Answer 1

您可以使用私有变量来维护所选单选按钮的内容。将"已检查"事件添加到两个单选按钮，两个单选按钮的同一事件。

    private string radioContent = "";
    private void RadioButton_Checked(object sender, RoutedEventArgs e)
    {
        var radio = (sender as RadioButton);
        radioContent = radio.Content.ToString();
    }
and on the save button click,
  private void save_data(object sender, RoutedEventArgs e)
  {
   window2 win2 = new window2();
   MessageBox.Show(radioContent);// here when it displays " System.Windows.Controls.StackPanel "
  if (radioContent.Length <= 0)
    MessageBox.Show("Please select a type.");
  else
    win2.name.Text = radioContent.ToString();
  win2.Show();
  //this.Close();
   }
