我當前的打字游戲功能（下面提供的代碼）的目標是從 10（困難）、20（中等）或 30（簡單）開始倒計時，這取決于游戲開始后用戶的難度選擇。一旦倒計時達到零或用戶用完生命，游戲就結束了（這會停止倒計時）。游戲正常啟動，顯示用戶輸入的第一個單詞，并從 10 開始倒計時。我目前的問題是我無法弄清楚如何停止計時器從 0 倒計時。我嘗試使用 t .Change(Timeout.Infinite , Timeout.Infinite) 并檢查 timeLeft == 0 時沒有占上風。我真的覺得我想得太多了（或想得不夠），非常感謝一些幫助或朝著正確方向輕推！我的代碼如下：    class Program{    // List of words to be typed    public static string[] words = { "some", "side", "add", "another", "would", "book" ,"water", "came" ,"your" ,"big","both", "from", "learn", "been", "me" ,"school" ,"land", "took", "place",            "try", "line", "tell", "earth", "can", "do","children", "without", "my", "must", "take", "follow", "year", "is", "being", "different", "miss", "could", "on", "he", "open", "night", "were",            "line","said", "around", "an", "plant", "know", "set","been", "life","young","of", "face", "we", "hand", "while", "is", "white", "call", "live","may", "study","after" ,"down", "him", "now", "different",            "could", "over", "work","all", "mean","begin","go","fall", "really", "oil", "before","into","one","name","has","a", "well", "got","something","turn" };    // Keeps track of words array    public static int numWords = 88;    public static int correctWords = 0;    // Initialize our random number generator    public static Random rand = new Random();    // Handles user input    public static string userInput = "";    public static string endGameChoice = "";    // Handles gamestate variables    public static bool gameActive = false;    public static int numLives = 0;    public static int timeLeft;    public static System.Threading.Timer t;    // Entry Point    static void Main(string[] args)    {        // Start the game        Start();    }
