C# Text to PDF (Code Example Tutorial)

Create a Visual Studio Project

Open Microsoft Visual Studio. Click on Create New Project. Select the template "Console Application" for simplicity, but you can use Windows Forms, ASP.NET Web Forms, MVC, Web APIs, or any template as per your needs.

Select Next, Name the Project, Select Target Framework, and press Create. A new console project will be created.

Install-Package IronPdf

Press Enter.

Installation progress in the Package Manager Console

This will install the IronPDF library to be able to use all the functionalities provided by this library anywhere in the project.

Convert Text to PDF

Next, let's address the main task here --- converting C# text into a PDF file.

Firstly, reference the IronPDF library in the program.cs file. Write the following code snippet at the top of the file.

using IronPdf;

using IronPdf;

Imports IronPdf

Next, write the following code inside the main function. This code will convert text to PDF.

// Create an instance of ChromePdfRenderer, which is responsible for rendering HTML into PDF
ChromePdfRenderer renderer = new ChromePdfRenderer(); 

// Render a simple HTML string as a PDF document
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>This is my PDF</h1><p>This is generated for the tutorial of C# txt to PDF</p>");

// Save the generated PDF document to a specified path
pdf.SaveAs(@"D:\Iron Software\textToPDF\myFirstPDF.pdf");

// Create an instance of ChromePdfRenderer, which is responsible for rendering HTML into PDF
ChromePdfRenderer renderer = new ChromePdfRenderer(); 

// Render a simple HTML string as a PDF document
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>This is my PDF</h1><p>This is generated for the tutorial of C# txt to PDF</p>");

// Save the generated PDF document to a specified path
pdf.SaveAs(@"D:\Iron Software\textToPDF\myFirstPDF.pdf");

' Create an instance of ChromePdfRenderer, which is responsible for rendering HTML into PDF

Dim renderer As New ChromePdfRenderer()



' Render a simple HTML string as a PDF document

Dim pdf As PdfDocument = renderer.RenderHtmlAsPdf("<h1>This is my PDF</h1><p>This is generated for the tutorial of C# txt to PDF</p>")



' Save the generated PDF document to a specified path

pdf.SaveAs("D:\Iron Software\textToPDF\myFirstPDF.pdf")

Code Explanation

Firstly, create the object of the ChromePdfRenderer. This object is responsible for converting text to PDF. In the second line, the RenderHtmlAsPdf function is called with the reference of the renderer object.

This will generate a PDF from the text passed in the argument of this function. That PDF will then be temporarily stored as a PDF Document type.

Finally, the newly generated PDF file is saved to the local drive using the SaveAs function. Pass the path as an argument in the SaveAs function.

Output

This is the output of the above code. It is very easy to generate PDF programmatically from text.

TXT File to PDF file

In the above example, it shows how to convert simple TXT to PDF. Now, this example will demonstrate how to convert a text document into a PDF document.

Given a sample source TXT file as shown below.

The sample TXT file

The following code will convert a text file to PDF.

First, add the following namespace:

using System.IO;

using System.IO;

Imports System.IO

Write the following code snippet inside the main function.

// Read all text from a TXT file into a string
string text = File.ReadAllText(@"D:\Iron Software\textToPDF\myTxtFile.txt");

// Use the ChromePdfRenderer to render the text as a PDF document
ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf(text);

// Save the resulting PDF file to a specified location
pdf.SaveAs(@"D:\Iron Software\textToPDF\textFileToPDF.pdf");

// Read all text from a TXT file into a string
string text = File.ReadAllText(@"D:\Iron Software\textToPDF\myTxtFile.txt");

// Use the ChromePdfRenderer to render the text as a PDF document
ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf(text);

// Save the resulting PDF file to a specified location
pdf.SaveAs(@"D:\Iron Software\textToPDF\textFileToPDF.pdf");

' Read all text from a TXT file into a string

Dim text As String = File.ReadAllText("D:\Iron Software\textToPDF\myTxtFile.txt")



' Use the ChromePdfRenderer to render the text as a PDF document

Dim renderer As New ChromePdfRenderer()

Dim pdf As PdfDocument = renderer.RenderHtmlAsPdf(text)



' Save the resulting PDF file to a specified location

pdf.SaveAs("D:\Iron Software\textToPDF\textFileToPDF.pdf")

File.ReadAllText will read all the text from the file specified in the argument of the function. This text is then held in a string variable.

This variable is then passed as an argument of the RenderHtmlAsPdf function. This function will convert text into a PDF document.

Finally, specify the output filename in the SaveAs function.

Output

The output PDF file from a TXT file

In the above example, it is very easy to convert text into a new PDF document.

Add Watermark

Let's add a watermark to this newly created PDF. Watermarks can help to avoid the misuse of documents. You can set your watermark as per your needs. Let's consider the following example:

// Apply a watermark to the PDF with specified text and layout properties
pdf.ApplyWatermark("<h1>my Watermark</h1>", 45, 45, IronPdf.Editing.VerticalAlignment.Top, IronPdf.Editing.HorizontalAlignment.Center);

// Save the PDF with the watermark applied
pdf.SaveAs(@"D:\Iron Software\textToPDF\myFirstPDF.pdf");

// Apply a watermark to the PDF with specified text and layout properties
pdf.ApplyWatermark("<h1>my Watermark</h1>", 45, 45, IronPdf.Editing.VerticalAlignment.Top, IronPdf.Editing.HorizontalAlignment.Center);

// Save the PDF with the watermark applied
pdf.SaveAs(@"D:\Iron Software\textToPDF\myFirstPDF.pdf");

' Apply a watermark to the PDF with specified text and layout properties

pdf.ApplyWatermark("<h1>my Watermark</h1>", 45, 45, IronPdf.Editing.VerticalAlignment.Top, IronPdf.Editing.HorizontalAlignment.Center)



' Save the PDF with the watermark applied

pdf.SaveAs("D:\Iron Software\textToPDF\myFirstPDF.pdf")

The pdf variable holds a PdfDocument type. The ApplyWatermark function will add a watermark to the document. Pass your watermark text as an argument of the function such as "my watermark" as an example. The second argument is the watermark's rotation angle. The third and fourth arguments specify the vertical and horizontal alignment of the watermark.

Output

The following is the output generated by the sample code:

The PDF file with the watermark in the center

Print a PDF Document

Printing a PDF document using IronPDF is very easy --- just write the following line of code:

// Print the PDF document to the default printer
pdf.Print();

// Print the PDF document to the default printer
pdf.Print();

' Print the PDF document to the default printer

pdf.Print()

This will print a PDF document on your default printer. There are multiple printer settings available, and you can choose as per your requirements. For more details regarding PDF print settings, please refer to this PDF Printing Guide.
