π in C#
I think I'm pretty much doing pi approximations in every language now, so, here it is in C#!
Here are the other approximations so far:

Credit to @NoelBryan, @TheForArkLD , @Warhawk947 , and @LizFoster for inspiring these approximations. Most of these use the Nilakantha Series, although I also use the arctangent method (multiplying the radian arctangent of 1 by 4 to get pi and getting the arctangent with an infinite series) in three of them (Python, Node, and C).
@HahaYes I have a Pi 4 (I think maybe B, I forgot) with 4GB of RAM, but I still have to put an OS on the SD (currently using 32GB, but probably going to upgrade to 128) Unfortunately, Ubuntu MATE doesn't work on my Pi 4 though. I already tried and it didn't work... I even just booted Ubuntu Server, connected to Wifi using commands and USB-added packages to allow those commands to work (don't have Ethernet), and added MATE and it wouldn't work for my monitor. I had to use hdmi_safe as well, so I think it just didn't see the monitor.
