How to make a inputfield ignore if it's normal or capital letters.

Is it possible to make it so I can answer with both capital letters and normal letters. That If you Wright the answer like this “ArMy oF tWo” it just as right as “army of two” Her is the script for the InputField. Thanks in Advance :)---------------------
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using UnityEngine.SceneManagement;

public class ArmyOfTwo: MonoBehaviour {

private string gameName;

private int countGuess;

[SerializeField]
private InputField input;

[SerializeField]
private Text text;

void Awake(){
	gameName = "army of two";
	text.text = "Guess The Name Of The Game";
}
public void GetInput(string guess){
	CompareGuesses(guess);
	input.text = "";
}
public void CompareGuesses (string guess){
	if (guess == gameName) {
		text.text = "You Guessed Correctly";
		SceneManager.LoadScene("Level 1");
	} else if (guess != gameName) {
		text.text = "Wrong!";
	} else if (guess != gameName) {
		text.text = "Wrong!";
	}
}

}

Hi, did you tried to convert your string to lowercase with the toLower() function?
Like following:

public void CompareGuesses (string guess){
     if (guess.ToLower() == gameName.ToLower()) {
         text.text = "You Guessed Correctly";
         SceneManager.LoadScene("Level 1");
     } else if (guess.ToLower() != gameName.ToLower()) {
         text.text = "Wrong!";
     } else if (guess.ToLower() != gameName.ToLower()) {
         text.text = "Wrong!";
     }
 }

convert everything to lowercase or uppercase before comparing

string test1 = "HelLLo WOrlD"
string test2 = "hELLO woRLd"

bool equals = test1.ToLower() == test2.ToLower()
