like

#if (_MSC_VER==1700)

based on this with no luck
