Cannot print an array of char to the console. It prints system.char[] instead of the actual letters

So basically im doing a hangman game printing the results directly on the console. Ive got everything working, last step is printing my array variable m_WordToDisplay which contains all of the guessed letters with the underscores for the spaces not guessed yet.

Every time the user makes a correct guess, i want to debug.log or print m_WordToDisplay, but when i do so, what it reads on the console instead of the actual word (ie. w__d), instead it reads System.Char[]

I know my variable m_WordToDisplay has the word stored in it because when i step into the code i see the guessed letter and the underscores. so the problem seems to really be just when printing the actual result. Here is my code which is relevant:

     private char[] m_WordToDisplay;

My initialize method where i choose the word and then fill in the array with underscores:

     public void InitializeGame (Player player, int numberOfMistakesAllowed = 6){
         if (player == null){
             Debug.Log ("ma player is null");
         }
         if (m_numberOfMistakesAllowed < 0){
             Debug.Log ("number of mistakes must be non negative");
         }
         m_Player = player;
 
         LoadWordList();
 
         m_numberOfMistakesAllowed = numberOfMistakesAllowed;
         Outcome = Outcome.InProgress;
         Word = ChooseWord ();
         m_WordToDisplay = new char [this.Word.Length];
         for (int i = 0; i < m_WordToDisplay.Length; i++){
             m_WordToDisplay[i] = ('_');
         }

My guess method to pass in the letter chosen by the user:

     public void Guess (char letter){
         if (Outcome != Outcome.InProgress)
             Debug.Log ("Game is not in progress");
 
         if (m_GuessedAlready.Contains(letter)){
             print("You already guessed that letter, dummy");
             return;
         }
 
         m_GuessedAlready.Add(letter);
 
         if (!Word.Contains(letter)){
             print("There is no" + letter);
             m_IncorrectGuesses += 1;
 
             if (m_IncorrectGuesses > m_numberOfMistakesAllowed){
                 Outcome = Outcome.Loss;
                 print ("You lost");    
             }
             else{
                 print ("Number of guesses left: " + MistakesRemaining());
             }
 
         }
         else{
             FillInCorrectGuess(letter);
             Debug.Log (m_WordToDisplay);  // THIS HERE DOESNT PRINT THE WORD WITH THE GUESSED LETTERS BUT INSTEAD System.Char[]
         }

and finally, here is my method where i fill in every letter in the word with the guessed letter when its a letter that is part of the word

     private void FillInCorrectGuess (char letter){
         for (int i = 0; i < Word.Length; i++){
             if (Word[i] == letter)
                 m_WordToDisplay[i] = letter;
             
         }

So yeah, all i want to do ideally would be something like
Debug.Log ("Good guess! " + m_WordToDisplay); But doing so prints "Good guess! System.Char[]"

Thanks in advance anyone
