今天用到陣列在控制檯做了一個五子棋遊戲，實現如下： static void Main(string[] args)
        {
            string[,] QP = new string[17, 17];                                             //定義二維陣列QP同時設定棋盤大小
            while (true)
            {                 Console.Clear();
                int left = 16;
                int top = 8;
                for (int i = 0; i < QP.GetLength(0); i++)
                {
                    for (int j = 0; j < QP.GetLength(1); j++)                             //為陣列QP每個元素賦初值   用“□”代替棋盤網格         
                    {
                        QP[i, j] = "□";
                    }
                }
                for (int i = 0; i < QP.GetLength(0); i++)
                {
                    for (int j = 0; j < QP.GetLength(1); j++)
                    {
                        Console.Write(QP[i, j]);                                          //遍歷陣列QP 並將其列印在窗體 使介面看起來像是網格狀
                    }
                    Console.WriteLine();
                }                 bool mark = true;
                bool Jmark = true;
                while (Jmark)
