I'm unable to find a solution to lowercase my input. C#

namespace Quiz { class Program { static void Main(string[] args) { int score = 0;

        Console.WriteLine("What is 5 + 5");
        Console.WriteLine("A) 2 B) 10 C) 20");



        if (Console.ReadLine() == "B")
        {
            Console.WriteLine("Good Job!");
            score++;
        }



        Console.WriteLine("What is 6 + 6");
        Console.WriteLine("A) 2 B) 10 C) 12");

        if (Console.ReadLine() == "C")
        {
            Console.WriteLine("Good Job!");
            score++;
        }

        Console.WriteLine("What is 7 + 7");
        Console.WriteLine("A) 14 B) 10 C) 12");

        if (Console.ReadLine() == "A")
        {
            Console.WriteLine("Good Job!");
            score++;
        }
        Console.WriteLine("Your score is: {0}", score);
        Console.ReadLine();

    }

}

}

I'm trying to have if(Console.ReadLine() == "C" || "b") { Console.WriteLine("Good Job!"); score++ }

I'm not sure how to get this to work though. I've tried doing .ToLower as well but it doesn't seem to work. Or maybe I'm just doing it wrong, Idk. If anyone could help that'd be great.

The "ToLower" is a good idea, but be sure you compare it only with lower-case strings!

Also, when you combine tests with boolean logic, each side of the combiner must be a complete expression:

// so instead of this:
    if (Console.ReadLine() == "C" || "b")
// you would need something like this:
    var answer = Console.ReadLine().ToLower();
    if (answer == "c" || answer == "b")
