C++11新特性之tie、tuple的應用

//tuple
std::tuple<int, int, int, int, QString> Thorface::getUserInfoToJudgeOpendoor(QString strUserCode)
{
int iunpaidOrderList = 0;
int iunhandledOrderList = 0;
int istatus = 0;
int ibindFace = 0;
QString strUserName = "";
    return std::make_tuple(iunpaidOrderList, iunhandledOrderList, istatus, ibindFace, strUserName);
}

//tie解析
                int iunpaidOrderList = 0;
                int iunhandledOrderList = 0;
                int istatus = -1;
                int ibindFace = -1;
                QString strUserName = "";
                std::tie(iunpaidOrderList, iunhandledOrderList, istatus, ibindFace, strUserName) = getUserInfoToJudgeOpendoor(strName);

tuple是一個固定大小的不同類型值的集合，是泛化的std::pair。和c#中的tuple類似，但是比c#中的tuple強大得多。我們也可以把他當做一個通用的結構體來用，不需要創建結構體又獲取結構體的特征，在某些情況下可以取代結構體使程序更簡潔，直觀。
