使用 C++ 检查工作簿是否包含隐藏的外部链接

可能的使用场景

有时工作簿中包含隐藏的外部链接，无法在Microsoft Excel中查看。Aspose.Cells 会检索所有外部链接，无论它们是否可见。然而，你可以检查 ExternalLink.IsVisible 属性以确认外部链接是否可见。

检查工作簿是否包含隐藏的外部链接

以下示例加载包含隐藏外部链接的 源Excel文件。这些链接在Microsoft Excel中不可见，但在工作簿中存在。打印 ExternalLink.GetDataSource() 和 ExternalLink.IsReferred，之后会输出 ExternalLink.IsVisible 属性。在控制台输出中，你可以看到所有外部链接都不可见。

示例代码

#include <iostream>
#include "Aspose.Cells.h"

using namespace Aspose::Cells;

int main()
{
    Aspose::Cells::Startup();

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Loads the workbook which contains hidden external links
    Workbook workbook(srcDir + u"sample.xlsx");

    // Access the external link collection of the workbook
    ExternalLinkCollection links = workbook.GetWorksheets().GetExternalLinks();

    // Print all the external links and check their IsVisible property
    for (int i = 0; i < links.GetCount(); i++)
    {
        ExternalLink link = links.Get(i);
        std::cout << "Data Source: " << link.GetDataSource().ToUtf8() << std::endl;
        std::cout << "Is Visible: " << (link.IsVisible() ? "true" : "false") << std::endl;
        std::cout << std::endl;
    }

    Aspose::Cells::Cleanup();
}
