Question

我正在研究这个项目，现在意识到我从未真正使用过“启用”/“禁用”功能，现在我想禁用特定按钮，而其他按钮仍然可以运行！（希望重启按钮在游戏结束后仍然有效）

有人可以帮我吗？在此先感谢您的任何答复！

private void button_click(object sender, EventArgs e)
{
    Button b = (Button)sender;
    if (turn)
        b.Text = "X";
    else
        b.Text = "O";

    turn = !turn;
    b.Enabled = false;

    checkForWinner();
}

private void checkForWinner()
{
    bool there_is_a_winner = false;

    if ((A1.Text == A2.Text) && (A2.Text == A3.Text) && (!A1.Enabled))
        there_is_a_winner = true;
    else if ((B1.Text == B2.Text) && (B2.Text == B3.Text) && (!B1.Enabled))
        there_is_a_winner = true;
    else if ((C1.Text == C2.Text) && (C2.Text == C3.Text) && (!C1.Enabled))
        there_is_a_winner = true;

    if (there_is_a_winner)
    {
        disableButtons();

        String winner = "";
        if (turn)
            winner = "O";
        else
            winner = "X";

        MessageBox.Show(winner + "Wins!", "Yay!");

    }//end if
}// End Check For Winner

private void disableButtons()
{
    foreach (Control c in Controls)
    {
        if (c.GetType() == typeof(Button))
        {
            Button b = (Button)c;
            b.Enabled = false;
        }//end foreach
    }
}

Answer 1

尝试

 private void disableButtons()
    {
        for (int x = 0; x < Controls.GetLength(); x++)
            if (Controls[x] is Button)
                Controls[x].Enabled = false;
    }

Answer 2

你应该循环遍历所有按钮，然后禁用它们。

public static void disableButtons(Control parent)
{
    foreach (Control c in parent.Controls)
        if (c.GetType() == typeof(Button))
            c.Enabled = false;
        else
            disableButtons(c);
}

然后在您的代码中，您应该传递面板（或表单）contatinig您的目标按钮。例如，如果您的按钮位于panel1中，那么您应该使用disableButtons(panel1);

c＃禁用特定按钮
