前言：项目中会用到.ini文件存储保存数据

一、写.ini文件

    QString path = "D:/lns/model.ini";
    QSettings* m_IniFile = new QSettings(path,QSettings::IniFormat);
    m_IniFile -> beginGroup("alarm");
    m_IniFile -> setValue("0",QString::number(examopen.worksheet));
    m_IniFile -> setValue("1",QString::number(examopen.SN_number));
    m_IniFile -> endGroup();
    delete m_IniFile;

二、读.ini文件

        QString path = "D:/lns/model.ini";
        QSettings *demo = new QSettings(path, QSettings::IniFormat);
        demo -> beginGroup("alarm");
        QStringList str = demo -> allKeys();
        QString key1 = str.at(0);
        QString value1 = demo -> value(key1).toString();
        examopen.worksheet = value1.toInt();
        QString key2 = str.at(1);
        QString value2 = demo -> value(key2).toString();
        examopen.SN_number = value2.toInt();
        demo -> endGroup();
