如何在wpf c#中实现checkbox的反选

<CheckBox Content="Select All" Checked="CheckBox_Checked" Unchecked="CheckBox_Unchecked"/>

private void CheckBox_Checked(object sender, RoutedEventArgs e)
{
    // 获取全选Checkbox的状态
    bool isChecked = (sender as CheckBox).IsChecked ?? false;

    // 遍历需要反选的Checkbox控件
    foreach (var checkBox in FindVisualChildren<CheckBox>(this))
    {
        // 设置Checkbox的IsChecked属性为与全选Checkbox相反的值
        checkBox.IsChecked = !isChecked;
    }
}

private void CheckBox_Unchecked(object sender, RoutedEventArgs e)
{
    // 获取全选Checkbox的状态
    bool isChecked = (sender as CheckBox).IsChecked ?? false;

    // 遍历需要反选的Checkbox控件
    foreach (var checkBox in FindVisualChildren<CheckBox>(this))
    {
        // 设置Checkbox的IsChecked属性为与全选Checkbox相反的值
        checkBox.IsChecked = !isChecked;
    }
}

// 辅助方法，用于遍历可视化树查找指定类型的控件
private static IEnumerable<T> FindVisualChildren<T>(DependencyObject dependencyObject) where T : DependencyObject
{
    if (dependencyObject != null)
    {
        for (int i = 0; i < VisualTreeHelper.GetChildrenCount(dependencyObject); i++)
        {
            DependencyObject child = VisualTreeHelper.GetChild(dependencyObject, i);
            if (child != null && child is T)
            {
                yield return (T)child;
            }

            foreach (T childOfChild in FindVisualChildren<T>(child))
            {
                yield return childOfChild;
            }
        }
    }
}
