前台xaml：

<Grid>
        <StackPanel>
            <RadioButton x:Name="rbA" Content="选项A" GroupName="group1"></RadioButton>
            <RadioButton x:Name="rbB" Content="选项B" GroupName="group1"></RadioButton>
        </StackPanel>
    </Grid>

后台： 放在构造函数中。

 rbA.Checked += new RoutedEventHandler(radio_Checked);
            rbB.Checked += new RoutedEventHandler(radio_Checked);
            rbA.Unchecked += new RoutedEventHandler(radio_Unchecked);
            rbB.Unchecked += new RoutedEventHandler(radio_Unchecked);

 void radio_Unchecked(object sender, RoutedEventArgs e)
        {
            RadioButton btn = sender as RadioButton;
            if (btn == null)
                return;
            if (btn.Name == "rbA")
            {

            }
            if (btn.Name == "rbB")
            {

            }
        }

        void radio_Checked(object sender, RoutedEventArgs e)
        {
           // 同UnChecked判断。
        }
