C# problem (the program dosn't reconize x when I put it in

Console.WriteLine("Type in 1,2 or x");
            char c = Console.ReadLine()[0];
            c = char.ToUpper(c);
            if (c== '1')
            {
                Console.WriteLine("Your option is {0}", c);
                Console.ReadKey();
            }//(c == '1')
            else if (c== '2')
            {
                Console.WriteLine("Your option is {0}", c);
                Console.ReadKey();
            }//(c == '2')
            else if (c.Equals('x'))
            {
                Console.WriteLine("Your option is {0}", c);
                Console.ReadKey();
            }//(c == 'x')
            else
            {
                Console.WriteLine("1,2 or x Only !");
                Console.ReadKey();
            }//else
            Console.WriteLine("Goodbye");
            Console.ReadKey();

(c== 'x')

(c.Equals('x'))
