c# - C# 使用接口查找 Connect 4 的获胜者

Question

我目前正在执行一项使用 Visual Studio 表单在标准 7x6 网格上创建 Connect 4 游戏的任务。我已经在这里搜索过，但找不到使用与我应该检查获胜相同的方法的问题。我已经完成了游戏的架构；板子功能齐全，棋子正确掉落，已经放置的棋子不能被覆盖。然而，任务的关键是检查获胜者需要实现一个接口。这是所需的接口：

interface Winner
{
    //find winner in the specified direction starting from (c,r)
    bool straightup(int c, int r);
    bool straightdown(int c, int r);
    bool left(int c, int r);
    bool right(int c, int r);
    bool diagleftup(int c, int r);
    bool diagrightdown(int c, int r);
    bool diagleftdown(int c, int r);
    bool diagrightup(int c, int r);

    //return true if there is winner
    bool winner();
}

如果需要，这是板的代码：

    bool isWinner, xTurn; //Keeps track if there is a winner and whose turn it is
    int xWins, oWins; //Keeps track of each players' wins
    //Keeps track of which row the next piece in the column will drop
    int col1Drop, col2Drop, col3Drop, col4Drop, col5Drop, col6Drop, col7Drop; 
    Button[,] places; //Array of buttons on the board

    public Form1()
    {
        InitializeComponent();
        isWinner = false;
        xTurn = true;
        xWins = 0;
        oWins = 0;
        col1Drop = 0; col2Drop = 0; col3Drop = 0; col4Drop = 0; col5Drop = 0; col6Drop = 0; col7Drop = 0;
        currentTurn.Text = "X";
        winRecords.Text = "Record:" + Environment.NewLine + Environment.NewLine + "X Wins - 0"+ Environment.NewLine + "O Wins - 0";
        //Initializes the array of buttons on the board, starting from left to right, bottom to top
        places = new Button[,]{ { col1row1, col1row2, col1row3, col1row4, col1row5, col1row6 }, { col2row1, col2row2, col2row3, col2row4, col2row5, col2row6 }, { col3row1, col3row2, col3row3, col3row4, col3row5, col3row6 }, { col4row1, col4row2, col4row3, col4row4, col4row5, col4row6 }, { col5row1, col5row2, col5row3, col5row4, col5row5, col5row6 }, { col6row1, col6row2, col6row3, col6row4, col6row5, col6row6 }, { col7row1, col7row2, col7row3, col7row4, col7row5, col7row6 } };
    }

    private void col1row6_Click(object sender, EventArgs e) //Runs when top button on column is clicked, all other buttons in column are disabled
    {
        if(xTurn) //Plays if its X's turn
        {
            if (col1Drop < 6) //Places piece as long as there's still a spot available 
            {
                places[0, col1Drop].BackgroundImage = GUI_Connect4.Properties.Resources.X;
                places[0, col1Drop].BackgroundImageLayout = ImageLayout.Stretch; //Fills the next available row in the column
                xTurn = false; //Changes it to next player's turn
                currentTurn.Text = "O";
                col1Drop++; //Moves to next avaiable column
            }
        }
        else //Plays if it's O's turn
        {
            if (col1Drop < 6)
            {
                places[0, col1Drop].BackgroundImage = GUI_Connect4.Properties.Resources.O;
                places[0, col1Drop].BackgroundImageLayout = ImageLayout.Stretch;
                xTurn = true;
                currentTurn.Text = "X";
                col1Drop++;
            }
        }
    } //This code is the same for each column, with values changed accordingly

我将如何检查是否获胜，接口应该在哪里实现？我假设它应该只在一个单独的 checkWinner 方法中实现，该方法在播放一段时运行。
