CSharp files are not normally found on a GNU/Linux system:

$ locate -r '\.cs$'
/usr/share/aptitude/README.cs
/usr/share/aptitude/aptitude-defaults.cs
/usr/share/emacs/25.2/etc/tutorials/TUTORIAL.cs
/usr/share/geany/filedefs/filetypes.cs
/usr/share/groff/1.22.3/tmac/hyphen.cs
/usr/share/groff/1.22.3/tmac/hyphenex.cs
/usr/share/mc/hints/mc.hint.cs
/usr/share/vim/vim80/tutor/tutor.cs

None of those files are CSharp files, and would get colored wrong
if your syntax were included with nano.

If you wish your syntax to be on https://nano-editor.org/more-syntaxes/,
then please add an author line and a license line.

It would be good to add a comment before each regex to explain what is being
colored by it -- like is done in most syntaxes included with nano.

Using 'white' assumes that the terminal has a dark background, which is not
a good idea for a generally useful syntax.

What if a string contains an escaped double quote (\")?
