Question

我是C＃语言的新手，很抱歉，如果这是一个容易解决的问题，我已经检查了网站，目前遇到的问题是变量已更改，但方法未引起任何变化，这听起来很模糊，所以下面是一些代码。

public string PlayerToIcon(int LocA, int LocB)
{
    PlayGame play = new PlayGame();
    int[,] Board = play.Board;
    int LocData = (Board[LocA, LocB]);
    if (LocData == 0) { return " "; }
    else if (LocData == 1) { return "X"; }
    else { return "O"; }
}

木板如下所示，基本上是一个简单的阵列。 -这在另一个文件中

public class PlayGame
{
    public int[,] Board = new int[3, 3]
    {          //A B C
                {0,0,0 }, // 1
                {0,0,0 }, // 2
                {0,0,0 }  // 3
    };
}

我制作了一个函数来更改数组中的数字，并且在使用直接命令时可以显示该数字，但是在PlayerToIcon中看不到数字发生了变化。例如，如果它是0，而我将其更改为1，PlayerToIcon仍将其读取为0

谢谢抱歉，这是一个简单的问题

这就是更改数组中变量的原因，“返回状态”确保无论是1还是2都不会更改

public class PlayGame
{
    public bool SelectSquare(string Location, int Player)
    {
        List<int> ConvertedLocation = ConvertLoc(Location);
        Console.WriteLine(ReturnState(Location));
        Console.WriteLine(ConvertedLocation[0].ToString() + ConvertedLocation[1].ToString());
        if (ReturnState(Location) == 0) { Board[ConvertedLocation[0], ConvertedLocation[1]] = Player; return true;}
        else { return false; }
    }
 }

在显示器上无法识别代码

public class Interface
{
    PlayGame play = new PlayGame();
    public void GenMap()
    {
        string NewLine;
        Console.Clear();
        Console.WriteLine("    | A | B | C |");
        Console.WriteLine("-----------------");
        new PlayGame();
        NewLine = System.String.Format("| 1 | {0} | {1} | {2} |", (play.PlayerToIcon(play,0, 0)), (play.PlayerToIcon(play, 0, 1)), (play.PlayerToIcon(play, 0, 2)));
        Console.WriteLine((string)NewLine);
        Console.WriteLine("----------------");
        NewLine = System.String.Format("| 2 | {0} | {1} | {2} |", (play.PlayerToIcon(play, 1, 0)), (play.PlayerToIcon(play, 1, 1)), (play.PlayerToIcon(play, 1, 2)));
        Console.WriteLine((string)NewLine);
        Console.WriteLine("-----------------");
        NewLine = System.String.Format("| 3 | {0} | {1} | {2} |", (play.PlayerToIcon(play, 2, 0)), (play.PlayerToIcon(play, 2, 1)), (play.PlayerToIcon(play, 2, 2)));
        Console.WriteLine((string)NewLine);
        Console.WriteLine("-----------------");
    }
    public string PlayerToIcon(int LocA, int LocB)
    {
        int[,] Board = play.Board;
        int LocData = (Board[LocA, LocB]);
        if (LocData == 0) { return " "; }
        else if (LocData == 1) { return "X"; }
        else { return "O"; }
    }

}

Answer 1

public string PlayerToIcon(int LocA, int LocB)
{
    PlayGame play = new PlayGame(); // creates a new PlayGame
    int[,] Board = play.Board;
    int LocData = (Board[LocA, LocB]);
    if (LocData == 0) { return " "; }
    else if (LocData == 1) { return "X"; }
    else { return "O"; }
}

应更改为以下内容：

// added as param ---------vvvvvvvvvvvvv
public string PlayerToIcon(PlayGame play, int LocA, int LocB)
{
    int[,] Board = play.Board;
    int LocData = (Board[LocA, LocB]);
    if (LocData == 0) { return " "; }
    else if (LocData == 1) { return "X"; }
    else { return "O"; }
}

然后这样称呼：

var icon = PlayerToIcon(myPlayer, 1, 1);

您甚至可以将其作为函数添加到您的PlayGame类中：

public class PlayGame
{
    public int[,] Board = new int[3, 3]
    {          //A B C
                {0,0,0 }, // 1
                {0,0,0 }, // 2
                {0,0,0 }  // 3
    };

    public string PlayerToIcon(int LocA, int LocB)
    {
        //PlayGame play = new PlayGame();
        //int[,] Board = play.Board;
        int LocData = (Board[LocA, LocB]);
        if (LocData == 0) { return " "; }
        else if (LocData == 1) { return "X"; }
        else { return "O"; }
    }
}

然后以这种方式调用它：

var icon = myPlayer.PlayerToIcon(1, 1);

根据您编辑的问题：

public class Interface
{
    PlayGame play = new PlayGame();
    public void GenMap()
    {
        string NewLine;
        Console.Clear();
        Console.WriteLine("    | A | B | C |");
        Console.WriteLine("-----------------");
        //new PlayGame(); (WHY??)
        for(int i=0;i<3;i++)
        {
            NewLine = System.String.Format("| {0} | {1} | {2} | {3} |",
                i+1, 
                /*play.*/PlayerToIcon(/*play, */i, 0), 
                /*play.*/PlayerToIcon(/*play, */i, 1), 
                /*play.*/PlayerToIcon(/*play, */i, 2));
            Console.WriteLine(NewLine);
            Console.WriteLine("-----------------");
        }
    }
    public string PlayerToIcon(int LocA, int LocB)
    {
        int[,] Board = play.Board;
        int LocData = (Board[LocA, LocB]);
        if (LocData == 0) { return " "; }
        else if (LocData == 1) { return "X"; }
        else { return "O"; }
    }
}

这是我开始时得到的输出：

    | A | B | C |
-----------------
| 1 |   |   |   |
-----------------
| 2 |   |   |   |
-----------------
| 3 |   |   |   |
-----------------

Answer 2

在调用PlayerToIcon之前，将您的PlayGame变量设置为变量，然后将其传递给他，如下所示：

public string PlayerToIcon(PlayGame myGame, int LocA, int LocB)
{
    int[,] Board = myGame.Board;
    int LocData = (Board[LocA, LocB]);
    if (LocData == 0) { return " "; }
    else if (LocData == 1) { return "X"; }
    else { return "O"; }
}

您必须这样做：

new PlayGame();

仅当您要将板重置为“启动”时，才需要花费很多时间。

澄清这样的事情：

PlayGame myGame = new PlayGame(); 
PlayerToIcon(myGame, 1, 1);
PlayerToIcon(myGame, 1, 2);
PlayerToIcon(myGame, 0, 1);
[...]

Answer 3

class Program
{
    static void Main()
    {
        string playerToIcon = new PlayGame().PlayerToIcon(new PlayGame(), 0, 1); 

    }

}
public class PlayGame
{
    public int[,] Board = new int[3, 3]
    {          //A  B C
            {0,0,0 }, // 1
            {0,0,0 }, // 2
            {0,0,0 }  // 3
    };
    public string PlayerToIcon(PlayGame play, int LocA, int LocB)
    {
        int[,] Board = play.Board;
        int LocData = (Board[LocA, LocB]);
        if (LocData == 0)
        {
            return "";
        }
        else if (LocData == 1)
        {
            return "X";
        }
        else
        {
            return "0";
        }

    }
}

变量未在函数C＃中更新
