their names (using an indexer) and via a set of typed properties that return values of appropriate types. The names of the properties are case-insensitive. The properties in the collection are sorted alphabetically by name. ## Examples Shows how to work with built-in document properties. ```cpp auto doc = System::MakeObject(System::String(get_MyDir() + u"Properties.docx")); // The "Document" object contains some of its metadata in its members. std::cout << System::String::Format(u"Document filename:\n\t \"{0}\"", doc->get_OriginalFileName()) << std::endl; // The document also stores metadata in its built-in properties. // Each built-in property is a member of the document's "BuiltInDocumentProperties" object. std::cout << "Built-in Properties:" << std::endl; for (auto&& docProperty : System::IterateOver(doc->get_BuiltInDocumentProperties())) { std::cout << docProperty->get_Name() << std::endl; std::cout << System::String::Format(u"\tType:\t{0}", docProperty->get_Type()) << std::endl; // Some properties may store multiple values. if (System::ObjectExt::Is>>(docProperty->get_Value())) { for (auto&& value : System::IterateOver(System::AsCast>>(docProperty->get_Value()))) { std::cout << System::String::Format(u"\tValue:\t\"{0}\"", value) << std::endl; } } else { std::cout << System::String::Format(u"\tValue:\t\"{0}\"", docProperty->get_Value()) << std::endl; } } ``` ## See Also * Class [DocumentPropertyCollection](../documentpropertycollection/) * Namespace [Aspose::Words::Properties](../) * Library [Aspose.Words for C++](../../)
