How to save the keycode of a pressed key?

Question

I am trying to make a hangman game, but I don't quite know how to handle the input. I would like to have a string that I could then compare to the word the player is guessing.

if (Input.GetKeyDown(KeyCode.A))
{
  answer = "A"
}
else if (Input.GetKeyDown(KeyCode.B))
{
  answer = "B"
}

I know I could just repeat this 13 times but I was wondering if there is a better way of doing things.

Do you want an alternative for the above code? I couldnt understand what you try to achieve — MrJami, Aug 13 '21 at 13:53

@Flydog57I think he is working with unity and he wont work with the console — MrJami, Aug 13 '21 at 13:56
@MrJami Yeah I would love an alternative to my code. And yes I work with unity. — Jan Hrubec, Aug 13 '21 at 14:04
@JonasH That is kind of similar to what I'm after it just seems really complex, will it work in unity though? — Jan Hrubec, Aug 13 '21 at 14:04
@Jan Hrubec, I have no idea about unity. Perhaps [InputString](https://docs.unity3d.com/ScriptReference/Input-inputString.html) is better to use? — JonasH, Aug 13 '21 at 14:35

I actually don't use Unity, but one option is to create Dictionary that maps key codes to strings. Then loop through that:

var codes = new Dictionary<KeyCode, string> {
    {KeyCode.A, "A"},
    {KeyCode.B, "B"},
    ....etc
};
...
foreach(var code in codes)
{
    if (Input.GetKeyDown(code.Key)) {
        answer = code.Value;
        break;
    }
}

Quoting my answer from another question:

You can use Input.anyKeyDown and Input.inputString (case-sensitive):

private void Update()
{
    if( Input.anyKeyDown )
    {
        foreach( char c in Input.inputString )
            answer += char.ToUpperInvariant( c );
    }
}
