Then you should use Dictionary type.

private Dictionary<string, string> guessAnswerDict = new Dictionary<string, string>();

private void Start()
{
    guessAnswerDict["test1"] = "answer1";
    guessAnswerDict["test2"] = "answer2";
}

You can check whether the test exists in Dictionary with

guessAnswerDict.Contains("test1");

And get the answer value with

var answer = guessAnswerDict["test1"];

It will throw an exception when there are no key in dictionary, so you have to check it with Contains.

Of course you can merge these two with TryGetValue, like

string answer;
guessAnswerDict.TryGetValue("test1", out answer);

// Totally identical!!
guessAnswerDict.TryGetValue("test1", out var answer);

TryGetValue will return false if there are no key in the dictionary.

BTW, although C#'s default access modifier is private, it's always good to explicitly write it's private, which will increase the readability of your code :)
