簡單的Qt閱讀從文本文件未編譯

計劃基本上我做了一個簡單的程序來閱讀文本行，但每當我運行該程序，我得到的簡單的Qt閱讀從文本文件未編譯

no match for 'operator>>' (operand types are 'QFile' and 'QString') 
while(file >> name >> month >> day >> year >> subject >> level >> apages >> total >> one >> two >> three >> four >> five >> six >> seven >> eight >> nine >> ten)

錯誤和其他錯誤：

expected unqualified-id before '<<' token 
     QDebug << QString(name);

我一直在試圖找到一個小時在線的東西，但我真的找不到任何有用或我能理解的東西。我真的很感激任何可以提供的輸入。

相關代碼：

#include "mainwindow.h" 
#include "ui_mainwindow.h" 
#include <QtCore/QCoreApplication> 
#include <QtCore> 
#include <QFile> 
# 
#include <QDebug> 

MainWindow::MainWindow(QWidget *parent) : 
    QMainWindow(parent), 
    ui(new Ui::MainWindow) 
{ 
    ui->setupUi(this); 
} 

MainWindow::~MainWindow() 
{ 
    delete ui; 
} 

void MainWindow::on_pushButton_clicked() 
{ 
    QString name, month, subject, level; 
    int day, year, apages, total, one, two, three, four, five, six, seven, eight, nine, ten; 

    QFile file("C:/Users/brandan/Desktop/GUIPrograms/Kumon.txt"); 
    if (!file.open(QIODevice::ReadOnly | QIODevice::Text)) 
     return; 

    while(file >> name >> month >> day >> year >> subject >> level >> apages >> total >> one >> two >> three >> four >> five >> six >> seven >> eight >> nine >> ten) 
    { 
     QDebug << name << month << day << year << subject << level << apages << total << one << two << three << four << five << six << seven << eight << nine << ten; 
    } 

}
