How to Tutorial

2. Use the PDF .NET Library

Now that we have the software, we can generate PDFs, adjust settings, add custom text and images, and manipulate the PDFs to our project requirements.

In the below code, we have used a C# Form demonstrating simply how to create a PDF with the C# .NET library. In this example, we have a TextBox to write our own text and then just click on a button to make a PDF. The class ChromePdfRenderer offers the simplest possible way to generate PDF files from different sources including an HTML string, web URLs, or doc files under another renderer.

// C# Program to create PDF from TextBox input using IronPDF
using IronPdf;
using System.Windows.Forms;

namespace readpdf
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        // Event handler for the button click
        private void button1_Click(object sender, System.EventArgs e)
        {
            // Create a ChromePdfRenderer object to convert HTML to PDF
            var HtmlLine = new ChromePdfRenderer();

            // Retrieve the text from the TextBox
            string text = textBox1.Text;

            // Render the HTML as a PDF, wrapping the text in an <h1> tag
            using var pdf = HtmlLine.RenderHtmlAsPdf("<h1>" + text + "</h1>");

            // Save the PDF to a file called "custom.pdf"
            pdf.SaveAs("custom.pdf");

            // Show a confirmation message to the user
            MessageBox.Show("Done!");
        }
    }
}

// C# Program to create PDF from TextBox input using IronPDF
using IronPdf;
using System.Windows.Forms;

namespace readpdf
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        // Event handler for the button click
        private void button1_Click(object sender, System.EventArgs e)
        {
            // Create a ChromePdfRenderer object to convert HTML to PDF
            var HtmlLine = new ChromePdfRenderer();

            // Retrieve the text from the TextBox
            string text = textBox1.Text;

            // Render the HTML as a PDF, wrapping the text in an <h1> tag
            using var pdf = HtmlLine.RenderHtmlAsPdf("<h1>" + text + "</h1>");

            // Save the PDF to a file called "custom.pdf"
            pdf.SaveAs("custom.pdf");

            // Show a confirmation message to the user
            MessageBox.Show("Done!");
        }
    }
}

' C# Program to create PDF from TextBox input using IronPDF
Imports IronPdf
Imports System.Windows.Forms

Namespace readpdf
	Partial Public Class Form1
		Inherits Form

		Public Sub New()
			InitializeComponent()
		End Sub

		' Event handler for the button click
		Private Sub button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
			' Create a ChromePdfRenderer object to convert HTML to PDF
			Dim HtmlLine = New ChromePdfRenderer()

			' Retrieve the text from the TextBox
'INSTANT VB NOTE: The variable text was renamed since Visual Basic does not handle local variables named the same as class members well:
			Dim text_Conflict As String = textBox1.Text

			' Render the HTML as a PDF, wrapping the text in an <h1> tag
			Dim pdf = HtmlLine.RenderHtmlAsPdf("<h1>" & text_Conflict & "</h1>")

			' Save the PDF to a file called "custom.pdf"
			pdf.SaveAs("custom.pdf")

			' Show a confirmation message to the user
			MessageBox.Show("Done!")
		End Sub
	End Class
End Namespace

3. C# Form to PDF

We have used a C# Windows Forms App to show you the perfect output with custom text. In just a single click, the text in the TextBox gets converted to a custom PDF. This requires only a single-line code function and is easy to understand.
