根据点击的按钮更改按钮内容

Question

我正在为一项作业开展一个tic tac toe游戏，而我想要制作游戏的方式似乎不太可能。我认为其他人已经提出了这个问题，但我在网上任何答案中看到的所有代码都比我想做的更先进（或者看起来那样）。

目前，我对所有9个按钮使用了1次点击事件。当玩家1玩游戏时，它将成为玩家2的回合。

因为我对所有按钮使用相同的点击事件，所以我无法弄清楚如何使每个按钮的内容变为“X”或“O”，具体取决于轮到谁。

如果我正在做9个不同的点击事件，我知道该怎么做，但这个任务的重点是使用简单的方法，这让我发疯。

我最初的感觉是应该有一个“this.Content =”X“;”选项等等。

这是我到目前为止的代码（减去一些已经有效的方法。我想要工作的代码行周围有星号，但不知道如何让它们工作。）：

public partial class MainWindow : Window
{
    bool turn;
    string playerX;
    string playerO;

    public MainWindow()
    {
        InitializeComponent();
    }

    private void IsTurn ()
    {
        if (turn==true)
        {
            textBlockGameInfo.Text = "It is " + playerO + "'s turn";
            **button_Click.Content = "O";**
            turn = false;
        }
        else if (turn==false)
        {
            textBlockGameInfo.Text = "It is " + playerX + "'s turn";
            **button_Click.Content = "X";**
            turn = true;
        }
    }

    private void button_Click(object sender, RoutedEventArgs e)
    {
        IsTurn();
    }
}

}

Answer 1

您正在寻找的是Button.Text属性。

当玩家1点击按钮时，你会想要

button.Text = "O";

当玩家2点击按钮时：

button.Text = "X";

Answer 2

您绝对应该将方法中收到的发件人强制转换为Button。 button_Click方法中的发件人将是玩家实际点击的按钮。

一旦按下按钮，您就可以根据转弯设置其内容。你的转弯方法可以返回要分配的角色。有点像这样的东西会起作用：

var button = sender as Button;
if (button == null) return;

button.Content = IsTurn();

Answer 3

尝试遵循@KOTIX的建议，让我的游戏运转起来，但我仍然对按钮状况如何发挥作用感到困惑。我想我只需要回去看看一些事情。

这是我对整个tic tac toe游戏的最终代码。查看最后两种方法，了解button_click的处理和使用方式。

我也认为必须有一个更好的方法来处理胜利者，但这又是另一个问题的另一个问题:)

希望这可以帮助其他人。
