- Get a specified paragraph of the section using Section.Paragraphs[] property.
- Add a section break to the end of the paragraph using Paragraph.InsertSectionBreak() method.
- Save the result document using Document.SaveToFile() method.
- C#
using Spire.Doc;
using Spire.Doc.Documents;
namespace InsertSectionBreak
{
class Program
{
static void Main(string[] args)
{
//Create a Document instance
Document doc = new Document();
//Load a Word document
doc.LoadFromFile("sample.docx");
//Get the first section in the document
Section sec = doc.Sections[0];
//Get the second paragraph in the section
Paragraph para = sec.Paragraphs[1];
//Insert a continuous section break
para.InsertSectionBreak(SectionBreakType.NoBreak);
//Save the result document
doc.SaveToFile("InsertSectionBreak.docx", FileFormat.Docx);

Remove Section Breaks in Word in C#
To delete all sections breaks in a Word document, we need to access the first section in the document, then copy the contents of the other sections to the first section and delete them. The following are the detailed steps:
- Create a Document instance.
- Load a Word document using Document.LoadFromFile() method.
- Get the first section using Document.Sections[] property.
- Iterate through other sections in the document.
- Get the second section, and then iterate through to get its child objects.
- Clone the child objects of the second section and add them to the first section using Section.Body.ChildObjects.Add() method.
- Delete the second section using Document.Sections.Remove() method.
- Repeat the process to copy and delete the remaining sections.
- Save the result document using Document.SaveToFile() method.
- C#
using Spire.Doc;
namespace DeleteSectionBreak
{
class Program
{
static void Main(string[] args)
{
//Create a Document instance
Document doc = new Document();
//Load a Word document
doc.LoadFromFile("Report.docx");
//Get the first section in the document
Section sec = doc.Sections[0];
//Iterate through other sections in the document
for (int i = 0; i < doc.Sections.Count - 1; i++)
{
//Get the second section in the document
Section section = doc.Sections[1];
//Iterate through all child objects of the second section
for (int j = 0; j < section.Body.ChildObjects.Count; j++)
{
//Get the child objects
DocumentObject obj = section.Body.ChildObjects[j];
//Clone the child objects to the first section
sec.Body.ChildObjects.Add(obj.Clone());
}
//Remove the second section
doc.Sections.Remove(section);
}
//Save the result document
doc.SaveToFile("RemoveSectionBreaks.docx", FileFormat.Docx);
}
}

- Set the before and after spacing for the paragraph using Paragraph.Format.BeforeSpacing and Paragraph.Format.AfterSpacing properties.
- Add another paragraph and set line spacing in the paragraph using Paragraph.Format.LineSpacing property.
- Save the result document using Document.SaveToFile() method.
- C#
- VB.NET
using Spire.Doc;
using Spire.Doc.Documents;
namespace SetSpacing
{
class Program
{
static void Main(string[] args)
{
//Create a Document instance
Document document = new Document();
//Add a section
Section section = document.AddSection();
//Add a paragraph
Paragraph paragraph = section.AddParagraph();
paragraph.AppendText("Spire.Doc for .NET is a professional Word .NET library specifically designed for developers to " +
"create, read, write, convert, compare and print Word documents on any .NET platform " +
"(Target .NET Framework, .NET Core, .NET Standard, .NET 5.0, .NET 6.0, Xamarin & Mono Android ) with fast and high quality performance.");
//Set spacing before the paragraph
paragraph.Format.BeforeSpacing = 30;

//Save the result document
document.SaveToFile("SetSpacing.docx", FileFormat.Docx);
}
