从文本文件程序读取的简单Qt无法编译

基本上，我做了一个简单的程序来读取一行文本，但是每当我运行该程序时，都会出现以下错误：

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)

和另一个错误：

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

我已经尝试了一个小时的在线内容，但是我真的找不到任何有效的或我能理解的东西。我将不胜感激，可以提供任何意见。

相关代码：

#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;
    }

}
