Need some help with hangman game in c#.

This is a course project for school and this is what I'm supposed to modify. "This is your final modification to the project. Modify the design and program of the program so that the word is stored as an array. You can use code such as the following: char[] word = "happy".ToCharArray();Where "happy" is replaced with your name. Add a for loop to display each letter in the word character array. If it has been guessed correctly, display the correct letter, if not display the special character." Any help would be appreciated.

Here's the c# code:
insert

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;


namespace ConsoleApp7
{
    class Program
    {
        static void Main(string[] args)
        {
       


            Random random = new Random((int)DateTime.Now.Ticks);


            string[] wordBank = { "Venancio"};
           
            string wordToGuess = wordBank[random.Next(0, wordBank.Length)];
            string wordToGuessUppercase = wordToGuess.ToUpper();


            StringBuilder displayToPlayer = new StringBuilder(wordToGuess.Length);
            for (int i = 0; i < wordToGuess.Length; i++)
                displayToPlayer.Append('*');


            List<char> correctGuesses = new List<char>();
            List<char> incorrectGuesses = new List<char>();
           


            int lives = 10;
            bool won = false;
            int lettersRevealed = 0;
            int score = 10;
            string input;
            char guess;
            while (!won && lives >  0)
            {
                Console.Write("Guess a letter:");


                input = Console.ReadLine().ToUpper();
                guess = input[0];
               
                if (correctGuesses.Contains(guess))
                {
                    Console.WriteLine("You've already tried '{0}', and it was correct!", guess);
                    continue;
                }
                else if (incorrectGuesses.Contains(guess))
                   
                {
                   




                    Console.WriteLine("You've already tried '{0}', and it was wrong! ", guess);
                   








                   










                }
               


                if (wordToGuessUppercase.Contains(guess))
                {
                    correctGuesses.Add(guess);


                    for (int i = 0; i < wordToGuess.Length; i++)
                    {
                        if (wordToGuessUppercase[i] == guess)
                        {
                            displayToPlayer[i] = wordToGuess[i];
                            lettersRevealed++;
                        }
                    }


                    if (lettersRevealed == wordToGuess.Length)
                        won = true;
                }
                else
                {
                   
                    incorrectGuesses.Add(guess);
                 






                    Console.WriteLine("Nope, there's no '{0}' in Ve!", guess);
                   
                  lives--;
                }


                Console.WriteLine(displayToPlayer.ToString());
            }


            if (won)
                Console.WriteLine("You won!");
            else
                Console.WriteLine("You lost! It was '{0}'", wordToGuess);
                Console.WriteLine("You get '{0}' points! ", score);
            score = score + 1;
            Console.Write("Press ENTER to exit...");
            Console.ReadLine();
        }
    }
}

...word is stored as an array.
You can use code such as the following: char[] word = "happy".ToCharArray();Where "happy" is replaced with your name.

You are supposed to create an array of char for your word.

Code:

---

string[] wordBank = { "Venancio"};

---

Why do you create an array of string ?
