Examples

Shows how to create a header and a footer.

auto doc = System::MakeObject<Aspose::Words::Document>();

// Create a header and append a paragraph to it. The text in that paragraph
// will appear at the top of every page of this section, above the main body text.
auto header = System::MakeObject<Aspose::Words::HeaderFooter>(doc, Aspose::Words::HeaderFooterType::HeaderPrimary);
doc->get_FirstSection()->get_HeadersFooters()->Add(header);

System::SharedPtr<Aspose::Words::Paragraph> para = header->AppendParagraph(u"My header.");

ASSERT_TRUE(header->get_IsHeader());
ASSERT_TRUE(para->get_IsEndOfHeaderFooter());

// Create a footer and append a paragraph to it. The text in that paragraph
// will appear at the bottom of every page of this section, below the main body text.
auto footer = System::MakeObject<Aspose::Words::HeaderFooter>(doc, Aspose::Words::HeaderFooterType::FooterPrimary);
doc->get_FirstSection()->get_HeadersFooters()->Add(footer);

para = footer->AppendParagraph(u"My footer.");

ASSERT_FALSE(footer->get_IsHeader());
ASSERT_TRUE(para->get_IsEndOfHeaderFooter());

ASPOSE_ASSERT_EQ(footer, para->get_ParentStory());
ASPOSE_ASSERT_EQ(footer->get_ParentSection(), para->get_ParentSection());
ASPOSE_ASSERT_EQ(footer->get_ParentSection(), header->get_ParentSection());

doc->Save(get_ArtifactsDir() + u"HeaderFooter.Create.docx");

Shows how to delete all footers from a document.

auto doc = System::MakeObject<Aspose::Words::Document>(get_MyDir() + u"Header and footer types.docx");

// Iterate through each section and remove footers of every kind.
for (auto&& section : System::IterateOver(doc->LINQ_OfType<System::SharedPtr<Aspose::Words::Section> >()))

    System::SharedPtr<Aspose::Words::HeaderFooter> condExpression = footer;
    if (condExpression != nullptr)
    {
        condExpression->Remove();
    }

    // 2 -  The "Primary" header/footer, which appears on odd pages.
    footer = section->get_HeadersFooters()->idx_get(Aspose::Words::HeaderFooterType::FooterPrimary);
    System::SharedPtr<Aspose::Words::HeaderFooter> condExpression2 = footer;
    if (condExpression2 != nullptr)
    {
        condExpression2->Remove();
    }

    // 3 -  The "Even" header/footer, which appears on even pages.
    footer = section->get_HeadersFooters()->idx_get(Aspose::Words::HeaderFooterType::FooterEven);
    System::SharedPtr<Aspose::Words::HeaderFooter> condExpression3 = footer;
    if (condExpression3 != nullptr)
    {
        condExpression3->Remove();
    }

    ASSERT_EQ(0, section->get_HeadersFooters()->LINQ_Count(static_cast<System::Func<System::SharedPtr<Aspose::Words::Node>, bool>>(static_cast<std::function<bool(System::SharedPtr<Aspose::Words::Node> hf)>>([](System::SharedPtr<Aspose::Words::Node> hf) -> bool
    {
        return !(System::ExplicitCast<Aspose::Words::HeaderFooter>(hf))->get_IsHeader();
