How to bypass all the same type of controls in WPF?

Question

WPF

Good afternoon!
Tell me how to bypass all the controls in the window?
on WinForms did the following:

public static class Access
{
public static void FindAll(Control control)
  {
    foreach (Control c in control.Controls)
    {
      foreach (svc.Level2 lev in listLevel2)
      {
        ...
      }
    }
  }
}

The call was made as follows (from an arbitrary form): What is it for: modules are loaded in the main program window, it is necessary to show or hide them depending on the user's access level.
Access.FindAll(this);
