在Winforms中更改表单上单选按钮的文本颜色

我正在将C＃用于Winforms应用程序，但似乎无法更改3组单选按钮上的默认/“未选中”颜色。我知道有一种方法不必单独按每个按钮。在该部分foreach清除选中状态优良工程。这是我尝试过的。

 public void ClearForm()
        {
            foreach (RadioButton radio1 in carbonationGroupBox.Controls.OfType<RadioButton>().ToList())

                if (radio1.Checked == true)
                {
                    radio1.ForeColor = Color.Black;
                    radio1.Checked = false;
                }

            foreach (RadioButton radio2 in strengthGroupBox.Controls.OfType<RadioButton>().ToList())

                if (radio2.Checked == true)
                {
                    radio2.ForeColor = Color.Black;
                    radio2.Checked = false;
                }

            foreach (RadioButton radio3 in sweetnessGroupBox.Controls.OfType<RadioButton>().ToList())

                if (radio3.Checked == true)
                {
                    radio3.ForeColor = Color.Black;
                    radio3.Checked = false;
                }

这是一个其中一个更改颜色的分组框中的三个单选按钮的代码。

private void topStrengthHydromel_CheckedChanged(object sender, EventArgs e)
{
    topStrengthStandard.ForeColor = Color.Black;
    topStrengthSack.ForeColor = Color.Black;
    topStrengthHydromel.ForeColor = Color.Lime;
    strengthRadionButton = "Hydromel";
}

private void topStrengthStandard_CheckedChanged(object sender, EventArgs e)
{
    topStrengthHydromel.ForeColor = Color.Black;
    topStrengthSack.ForeColor = Color.Black;
    topStrengthStandard.ForeColor = Color.Lime;
    strengthRadionButton = "Standard";
}

private void topStrengthSack_CheckedChanged(object sender, EventArgs e)
{
    topStrengthHydromel.ForeColor = Color.Black;
    topStrengthStandard.ForeColor = Color.Black;
    topStrengthSack.ForeColor = Color.Lime;
    strengthRadionButton = "Sack";
}

我发现的问题是foreach该区域内的事件顺序。

这个命令：

            if (radio1.Checked == true)
            {
                radio1.ForeColor = Color.Black;
                radio1.Checked = false;
            }

触发了_CheckChanged事件并将颜色重新设置为Lime。

private void topStrengthHydromel_CheckedChanged(object sender, EventArgs e)
{
    topStrengthStandard.ForeColor = Color.Black;
    topStrengthSack.ForeColor = Color.Black;
    topStrengthHydromel.ForeColor = Color.Lime;
    strengthRadioButton = "Hydromel";
}

切换顺序，以便在radio1.Checked = false发生错误之前radio1.ForeColor = Color.Black;就发生了！
