反向查找

    int nFontSize = 0;    std::map<int, int>::iterator itBegin = m_mapFontSize.begin();    std::map<int, int>::iterator itEnd = m_mapFontSize.end();    while (itBegin != itEnd)    {        if (itBegin->second == m_pTabelFont->lfHeight)        {            nFontSize = itBegin->first;            break;        }        itBegin++;    }
