使用属性将单选按钮的值传递给另一个窗体

public string SelectedValue { get; set; }

private void radioButton_CheckedChanged(object sender, EventArgs e)
{
    RadioButton radioButton = (RadioButton)sender;
    if (radioButton.Checked)
    {
        SelectedValue = radioButton.Text;
    }
}

public class SecondForm : Form
{
    private FirstForm firstForm;

    public SecondForm(FirstForm firstForm)
    {
        this.firstForm = firstForm;
    }

    private void button_Click(object sender, EventArgs e)
    {
        string selectedValue = firstForm.SelectedValue;
        // 使用选中的值进行后续操作
    }
}
