How to save string arrays in Playerprefs 2017?

I’m using Unity version 2017.1.0, and everything I’ve searched says to use ArrayPrefs, ArrayPrefs2, or PlayerPrefsX. But none of those seem to be working in the newer version of unity and there is no updated place where I can find the answer, so if anyone knows how to save a string array into player prefs, that would be amazing. I’m also using C#

Thanks in Advanced.

I imported the ArrayPrefs2 c# script in unity 2017.2.0f3 and it compiled with no errors in.

I used the get/set string arrays without a problem.
