要在C++中操作Excel,可以使用Qt提供的QAxObject类。首先,需要在Qt项目中添加ActiveQt模块:
```c++
QT += axcontainer
```
然后,在代码中,可以使用QAxObject类打开Excel文件并读取或写入数据:
```c++
QAxObject *excel = new QAxObject("Excel.Application", this);
QAxObject *workbooks = excel->querySubObject("Workbooks");
QAxObject *workbook = workbooks->querySubObject("Open(const QString&)", "file.xlsx");
QAxObject *worksheets = workbook->querySubObject("Worksheets");
QAxObject *worksheet = worksheets->querySubObject("Item(int)", 1);
// 读取数据
QAxObject *cell = worksheet->querySubObject("Cells(int,int)", 1, 1);
QString value = cell->property("Value").toString();
qDebug() << "Value: " << value;
// 写入数据
cell = worksheet->querySubObject("Cells(int,int)", 1, 2);
cell->setProperty("Value", "Hello, world!");
workbook->dynamicCall("Save()");
excel->dynamicCall("Quit()");
```
需要注意的是,QAxObject对象需要手动释放资源,否则可能会导致内存泄漏。
