Shows how to use SECTION and SECTIONPAGES fields to number pages by sections.

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

builder.ParagraphFormat.Alignment = ParagraphAlignment.Right;

// A SECTION field displays the number of the section it is in.
builder.Write("Section ");
FieldSection fieldSection = (FieldSection)builder.InsertField(FieldType.FieldSection, true);

Assert.AreEqual(" SECTION ", fieldSection.GetFieldCode());

// A PAGE field displays the number of the page it is in.
builder.Write("\nPage ");
FieldPage fieldPage = (FieldPage)builder.InsertField(FieldType.FieldPage, true);

Assert.AreEqual(" PAGE ", fieldPage.GetFieldCode());

// A SECTIONPAGES field displays the number of pages that the section it is in spans across.
builder.Write(" of ");
FieldSectionPages fieldSectionPages = (FieldSectionPages)builder.InsertField(FieldType.FieldSectionPages, true);

Assert.AreEqual(" SECTIONPAGES ", fieldSectionPages.GetFieldCode());

// Move out of the header back into the main document and insert two pages.
// All these pages will be in the first section. Our fields, which appear once every header,
// will number the current/total pages of this section.

// We can insert a new section with the document builder like this.
// This will affect the values displayed in the SECTION and SECTIONPAGES fields in all upcoming headers.

// The PAGE field will keep counting pages across the whole document.
// We can manually reset its count at each section to keep track of pages section-by-section.
builder.CurrentSection.PageSetup.RestartPageNumbering = true;

doc.Save(ArtifactsDir + "Field.SECTION.SECTIONPAGES.docx");
