QT打开一个路径下的所有的.xls文件，并使用qdebug打印出打开的所有的文件的名字判断文件里面是否含有字符串“shijain”，并将所在的位置信息显示在textbrowe

好的，我可以帮你解决这个问题。以下是代码实现：

#include <QDir>
#include <QFileInfoList>
#include <QTextStream>
#include <QMessageBox>

void MainWindow::openExcelFiles()
{
    QString folderPath = "your/folder/path"; // 文件夹路径
    QDir folder(folderPath);
    QFileInfoList fileList = folder.entryInfoList(QStringList() << "*.xls" << "*.xlsx", QDir::Files);
    // 获取文件夹下所有的xls和xlsx文件

    foreach (QFileInfo file, fileList) {
        if (file.isFile() && file.exists()) {
            QString filePath = file.absoluteFilePath(); // 文件的绝对路径
            QString fileName = file.fileName(); // 文件名

            if (containsStringInExcel(filePath, "shijian")) {
                // 文件中包含字符串"shijian"
                ui->textBrowser->append(fileName + ": " + filePath);
            }
        }
    }
}

bool MainWindow::containsStringInExcel(const QString &filePath, const QString &searchString)
{
    QAxObject excel("Excel.Application");
    QAxObject *workbooks = excel.querySubObject("Workbooks");
    QAxObject *workbook = workbooks->querySubObject("Open(const QString&)", filePath);
    QAxObject *worksheets = workbook->querySubObject("Worksheets");
    int sheetCount = worksheets->property("Count").toInt();

    for (int i = 1; i <= sheetCount; i++) {
        QAxObject *worksheet = worksheets->querySubObject("Item(int)", i);
        QAxObject *usedRange = worksheet->querySubObject("UsedRange");
        QAxObject *rows = usedRange->querySubObject("Rows");
        int rowCount = rows->property("Count").toInt();
        QAxObject *columns = usedRange->querySubObject("Columns");
        int columnCount = columns->property("Count").toInt();

        for (int row = 1; row <= rowCount; row++) {
            for (int column = 1; column <= columnCount; column++) {
                QAxObject *cell = worksheet->querySubObject("Cells(int,int)", row, column);
                QString cellText = cell->property("Value").toString();

                if (cellText.contains(searchString, Qt::CaseInsensitive)) {
                    // 单元格中包含searchString
                    workbook->dynamicCall("Close()");
                    excel.dynamicCall("Quit()");
                    return true;
                }
            }
        }

        worksheet->dynamicCall("Release()");
        usedRange->dynamicCall("Release()");
        rows->dynamicCall("Release()");
        columns->dynamicCall("Release()");
    }

    workbook->dynamicCall("Close()");
    excel.dynamicCall("Quit()");
    return false;
}

这段代码会遍历指定路径下所有的.xls和.xlsx文件，如果文件中包含字符串"shijian"，则将文件名和位置信息显示在textBrowser中。
