Apart from the fact that your C# sample uses integer math via random.next(), you're also getting the wrong answer when overflow inevitably occurs. ;-) Whereas the VFP sample is using floating point math and will throw an error if overflow occurs.

Not sure why this sort of trickshot is re-ignited along with the spiteful antagonism that we'd managed to avoid for a while. We all know it's possible to generate examples that "prove" one language is better than another. for example, it's still easy enough to kill a C# app (and the machine it's on) by generating vast datasets that spooled invisibly to disk in FP for 2 decades in my experience with little effect on performance. So? People who need spooling can continue using VFP. People who don't perceive spooling value can move to C#. It's a big wide world with plenty of variability, thank goodness.

In this case, lets all accept that C# is better than VFP in every respect. Cool. Now what about Python/Ruby, since the OP asked about those specifically? That might be an interesting discussion, especially since participants aren't like to start being "amused" at each other (which IME is a label for gratuitous spite showing anything but humor).
