Examples

Shows how to delete all footers from a document.

Document doc = new Document(MyDir + "Header and footer types.docx");

// Iterate through each section and remove footers of every kind.
foreach (Section section in doc.OfType<Section>())
{
    // There are three kinds of footer and header types.
    // 1 -  The "First" header/footer, which only appears on the first page of a section.
    HeaderFooter footer = section.HeadersFooters[HeaderFooterType.FooterFirst];
    footer?.Remove();

    // 2 -  The "Primary" header/footer, which appears on odd pages.
    footer = section.HeadersFooters[HeaderFooterType.FooterPrimary];
    footer?.Remove();

    // 3 -  The "Even" header/footer, which appears on even pages. 
    footer = section.HeadersFooters[HeaderFooterType.FooterEven];
    footer?.Remove();

    Assert.AreEqual(0, section.HeadersFooters.Count(hf => !((HeaderFooter)hf).IsHeader));
}

doc.Save(ArtifactsDir + "HeaderFooter.RemoveFooters.docx");

Shows how to create a header and a footer.

Document doc = new 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.
HeaderFooter header = new HeaderFooter(doc, HeaderFooterType.HeaderPrimary);
doc.FirstSection.HeadersFooters.Add(header);

Paragraph para = header.AppendParagraph("My header.");

Assert.True(header.IsHeader);
Assert.True(para.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.
HeaderFooter footer = new HeaderFooter(doc, HeaderFooterType.FooterPrimary);
doc.FirstSection.HeadersFooters.Add(footer);

para = footer.AppendParagraph("My footer.");

Assert.False(footer.IsHeader);
Assert.True(para.IsEndOfHeaderFooter);

Assert.AreEqual(footer, para.ParentStory);
Assert.AreEqual(footer.ParentSection, para.ParentSection);
Assert.AreEqual(footer.ParentSection, header.ParentSection);

doc.Save(ArtifactsDir + "HeaderFooter.Create.docx");
