How to get all checked checkboxes in WPF?

I tried to find any solutions for this problem but I did not succeed. I only found solutions for WinForms which do not work for WPF.

I have a simple form that has some checkboxes on it. I want to know what checkboxes are checked. The only way I know to do it is to create a method for each checkbox like

"Checkbox1_Checked(object sender, RoutedEventArgs e)" 

and add the name of a checkbox in a List (and remove it from list if the box is unchecked).

Is there any other way I can get all the checked checkboxes? Something like

foreach (var cb in this.Controls)
{
    if (cb is Checkbox && cb.IsCheked()) // blablabla
}
