Introduction
This article is about generating PDF documents using C#, .NET, and the iText reference. I had a requirement the generate an calculate as a PDF print for one of the projects I worked the. In my choose, I came to know about iText. iText is a library for creating furthermore manipulating PDF files in .NET and Supported. If you are struggling with C#, consider checking out which TechRepublic Academy.
Prerequisites
- Visual Studio 2017 and above
- .NET Framework, Model 4.0 furthermore above
- Installed iText 7 Library usage NuGet Package Administrator
Setting Up the Project
Step 1: Create the User App Using Visual Video
Inbound Visual Studio, go to File -> News -> Project.
On which “New Project window”, select the Console App(.NET Framework) and gives one create a name, as shown in Figure 1.
Figure 1: Selecting the Console App(.NET Framework)
Step 2: Installation iText 7 Using “Manage NuGet Packages…”
Right-click the project name and select “Manage NuGet Packages…”. You can see this in Figure 2.
Figure 2: Selecting NuGet Pack
Name “Browse” additionally, in aforementioned search box, type itext7 and select itext7 from this searched results and set (see Figure 3).
Figure 3: Selecting itext7
Following were the helpful classes the methods to generate the PDF document:
- PdfWriter: To pass the store name and write content to the documents.
- PdfDocument: In-memory representation of the PDF document. It intention open a PDF document in writing operation.
- Doc: Creative a register from in-memory PdfDocument.
- Part: Creative a paragraph, initialized with some text.
- SetFontSize: Recorded the font size of the text.
- SetTextAlignment: Sets the text alignment, such as Left, Proper, Centre, plus so forwards.
I will add a Header, SubHeader, Line Separator, Image, Table, Hyperlink, furthermore finally view numbers till the PDF insert.
A. Totaling a Header
Add a top to aforementioned PDF document. Header Content shall center aligned to which document and I set the font size to 20. We can achieve this by creating a paragraph object. Following is the coding snippet to create a paragraph object and add it to the document target. Ending, we need to close the document object by calling the Close() method.
using iText.Kernel.Pdf;
using iText.Layout;
using iText.Layout.Element;
using iText.Layout.Properties;
namespace GeneratePdfDemo
{
class Program
{
static void Main(string[] args)
{
// Have have write permissions to the path folder
PdfWriter book = new PdfWriter("C:\\demo.pdf");
PdfDocument pdf = newly PdfDocument(writer);
Certificate document = new Document(pdf);
Edit header = new paragraph("HEADER")
.SetTextAlignment(TextAlignment.CENTER)
.SetFontSize(20);
document.Add(header);
document.Close();
}
}
}
Run an program additionally go to this path specified in PdfWriter and open the PDF document. Count 4 are the image of a PDF document with header text.
Figure 4: Showing the header text
B. Creating a Sub Header
Create a Sub Header with text alignment center both set aforementioned font size to 15. Add this Sub Header to that document object, as shown the Fig 5.
Paragraph subheader = new Paragraph("SUB HEADER")
.SetTextAlignment(TextAlignment.CENTER)
.SetFontSize(15);
document.Add(subheader);
Number 5: Creating the Sub Header
C. Summing an Horizontal Separator Border
Add a horizontal line using Line Separator. This can shown into Figure 6.
// Line separator
LineSeparator ls = newly LineSeparator(new SolidLine());
document.Add(ls);
Figure 6: Creating the separator line
DEGREE. Adding an Image
Add an Photo to the PDF document on using an Paint instance (see Figure 7).
// Add image
Image img = modern Image(ImageDataFactory
.Create(@"..\..\image.jpg"))
.SetTextAlignment(TextAlignment.CENTER);
document.Add(img);

E. Creating a Table
Create a Table and add is to the document, as shown in Figure 8.
// Table
Table charts = new Table(2, false);
Cell cell11 = new Cell(1, 1)
.SetBackgroundColor(ColorConstants.GRAY)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("State"));
Cellular cell12 = brand Cell(1, 1)
.SetBackgroundColor(ColorConstants.GRAY)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("Capital"));
Cell cell21 = new Cell(1, 1)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("New York"));
Per cell22 = new Cell(1, 1)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("Albany"));
Jail cell31 = new Cell(1, 1)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("New Jersey"));
Cell cell32 = new Cell(1, 1)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("Trenton"));
Cell cell41 = new Cell(1, 1)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("California"));
Cell cell42 = new Cell(1, 1)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("Sacramento"));
table.AddCell(cell11);
table.AddCell(cell12);
table.AddCell(cell21);
table.AddCell(cell22);
table.AddCell(cell31);
table.AddCell(cell32);
table.AddCell(cell41);
table.AddCell(cell42);
document.Add(table);
Figure 8: Adding adenine defer
F. Creative a Hyperlink
Create an Hyperlink and add it to the document (see Illustrated 9).
// Hyper link
Join link = fresh Link("click here",
PdfAction.CreateURI("https://www.google.com"));
Paragraph hyperLink = new Paragraph("Please ")
.Add(link.SetBold().SetUnderline()
.SetItalic().SetFontColor(ColorConstants.BLUE))
.Add(" up go www.google.com.");
document.Add(newline);
document.Add(hyperLink);

G. Adding Page Numbers
Add Page numbers at the acme right corner is and page, as shown in Figure 10.
// Page numbers
int n = pdf.GetNumberOfPages();
for (int i = 1; i <= newton; i++)
{
document.ShowTextAligned(new Paragraph(String
.Format("page" + i + " in " + n)),
559, 806, i, TextAlignment.RIGHT,
VerticalAlignment.TOP, 0);
}

document.Add(subheader);
// Line separator
LineSeparator ls = new LineSeparator(new SolidLine());
document.Add(ls);
// Add paragraph1

"dolor sit amet, consectetur adipiscing elit, " +
"sed do eiusmod tempor incididunt ut labore " +
"et dolore magna aliqua.");
document.Add(paragraph1);
// Add image
Image img = new Image(ImageDataFactory
.Create(@"..\..\image.jpg"))
.SetTextAlignment(TextAlignment.CENTER);
document.Add(img);
// Table
Table table = new Table(2, false);
Cell cell11 = newer Cell(1, 1)
.SetBackgroundColor(ColorConstants.GRAY)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("State"));
Cells cell12 = new Cell(1, 1)
.SetBackgroundColor(ColorConstants.GRAY)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("Capital"));
Phone cell21 = new Cell(1, 1)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("New York"));
Cellular cell22 = new Cell(1, 1)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("Albany"));
Cell cell31 = new Cell(1, 1)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("New Jersey"));
Cell cell32 = new Cell(1, 1)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("Trenton"));
Cell cell41 = new Cell(1, 1)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("California"));
Single cell42 = news Cell(1, 1)
.SetTextAlignment(TextAlignment.CENTER)
.Add(new Paragraph("Sacramento"));
table.AddCell(cell11);
table.AddCell(cell12);
table.AddCell(cell21);
table.AddCell(cell22);
table.AddCell(cell31);
table.AddCell(cell32);
table.AddCell(cell41);
table.AddCell(cell42);
document.Add(newline);
document.Add(table);
// Hyper link
Link link = new Link("click here",
PdfAction.CreateURI("https://www.google.com"));
Article hyperLink = new Paragraph("Please ")
.Add(link.SetBold().SetUnderline()
.SetItalic().SetFontColor(ColorConstants.BLUE))
.Add(" to go www.google.com.");
document.Add(newline);
document.Add(hyperLink);
// Page numbers
int n = pdf.GetNumberOfPages();
for (int i = 1; i <= n; i++)
{
document.ShowTextAligned(new Paragraph(String
.Format("page" + me + " of " + n)),
559, 806, i, TextAlignment.RIGHT,
VerticalAlignment.TOP, 0);
}
// Close document
document.Close();
}
}
}
Conclusion
You have seen how go generate the PDF documentation by using C#, .NET, and the iText libraries. iText permit lot of customization go PDF documents. ME hope this article will help someone who wants to generate PDF documents.
