可以使用Qt提供的QAxObject库来读取Excel文件。以下是一个简单的示例代码:
```
#include <QApplication>
#include <QAxObject>
#include <QDebug>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QAxObject excel("Excel.Application"); // 创建Excel应用对象
QAxObject *workbooks = excel.querySubObject("Workbooks"); // 获取工作簿集合
QAxObject *workbook = workbooks->querySubObject("Open(const QString&)", "test.xlsx"); // 打开Excel文件
QAxObject *worksheet = workbook->querySubObject("Worksheets(int)", 1); // 获取第一个工作表
// 读取单元格A1的值
QAxObject *cell = worksheet->querySubObject("Cells(int, int)", 1, 1);
QVariant value = cell->property("Value");
qDebug() << "A1:" << value.toString();
// 读取表格范围A1:B2的值
QAxObject *range = worksheet->querySubObject("Range(const QString&)", "A1:B2");
QVariant table = range->property("Value");
QVariantList rows = table.toList();
for (int i = 0; i < rows.size(); i++) {
QVariantList cols = rows.at(i).toList();
for (int j = 0; j < cols.size(); j++) {
qDebug() << i << j << cols.at(j).toString();
}
}
// 释放资源
cell->dynamicCall("Delete()");
range->dynamicCall("Delete()");
workbook->dynamicCall("Close()");
excel.dynamicCall("Quit()");
delete cell;
delete range;
delete worksheet;
delete workbook;
delete workbooks;
return a.exec();
}
```
需要注意的是,如果要在Qt中使用QAxObject库,需要在.pro文件中添加`QT += axcontainer`。另外,需要确保电脑中已经安装了Microsoft Office软件,否则可能会出现错误。
