Before we start our topic, let us first play a game. At the top of this page, there are nine categories. When we move our mouse on .NET, a dropdown list which shows all e-iceblue .NET products is displayed as the picture below:
Imagine, if we demonstrate every product on .NET out of the dropdown list on the top, what will this page be? The webpage will be rambling and disordered. As a result, visitors will hardly search what they want and finally have to leave disappointedly.
By the same token, if we do not merge PDF files of similar content to one document, all the information of various classes will mix together. We have no choice but to spend much time on finding the right files. While our work turns more efficient when we use PDF merge function. Furthermore, opening more PDF files at the same time always annoys people in that the windows are mistakenly switched. Finally, merge PDF does not mean gathering tens of PDF files into one. More reasonable choice is to amalgamate PDF files of few pages into single one. Those of numerous pages should be combined with merged PDF files in one folder for the convenience of reading.
Spire.PDF for WPF, as a professional PDF component, is a best hand for users to merge multiple PDF files on WPF application with C#, VB.NET. The whole procedure can be performed by below three simple steps.
Step 1. Create a C#/VB.NET Project
- Free download and correctly install Spire.PDF for WPF on system.
- Create “PDF merge” project in WPF Application with C#/VB.NET.
- Add a button in MainWindow.
- Add Spire.Pdf.Wpf.dll and System.Drawing as references.
Step 2 Merge PDF Files into One
//pdf document list
String[] files = new String[]
{
@"D:\e-iceblue\Spire.PDF\Demos\Data\DigitalSignature.pdf",
@"D:\e-iceblue\Spire.PDF\Demos\Data\Sample2.pdf",
@"D:\e-iceblue\Spire.PDF\Demos\Data\ImageWaterMark.pdf"
};
'pdf document list
Dim files As [String]() = New [String]() {"D:\e-iceblue\Spire.PDF\Demos\Data\DigitalSignature.pdf", "D:\e-iceblue\Spire.PDF\Demos\Data\Sample2.pdf", "D:\e-iceblue\Spire.PDF\Demos\Data\ImageWaterMark.pdf"}
Step 2. Open the three PDF files in a new document and import all pages into a new one
//open pdf documents
PdfDocument[] docs = new PdfDocument[files.Length];
for (int i = 0; i < files.Length; i++)
{
docs[i] = new PdfDocument(files[i]);
}
//append document
docs[0].AppendPage(docs[1]);
//import pages
for (int i = 0; i < docs[2].Pages.Count; i = i + 2)
{
docs[0].InsertPage(docs[2], i);
}
'open pdf documents
Dim docs As PdfDocument() = New PdfDocument(files.Length - 1) {}
For i As Integer = 0 To files.Length - 1
docs(i) = New PdfDocument(files(i))
Next
'append document
docs(0).AppendPage(docs(1))
'import pages
Dim i As Integer = 0
While i < docs(2).Pages.Count
docs(0).InsertPage(docs(2), i)
i = i + 2
End While
Step 3. Save and Preview the Merged PDF File
docs[0].SaveToFile("MergeDocuments.pdf");
foreach (PdfDocument doc in docs)
{
doc.Close();
}
PDFDocumentViewer("MergeDocuments.pdf");
docs(0).SaveToFile("MergeDocuments.pdf")
For Each doc As PdfDocument In docs
doc.Close()
Next
PDFDocumentViewer("MergeDocuments.pdf")

Spire.PDF is a PDF document creation component that enables your .NET/Silverlight/WPF applications to read, write and manipulate PDF documents without using Adobe Acrobat.
Hyperlinks in PDF are a valuable feature that enables readers to effortlessly access a given webpage. By including hyperlinks in a PDF, it becomes easier to offer readers supplementary information about the document or direct them to relevant resources. When a reader clicks on a hyperlink, the corresponding page opens immediately in the browser. In this article, we will demonstrate how to add hyperlinks to existing text in a PDF document through .NET programs using Spire.PDF for .NET.
Install Spire.PDF for .NET
To begin with, you need to add the DLL files included in the Spire.PDF for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.
PM> Install-Package Spire.PDF
Insert a Hyperlink to Existing Text in PDF with C#/VB.NET
Hyperlinks in PDF documents are inserted to the page as annotation elements. Adding a hyperlink to existing text in a PDF document requires locating the text first. Once the location has been obtained, an object of PdfUriAnnotation class with the link can be created and added to the position. The detailed steps are as follows:
- Create an object of PdfDocument class and load a PDF file using PdfDocument.LoadFromFile() method.
- Get the first page using PdfDocument.Pages property.
- Create an object of PdfTextFinder class and set the finder options using PdfTextFinder.Options.Parameter property.
- Find the specified text in the page using PdfTextFinder.Find() method and get the third occurrence.
- Loop through the text bounds of the specified occurrence (because the text being searched may span multiple lines and have more than one bound, the retrieved text bounds are stored in a list to accommodate this variability).
- Create an object of PdfUriAnnotation class within the text bound and set the URL, border, and border color using properties under PdfUriAnnotation class.
- Insert the hyperlink to the page annotations using PdfPageBase.AnnotationsWidget.Add(PdfUriAnnotation) method.
- Save the PDF file using PdfDocument.SaveToFile() method.
- C#
- VB.NET
using Spire.Pdf;
using Spire.Pdf.Annotations;
using Spire.Pdf.Texts;
using System.Collections.Generic;
using System.Drawing;
using TextFindParameter = Spire.Pdf.Texts.TextFindParameter;
namespace ChangeHyperlink
{
internal class Program
{
static void Main(string[] args)
{
//Create an object of PdfDocument class
PdfDocument pdf = new PdfDocument();
//Load a PDF file
pdf.LoadFromFile("Sample.pdf");
//Get the first page
PdfPageBase page = pdf.Pages[0];
//Create an object of PdfTextFinder and set the finder options
PdfTextFinder finder = new PdfTextFinder(page);
finder.Options.Parameter = TextFindParameter.IgnoreCase;
//Find the specified text in the page and get the third occurrence
List<PdfTextFragment> collection = finder.Find("climate change");
PdfTextFragment fragment = collection[2];
//Loop through the text bounds of the specified occurrence
foreach (RectangleF bounds in fragment.Bounds)
{
//Create a hyperlink annotation
PdfUriAnnotation url = new PdfUriAnnotation(bounds);
//Set the URL of the hyperlink
url.Uri = "https://en.wikipedia.org/wiki/Climate_change";
//Set the border of the hyperlink annotation
url.Border = new PdfAnnotationBorder(1f);
//Set the color of the border
url.Color = Color.Blue;
//Add the hyperlink annotation to the page
page.Annotations.Add(url);
}
//Save the PDF file
pdf.SaveToFile("AddHyperlinks.pdf");
pdf.Dispose();
}
}

Digital Certificate, known as identity certificate, is an electronic document that uses a digital signature to bind together a public key with an identity. As long as the PDF digital certificate is created, it demonstrates the authority of a digital document. This section will introduce a solution to create PDF digital certificate for WPF via a WPF PDF component.
Spire.PDF for WPF , a WPF library which can fully control your PDF documents, enables you to create PDF digital certificate in a simple way. First, please see the effect of this digital certificate task as below picture:
Before viewing the code, please Download Spire.PDF for WPF and install it in system.
In this solution, first you need to load your .pfx file from system. Then, create a new instance of Spire.Pdf.Security.PdfCertificate class with two parameters passed, one is the certificate file and the other is the password of the imported .pfx file. After creating a PdfSignature class instance, you can add DocumentPermissions to be AllowComments, AllowFormFill and ForbidChanges.
When you create the PdfSignature class instance, there are four parameters. The parameter "page" enables you to choose which PDF page you decide to sign the digital certificate.
String pfxPath = @"..\Data\Demo.pfx"; PdfCertificate cert = new PdfCertificate(pfxPath, "e-iceblue"); PdfSignature signature = new PdfSignature(doc, page, cert, "demo"); signature.ContactInfo = "Harry Hu"; signature.Certificated = true; signature.DocumentPermissions = PdfCertificationFlags.AllowFormFill;
Dim pfxPath As String = "..\Data\Demo.pfx" Dim cert As New PdfCertificate(pfxPath, "e-iceblue") Dim signature As New PdfSignature(doc, page, cert, "demo") signature.ContactInfo = "Harry Hu" signature.Certificated = True signature.DocumentPermissions = PdfCertificationFlags.AllowFormFill

Image watermark can be used to beautify as well as specify your PDF document. A properly managed PDF document with suitable image watermark can both give a different feeling and show the content or background to its readers. For example, if your PDF document is about environment protection, you can insert an image related to this topic. Spire.PDF for WPF allows you to easily draw a PDF image watermark for WPF.
Before you start, please make sure that Spire.PDF for WPF (or Spire.Office for WPF) is correctly installed on your system. Please follow the below procedure to realize this task.
Step 1: Create a new project
- Create a new project in WPF Application
- Add a button in MainWindow and set the button Content property to be "Run".
- Add Spire.Pdf.Wpf.dll and System.Drawing as references. After adding the namespaces, you can view the below codes.
using System.Drawing;
using System.Drawing.Imaging;
using Spire.Pdf;
using Spire.Pdf.Graphics;
namespace WPFPDFwatermark
{
///
/// Interaction logic for MainWindow.xaml
///
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void button1_Click(object sender, RoutedEventArgs e)
{
}
}
}
Imports System.Drawing Imports System.Drawing.Imaging Imports Spire.Pdf Imports Spire.Pdf.Graphics Namespace WPFPDFwatermark ''' ''' Interaction logic for MainWindow.xaml ''' Public Partial Class MainWindow Inherits Window Public Sub New() InitializeComponent() End Sub Private Sub button1_Click(sender As Object, e As RoutedEventArgs) End Sub End Class End Namespace
Step 2: Create a new PDF document and draw image watermark in it
After creating a new PDF document and setting its margin, you need to add a page in it. And then, insert the image watermark in the page you just added.
//Create a pdf document.
PdfDocument doc = new PdfDocument();
//margin
PdfUnitConvertor unitCvtr = new PdfUnitConvertor();
PdfMargins margin = new PdfMargins();
margin.Top = unitCvtr.ConvertUnits(2.54f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
margin.Bottom = margin.Top;
margin.Left = unitCvtr.ConvertUnits(3.17f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
margin.Right = margin.Left;
// Create one page
PdfPageBase page = doc.Pages.Add(PdfPageSize.A4, margin);
System.Drawing.Image img = System.Drawing.Image.FromFile(@"D:\e-iceblue\Spire.PDF\Demos\Data\Backgroundimage.png");
page.BackgroundImage = img;
'Create a pdf document.
Dim doc As New PdfDocument()
'margin
Dim unitCvtr As New PdfUnitConvertor()
Dim margin As New PdfMargins()
margin.Top = unitCvtr.ConvertUnits(2.54F, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point)
margin.Bottom = margin.Top
margin.Left = unitCvtr.ConvertUnits(3.17F, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point)
margin.Right = margin.Left
' Create one page
Dim page As PdfPageBase = doc.Pages.Add(PdfPageSize.A4, margin)
Dim img As System.Drawing.Image = System.Drawing.Image.FromFile("D:\e-iceblue\Spire.PDF\Demos\Data\Backgroundimage.png")
page.BackgroundImage = img
Step 3: Draw page in PDF document
This step shows you to insert page header, title, icon and content in the page and set their formats. Actually, not all the PDF file must have a header or icon or reference content. So it is better to choose what you need according to your own situation.

Text enjoys the same popularity whatever it is in PDF documents or in word files. Without it, people can hardly show their real purpose even with the help of images, tables, graphics or hyperlinks. Spire.PDF for WPF not only enables you to easily draw text in PDF document, but also allows you to align, rotate, transform Text and set text font & color in minutes.
Before you start, please make sure that Spire.PDF for WPF (or Spire.Office for WPF) is correctly installed on your system. Please follow the below procedure to realize this task.
Step 1: Create a new project
- Create a new project in WPF Application
- Add a button in MainWindow and set the button Content property to be "Run".
- Add Spire.Pdf.Wpf.dll and System.Drawing as references. After adding the namespaces, you can view the below codes.
using System.Drawing;
using Spire.Pdf;
using Spire.Pdf.Graphics;
namespace WPFPDFtext
{
///
/// Interaction logic for MainWindow.xaml
///
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void button1_Click(object sender, RoutedEventArgs e)
{
}
}
}
Imports System.Drawing Imports Spire.Pdf Imports Spire.Pdf.Graphics Namespace WPFPDFtext ''' ''' Interaction logic for MainWindow.xaml ''' Public Partial Class MainWindow Inherits Window Public Sub New() InitializeComponent() End Sub Private Sub button1_Click(sender As Object, e As RoutedEventArgs) End Sub End Class End Namespace
Step 2: Draw text of various styles in PDF document
Create a new PDF document and add a page in it
//Create a pdf document.
PdfDocument doc = new PdfDocument();
// Create one page
PdfPageBase page = doc.Pages.Add();
'Create a pdf document. Dim doc As New PdfDocument() 'Create one page Dim page As PdfPageBase = doc.Pages.Add()
Draw text in the page
private static void DrawText(PdfPageBase page)
{
//save graphics state
PdfGraphicsState state = page.Canvas.Save();
//Draw text - brush
String text = "Text,turn Around! Go! Go! Go!";
PdfPen pen = PdfPens.DeepSkyBlue;
PdfSolidBrush brush = new PdfSolidBrush(System.Drawing.Color.Blue);
PdfStringFormat format = new PdfStringFormat();
PdfFont font = new PdfFont(PdfFontFamily.Helvetica, 18f, PdfFontStyle.Italic);
SizeF size = font.MeasureString(text, format);
RectangleF rctg
= new RectangleF(page.Canvas.ClientSize.Width / 2 + 10, 180,
size.Width / 3 * 2, size.Height * 3);
page.Canvas.DrawString(text, font, pen, brush, rctg, format);
//restor graphics
page.Canvas.Restore(state);
}
Private Shared Sub DrawText(page As PdfPageBase)
'save graphics state
Dim state As PdfGraphicsState = page.Canvas.Save()

Effective Screeshot:
PDF barcode is mainly used in commodity transaction which, to a large extent, increases efficiency and escapes human errors. The most frequently case we use barcode is that when we go shopping in the supermarket, the operator only needs to scan the barcodes, the price of the goods will automatically show. Obviously, all the information has been input in the customer data table system. Through barcode, people can easily find the details of a good in a short time. Since barcode is so wonderful, let me share a solution to draw barcode in PDF document.
Spire.PDF for WPF enables users to easily draw barcode in PDF document with C#, VB.NET for WPF. Before you start, please freely Download Spire.PDF (Spire.Office) and install it with .NET Framework 2.0 (or above) together on your system. The detail procedure can be shown below.
Step 1: Create a new project
- Create a new project in WPF Application
- Add a button in MainWindow and set the button Content property to be "Run".
