要在MFC中读写XLSX文件,您需要使用一个第三方库来处理XLSX格式。建议使用OpenXML SDK。
以下是一个简单的示例,用于使用OpenXML SDK在MFC应用程序中读取XLSX文件:
```cpp
#include <afx.h>
#include <iostream>
// Include OpenXML SDK headers
#include <OpenXmlPkg.h>
#include <OpenXmlPart.h>
#include <OpenXmlReader.h>
#include <OpenXmlWriter.h>
using namespace std;
using namespace System::IO::Packaging;
void ReadXlsxFile(const CString& strFilePath)
{
// Open the XLSX package
Package^ pkg = Package::Open(strFilePath, FileMode::Open, FileAccess::Read);
// Get the workbook part from the package
Uri^ uriWorkbook = gcnew Uri("/xl/workbook.xml", UriKind::Relative);
PackagePart^ ppWorkbook = pkg->GetPart(uriWorkbook);
// Create an OpenXmlReader object to read the workbook part
OpenXmlReader^ oxr = gcnew OpenXmlReader(ppWorkbook);
// Read the workbook part
while (oxr->Read())
{
if (oxr->Element->Type == typeof(Spreadsheet::Workbook))
{
// Process the workbook element
Spreadsheet::Workbook^ workbook = (Spreadsheet::Workbook^)oxr->LoadCurrentElement();
cout << "Workbook: " << to_string(workbook->Sheets->Count) << " sheets" << endl;
}
}
// Close the reader and package
oxr->Close();
pkg->Close();
}
```
这个示例使用OpenXmlReader来读取XLSX文件,并从Workbook元素中获取工作表的数量。
要使用OpenXML SDK写入XLSX文件,您可以使用类似的方法来获取WorkbookPart,然后使用OpenXmlWriter来写入内容。
