推荐答案

这可能已经在另一篇文章中回答了，听起来是一样的:

This might have been answered in another post, it sounds the same:

将具有不同父级的 Windows 窗体单选按钮分组C#中的控件

这是公认的解决方案:

恐怕你必须手动处理这个……还不错实际上，您可以将所有 RadioButton 存储在列表中，并为所有这些事件使用一个事件处理程序:

I'm afraid you'll have to handle this manually... It's not so bad actually, you can probably just store all the RadioButton in a list, and use a single event handler for all of them:

private List<RadioButton> _radioButtonGroup = new List<RadioButton>();
private void radioButton_CheckedChanged(object sender, EventArgs e)
{
    RadioButton rb = (RadioButton)sender;
    if (rb.Checked)
    {
        foreach(RadioButton other in _radioButtonGroup)
        {
            if (other == rb)
            {
                continue;
            }
            other.Checked = false;
        }
    }
}

这是另一个提出同样问题的问题:不同面板中的单选按钮作为一个组

Here's another question asking the same thing: Radiobuttons as a group in different panels
