Simple Hangman game in C#

Below is a simple implementation of the Hangman game in C#. This code assumes a console-based interaction.

using System;

class HangmanGame
{
    private static readonly string[] WORDS = { "csharp", "programming", "code", "hangman", "computer" };
    private const int MAX_TRIES = 6;

    static void Main()
    {
        Random random = new Random();
        string secretWord = WORDS[random.Next(WORDS.Length)];
        char[] guessedLetters = new char[secretWord.Length];
        int tries = 0;

        while (true)
        {
            DisplayHangman(tries);
            DisplayGuessedWord(guessedLetters);

            Console.WriteLine("Enter a letter: ");
            char guess = Console.ReadKey().KeyChar;

            if (IsLetterAlreadyGuessed(guess, guessedLetters))
            {
                Console.WriteLine("You've already guessed that letter. Try again.");
                continue;
            }

            if (secretWord.Contains(guess))
            {
                UpdateGuessedLetters(secretWord, guessedLetters, guess);
