    // Add the hit test result to the list that will be processed after the enumeration.
    hitResultsList.Add(result.VisualHit);

    return HitTestResultBehavior.Continue;
}

' Return the result of the hit test to the callback.
Public Function MyHitTestResult(ByVal result As HitTestResult) As HitTestResultBehavior
    ' Add the hit test result to the list that will be processed after the enumeration.
