Pex and "\ 0", what is it right for?

Question

I use Pex and keep throwing "\ 0" in my string parameters. Through a little testing, did I find this to be some end of line?

I'm looking for an official name for this to find out more about this, but google puts all the white spaces in "\ 0", which makes it 0, and the end of the line doesn't show up either.

Interestingly, the length of the lines is "\ 0", the length is 1, the display is "" \ 0 \ 0 ", the length is 2, the display is" "1234 \ 056709", the length is 10, the display is "1234"

thanks for the tips

Answer 1

Null-terminated string

Answer 2

\ 0 - escape for the NUL character.
