Radio buttons are used when you want the user to choose, usually, one or more items from a series of options, so by the end, you will have at least one selected item. If you want to provide the user to uncheck, then, you should really be using a Checkbox in the first place.
当您希望用户从一系列选项中选择一个或多个项目时，通常会使用单选按钮，因此到最后，您将至少选择一个项目。如果您想让用户取消选中，那么您首先应该真正使用 Checkbox。
At most in your case, you could provide some functionality such as a button to resetthe radio buttons, by doing something like rdBtn.Checked = false;
在您的情况下，您最多可以提供一些功能，例如通过执行以下操作来重置单选按钮的按钮rdBtn.Checked = false;

This might work:
这可能有效：
private void radio_click(object sender, EventArgs e)
{
if (radio.Checked)
{
radio.Checked = false;
}
}

Use the following code to use radio button like check box.
使用以下代码使用单选按钮，如复选框。
bool isChecked =false;
private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
isChecked = radioButton1.Checked;
}
private void radioButton1_Click(object sender, EventArgs e)
{
if (radioButton1.Checked && !isChecked)
radioButton1.Checked = false;
else
{
radioButton1.Checked = true;
isChecked = false;
}
}
