save string from array to player prefs

How do I save a string from an array into player prefs and then reload that string back into the same array slot later on?

I thought it was was this but nope??

// Letters To Remember
    public string[] CharsToRemember = new string[5];

private void Start()
        PlayerPrefs.GetString("CharacterToRem", CharsToRemember[0].ToString());
        Debug.Log("Characters Saved Loaded To Array");

// Add Character To "CharsToRemember" Array
    public void AddChar_A()
        sresult += "A";

string sresult = "";
    IEnumerator ListenForInputSequenceUntilDone()
        // Wait Time
        yield return new WaitForSeconds(1.5f);
        // Reset String For New inputs
        sresult = "";
        while (true)
            if (LettersToRemIsDone == true) break;

            string sval = Input.inputString;
            if (!string.IsNullOrEmpty(sval))
                sresult += sval;
            yield return null;
        CharsToRemember[0] = sresult;
        PlayerPrefs.SetString("CharacterToRem", CharsToRemember[0].ToString());
        Debug.Log("Character Saved To Player Prefs");


Not sure I fully understand the goal/problem, but if you want to store 5 strings (as indicated in the code), I would just use 5 uniquely named preference keys (ex: “s1”, “s2”, “s3”, “s4”, “s5”). Trying to pack multiple pieces of distinct data in one preference property can often result in parsing errors and be tougher to maintain the code. As for your code, it looks like CharsToRemember (in the ListenForInputSequenceUntilDone method) is always setting array index 0. Should this be incrementing instead of always setting CharsToRemember[0] value?
