A Microsoft Word document can contain multiple sections. To create a section in a Microsoft Word, select the Insert/Break command and select a break type. The break specifies whether section starts on a new page or on the same page.

Programmatically inserting and removing sections can be used to customize documents produced during mail merge. If a document needs to have different content or parts of the content depending on some criteria, then you can create a “master” document that contains multiple sections and delete some of the sections before or after mail merge.


Shows how to add and remove sections in a document.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.Write("Section 1");
builder.Write("Section 2");

Assert.AreEqual("Section 1\x000cSection 2", doc.GetText().Trim());

// Delete the first section from the document.

Assert.AreEqual("Section 2", doc.GetText().Trim());

// Append a copy of what is now the first section to the end of the document.
int lastSectionIdx = doc.Sections.Count - 1;
Section newSection = doc.Sections[lastSectionIdx].Clone();

Assert.AreEqual("Section 2\x000cSection 2", doc.GetText().Trim());
