西安交通大学c#五子棋

以下是西安交通大学C#五子棋的实现方法：

1. 创建一个棋盘类，包含棋盘大小、棋子颜色等属性和方法。

public class Chessboard
{
    private int size; // 棋盘大小
    private int[,] board; // 棋盘数组，0表示空，1表示黑子，2表示白子

    public Chessboard(int size)
    {
        this.size = size;
        board = new int[size, size];
    }

    public bool PutChess(int x, int y, int color)
    {
        if (x < 0 || x >= size || y < 0 || y >= size || board[x, y] != 0)
        {
            return false;
        }
        board[x, y] = color;
        return true;
    }

    public int CheckWin(int x, int y)
    {
        int color = board[x, y];
        int count = 1;
        int i, j;

        // 横向
        for (i = x - 1; i >= 0 && board[i, y] == color; i--)
        {
            count++;
        }
        for (i = x + 1; i < size && board[i, y] == color; i++)
        {
            count++;
        }
        if (count >= 5)
        {
            return color;
        }

        // 纵向
        count = 1;
        for (j = y - 1; j >= 0 && board[x, j] == color; j--)
        {
            count++;
        }
        for (j = y + 1; j < size && board[x, j] == color; j++)
        {
            count++;
        }
        if (count >= 5)
        {
            return color;
        }

        // 左上到右下
        count = 1;
        for (i = x - 1, j = y - 1; i >= 0 && j >= 0 && board[i, j] == color; i--, j--)
        {
            count++;
        }
        for (i = x + 1, j = y + 1; i < size && j < size && board[i, j] == color; i++, j++)
        {
            count++;
        }
        if (count >= 5)
        {
            return color;
        }

        // 右上到左下
        count = 1;
        for (i = x + 1, j = y - 1; i < size && j >= 0 && board[i, j] == color; i++, j--)
        {
            count++;
        }
        for (i = x - 1, j = y + 1; i >= 0 && j < size && board[i, j] == color; i--, j++)
        {
            count++;
        }
        if (count >= 5)
        {
            return color;
        }

        return 0;
    }
}

2. 创建一个游戏类，包含游戏状态、当前玩家、棋盘等属性和方法。

public class Game
{
    private Chessboard chessboard;
    private int currentPlayer;
    private bool isPlaying;

    public Game(int size)
    {
        chessboard = new Chessboard(size);
        currentPlayer = 1;
        isPlaying = true;
    }

    public bool PutChess(int x, int y)
    {
        if (!isPlaying)
        {
            return false;
        }
        if (chessboard.PutChess(x, y, currentPlayer))
        {
            int winner = chessboard.CheckWin(x, y);
            if (winner != 0)
            {
                Console.WriteLine("Player {0} wins!", winner);
                isPlaying = false;
            }
            else
            {
                currentPlayer = 3 - currentPlayer;
            }
            return true;
        }
        return false;
    }
}

3. 在主函数中创建游戏对象，并循环读取玩家输入并下棋。

static void Main(string[] args)
{
    Game game = new Game(15);
    while (game.IsPlaying)
    {
        Console.WriteLine("Player {0}'s turn:", game.CurrentPlayer);
        Console.Write("x = ");
        int x = int.Parse(Console.ReadLine());
        Console.Write("y = ");
        int y = int.Parse(Console.ReadLine());
        if (!game.PutChess(x, y))
        {
            Console.WriteLine("Invalid input!");
        }
    }
}
