How do I create a loop for a c# hangman game?

I've made this hangman game but the only problem is I can't figure out which simple loops (For,While, or Do While) I should use to make the program give the user three chances to answer correctly or keep on repeating if they do answer correctly. I was wondering if anyone could guide me in the right direction?

        Console.WriteLine("Do you want to play a game?");
        string answer = Console.ReadLine();

        if (answer == "no")
        {
            Console.WriteLine("Please Exit Program");
        }


        System.Threading.Thread.Sleep(1000);
        if (answer == "yes")
        {   
            Console.WriteLine(" ");
            Console.WriteLine("Welcome to Hangman");

            string[] array1 = new string[10];
            array1[0] = "hello";
            array1[1] = "swami";
            array1[2] = "zebra";
            array1[3] = "rainbow";
            array1[4] = "camp";
            array1[5] = "unicycle";
            array1[6] = "trivia";
            array1[7] = "hockey";
            array1[8] = "charlie";
            array1[9] = "canada";

            Random word = new Random();

            int mynumber = word.Next(0, 10);

            char[] array2 = array1[mynumber].ToCharArray();


            char[] array3 = new char[array2.Length];

            Console.WriteLine(array2);

            for (int i = 0; i < array2.Length; i++)
            {
                array3[i] = '*';
            }

            Console.WriteLine(" ");
            Console.WriteLine(array3);

            System.Threading.Thread.Sleep(1500);

            Console.WriteLine(" ");
            int number = 1;
            number = number + 1;

            Console.WriteLine(" Guess a letter");
            char letter = Char.Parse(Console.ReadLine());
            Console.WriteLine(" ");

            for (int i = 0; i < array2.Length; i++)
            {
                if (letter == array2[i])
                {
                    Console.Write(letter);
                }
                else
                {
                    Console.Write("*");
                }                    
            }               

            Console.WriteLine(" ");
        }        
    }
}
