[C#] Screen shot of OpenGL game (Counter-Strike 1.6).

Hey guys. Any ideas on how to take a screenshot of a OpenGL game? Every screen shot I take comes out black.

It only happens while I am ingame - counter-strike 1.6.

I know it is very difficult and many tried this with no success. I found a code over the internet but
I cant make it work: https://pastebin.com/Upsdm08f

Thanks in advance.
