Shows how to work with a document’s custom properties.

auto doc = MakeObject<Document>();
SharedPtr<CustomDocumentProperties> properties = doc->get_CustomDocumentProperties();

ASSERT_EQ(0, properties->get_Count());

// Custom document properties are key-value pairs that we can add to the document.
properties->Add(u"Authorized", true);
properties->Add(u"Authorized By", String(u"John Doe"));
properties->Add(u"Authorized Date", System::DateTime::get_Today());
properties->Add(u"Authorized Revision", doc->get_BuiltInDocumentProperties()->get_RevisionNumber());
properties->Add(u"Authorized Amount", 123.45);

// The collection sorts the custom properties in alphabetic order.
ASSERT_EQ(1, properties->IndexOf(u"Authorized Amount"));
ASSERT_EQ(5, properties->get_Count());

// Print every custom property in the document.
    SharedPtr<System::Collections::Generic::IEnumerator<SharedPtr<DocumentProperty>>> enumerator = properties->GetEnumerator();
    while (enumerator->MoveNext())
        std::cout << String::Format(u"Name: \"{0}\"\n\tType: \"{1}\"\n\tValue: \"{2}\"", enumerator->get_Current()->get_Name(),

// Display the value of a custom property using a DOCPROPERTY field.
auto builder = MakeObject<DocumentBuilder>(doc);
auto field = System::ExplicitCast<FieldDocProperty>(builder->InsertField(u" DOCPROPERTY \"Authorized By\""));

// We can find these custom properties in Microsoft Word via "File" -> "Properties" > "Advanced Properties" > "Custom".
doc->Save(ArtifactsDir + u"DocumentProperties.DocumentPropertyCollection.docx");

// Below are three ways or removing custom properties from a document.
// 1 -  Remove by index:

ASSERT_FALSE(properties->Contains(u"Authorized Amount"));
ASSERT_EQ(4, properties->get_Count());

// 2 -  Remove by name:
properties->Remove(u"Authorized Revision");

ASSERT_FALSE(properties->Contains(u"Authorized Revision"));
ASSERT_EQ(3, properties->get_Count());

// 3 -  Empty the entire collection at once:

ASSERT_EQ(0, properties->get_Count());
