cvs 文件如何解析?

QList<QStringList> RwCvs::readToList(const QString &path, const QString separator)
{
    QList<QStringList> set;
    QFile fs(path);
    if(fs.open(QFile::ReadOnly | QFile::Text)){
        QTextStream stream(&fs);

        //读取单行数据
        QString lines;
        while (stream.readLineInto(&lines)) {
            set.push_back(lines.split(separator,QString::KeepEmptyParts));
        }
    }

    return set;
}
