Stargate SG-1 S7E9 "Avenger 2.0"

In this episode, Dr. Felger comes up with a virus that is able to remotely disable stargates. After it doesn't go as planned, Sam comes in to help and we see this montage that involves writing code on a whiteboard.
I thought it was sort of silly how she wasn't just brainstorming pseudocode here, which is generally the type of thing that I see coders doing with whiteboards. No, that seems to be a full verbose script, written character-for-character. But as I looked closer, it got worse. That language seems to be C#. If we take this situation as literal as possible, that must mean the SGC had come up with some .NET-like middleware framework sort of thing for interacting with the stargate. I would imagine that there were better languages that they could have used instead.
That is probably the most egregious thing about this. Any time someone is brainstorming code on a whiteboard, semicolons are the first thing to go. You can add them when it comes time to type the code into the computer, but they're superfluous for brainstorming.
