How to save an array to PlayerPrefs?

I know about PlayerPrefsX ( but I don’t know how to save something like this to it:

var storage = new Array("box", "table", "chair");

Whenever I try PlayerPrefsX.SetStringArray, I get errors. I tried just PlayerPrefsX.SetArray, but that didn’t work either. Is there a way to save an array like this?

I don’t really know JS/US, but this should be correct:

var storage = ["box", "table", "chair"];
PlayerPrefsX.SetStringArray ("Storage", storage);

Just to be safe, the C# Version:

var storage = new string[] { "box", "table", "chair" };
PlayerPrefsX.SetStringArray ("Storage", storage);
