如何在每次按下按钮时改变其颜色？

Question

为了确保玩家知道他们选择继续前进到我的游戏上的难度，我希望通过按钮的前景色清楚地表明当前的难度。 到目前为止，这是我的代码，只要按下每个按钮，它们就会改变其前景色：

public Form1()
    {
        InitializeComponent();
        MinimizeBox = false;
        MaximizeBox = false;

    }

    bool diffchosen = false;
    public static string difficulty;
    public static double multiplier;
    public static int lives;

    private void Form1_Load(object sender, EventArgs e)
    {

    }

    private void easyButton_Click(object sender, EventArgs e)
    {
        this.ForeColor = Color.White;


        diffchosen = true;
        difficulty = "Easy";
        multiplier = 0.8;
        lives = 4;

    }

    private void mediumButton_Click(object sender, EventArgs e)
    {
        this.ForeColor = Color.White;


        diffchosen = true;
        difficulty = "Medium";
        multiplier = 1.0;
        lives = 3;


    }

    private void hardButton_Click(object sender, EventArgs e)
    {
        this.ForeColor = Color.White;

        diffchosen = true;
        difficulty = "Hard";
        multiplier = 1.5;
        lives = 2;


    }

    private void playButton_Click(object sender, EventArgs e)
    {
        if (diffchosen == false)
        {
            MessageBox.Show("Please choose a difficulty before proceeding");
        }
        else
        {
            Game_Screen game_Screen = new Game_Screen();

            this.Hide();
            game_Screen.Show();
        }
    }

但是我很难确保当玩家决定选择另一个选项时，其他两个选项具有黑色前景色属性。 我事先使用过此方法，但是它带来了这样的问题，例如，每当我按下按钮时，中按钮和硬按钮都会决定将其前景色更改为白色：

if (difficulty == "Hard" || difficulty = "Medium")
{
   this.ForeColour = Color.Black;       
}

如何创建一个循环，该循环将根据用户对按钮的选择来更改每个按钮的前景色？

Answer 1

最简单的方法可能只是创建一个切换功能，例如

private void ToggleButton(int button)
{
    easyButton.ForeColor = Color.Black;
    mediumButton.ForeColor = Color.Black;
    hardButton.ForeColor = Color.Black;

    switch (button)
    {
        case 1: easyButton.ForeColor = Color.White; break;
        case 2: mediumButton.ForeColor = Color.White; break;
        case 3: hardButton.ForeColor = Color.White; break;
    }
}

然后在每次点击事件中，您只需使用相应的“按钮号”调用此函数

例如

private void easyButton_Click(object sender, EventArgs e)
{
    ToggleButton(1);
    ...
}

private void mediumButton_Click(object sender, EventArgs e)
{
    ToggleButton(2);
    ...
}

private void hardButton_Click(object sender, EventArgs e)
{
    ToggleButton(3);
    ...
}
