get-pdf-attachment-info.cpp

// Open document
auto doc = MakeObject<Document>(u"Document.pdf");

// Get particular embedded file

// Get the file properties
Console::WriteLine(u"Name: {0}", fileSpecification->get_Name());
Console::WriteLine(u"Description: {0}", fileSpecification->get_Description());
Console::WriteLine(u"Mime Type: {0}", fileSpecification->get_MIMEType());
