Spire.PDF for .NET is a PDF library which enables users to handle the whole PDF document with wide range of tasks in C#, VB.NET. Spire.PDF supports to create PDF links, extract PDF links, update PDF links and remove PDF links from a PDF file. This article mainly shows how to extract and update link from a PDF file in C#.
Before the steps and codes, please check the original PDF file at first:
Firstly we need to create a new Document object and load a PDF file which needs to extract and update the links. The links are represented as annotations in a PDF file. Before extract and update the link from a PDF file, we need to extract all the AnnotationsWidget objects.
The following code snippet shows you how to extract links from the PDF file.
//Load an existing PDF file
PdfDocument document = new PdfDocument();
document.LoadFromFile(@"..\..\output.pdf");
//Get the first page
PdfPageBase page = document.Pages[0];
//Get the annotation collection
PdfAnnotationCollection widgetCollection = page.AnnotationsWidget;
//Verify whether widgetCollection is not null or not
if (widgetCollection.Count > 0)
{
foreach (var obj in widgetCollection)
{
//Get the TextWebLink Annotation
if (obj is PdfTextWebLinkAnnotationWidget)
{
PdfTextWebLinkAnnotationWidget link = obj as PdfTextWebLinkAnnotationWidget;
The following code snippet shows you how to update the link in PDF file
//Change the url of TextWebLink Annotation
link.Url = "http://www.e-iceblue.com/Introduce/pdf-for-net-introduce.html";
//Saves PDF document to file.
document.SaveToFile("sample.pdf");
This picture will show you the link has been updated in the PDF file.

- 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);
}
