}

        info("Check Catch block");
        throw Global::error("Written to the Infolog.");

    catch (Exception::Error)
    {
        ex = CLRInterop::getLastException();
        //ex.get_Message(); // Whole Message collection
        info(strFmt("Exception message %1",ex.ToString()));
 //infolog.text(infologLine());
