// ToXml creates an XML encoding of the permission and its current state; FromXml reconstructs a
// permission with the specified state from the XML encoding.
private static void ToFromXmlDemo()
{

    UIPermission uiPerm1 = new UIPermission(UIPermissionWindow.SafeTopLevelWindows);
    UIPermission uiPerm2 = new UIPermission(PermissionState.None);
    uiPerm2.FromXml(uiPerm1.ToXml());
    bool result = uiPerm2.Equals(uiPerm1);
    if (result)
    {
        Console.WriteLine("Result of ToFromXml = " + uiPerm2.ToString());
    }
    else
    {
        Console.WriteLine(uiPerm2.ToString());
        Console.WriteLine(uiPerm1.ToString());
