Step 1: Create a new Visual Studio project

Now let's get started with creating a new project, open Visual Studio and create a new project as below.

Select create console application.

Provide project name and location.

Select .NET version

Create a new project.

Step 2: Add IronPDF library from NuGet package manager

Using the NuGet Package Manager in Visual Studio console application you can use the below command to add the IronPDF NuGet library.

Install-Package IronPdf

Install-Package IronPdf

Also, IronPDF can be installed using Visual Studio Package Manager.

Step 3: Create a Simple PDF file.

Generate PDF documents with ease using the IronPDF library. Now let's get started with a simple blank PDF file.

using IronPdf;

class Program
{
    static void Main()
    {
        // Set your IronPDF license key
        IronPdf.License.LicenseKey = "your key";

        // Create a new PDF document with specific dimensions (270x270 points)
        PdfDocument pdf = new PdfDocument(270, 270);

        // Save the blank PDF document to disk
        pdf.SaveAs("simple.pdf");
    }
}

using IronPdf;

class Program
{
    static void Main()
    {
        // Set your IronPDF license key
        IronPdf.License.LicenseKey = "your key";

        // Create a new PDF document with specific dimensions (270x270 points)
        PdfDocument pdf = new PdfDocument(270, 270);

        // Save the blank PDF document to disk
        pdf.SaveAs("simple.pdf");
    }
}

Imports IronPdf

Friend Class Program
	Shared Sub Main()
		' Set your IronPDF license key
		IronPdf.License.LicenseKey = "your key"

		' Create a new PDF document with specific dimensions (270x270 points)
		Dim pdf As New PdfDocument(270, 270)

		' Save the blank PDF document to disk
		pdf.SaveAs("simple.pdf")
	End Sub
End Class

Explanation of the Code

This program demonstrates how to use the IronPDF library to create a PDF document in C#. Here's what happens in the code:

1. License Key Setup: The program first sets the license key for the IronPDF library. This is necessary to use the full features of the library, as the license key ensures you have access to the full functionality (rather than being limited to a trial version).

2. Creating a PDF Document: The program then creates a new PDF document with a size of 270x270 points. A point is a unit of measurement in printing and is equivalent to 1/72 of an inch. Therefore, this would create a square document of roughly 3.75 inches by 3.75 inches.

3. Saving the PDF: After creating the blank document, the program saves the PDF with the filename "simple.pdf". Since no content is added to the document, the output will be a completely blank (black) PDF.

Step 4: Modify PDF files

using IronPdf;

class Program
{
    static void Main()
    {
        // Set your IronPDF license key
        IronPdf.License.LicenseKey = "your key";

        // Load the existing PDF document
        var pdf = new PdfDocument("simple.pdf");

        // Create a renderer for converting HTML to PDF
        var renderer = new ChromePdfRenderer();

        // Render HTML content as a PDF
        var pagePdf = renderer.RenderHtmlAsPdf("<h1>Awesome IronPDF Library</h1>");

        // Prepend the rendered page as the first page of the existing PDF
        pdf.PrependPdf(pagePdf);

        // Save the modified PDF with a new filename
        pdf.SaveAs("simple_WithTitle.pdf");
    }
}

using IronPdf;

class Program
{
    static void Main()
    {
        // Set your IronPDF license key
        IronPdf.License.LicenseKey = "your key";

        // Load the existing PDF document
        var pdf = new PdfDocument("simple.pdf");

        // Create a renderer for converting HTML to PDF
        var renderer = new ChromePdfRenderer();

        // Render HTML content as a PDF
        var pagePdf = renderer.RenderHtmlAsPdf("<h1>Awesome IronPDF Library</h1>");

        // Prepend the rendered page as the first page of the existing PDF
        pdf.PrependPdf(pagePdf);

        // Save the modified PDF with a new filename
        pdf.SaveAs("simple_WithTitle.pdf");
    }
}

Imports IronPdf

Friend Class Program
	Shared Sub Main()
		' Set your IronPDF license key
		IronPdf.License.LicenseKey = "your key"

		' Load the existing PDF document
		Dim pdf = New PdfDocument("simple.pdf")

		' Create a renderer for converting HTML to PDF
		Dim renderer = New ChromePdfRenderer()

		' Render HTML content as a PDF
		Dim pagePdf = renderer.RenderHtmlAsPdf("<h1>Awesome IronPDF Library</h1>")

		' Prepend the rendered page as the first page of the existing PDF
		pdf.PrependPdf(pagePdf)

		' Save the modified PDF with a new filename
		pdf.SaveAs("simple_WithTitle.pdf")
	End Sub
End Class

Code Explanation

1. License Key Setup: Set the IronPDF license key to enable the library's full functionality.

2. Loading an Existing PDF: Load an existing PDF file named "simple.pdf" into a new PdfDocument object. This is the PDF that will have a new cover page prepended to it.

3. Rendering HTML to PDF: Use a ChromePdfRenderer object to render HTML content into a PDF. In this example, the HTML content is a simple <h1> tag with the text "Awesome IronPDF Library", which is converted into a cover-page PDF using the RenderHtmlAsPdf method.

4. Prepending the Cover Page: Use the PrependPdf method to insert the cover page PDF (generated from the HTML) at the beginning of the existing PDF document.

5. Saving the Modified PDF: Save the modified PDF (with the new cover page) under the name "simple_WithTitle.pdf". The original content from "simple.pdf" is retained, but now it begins with the newly added title page.

Output PDF

Step 5: Adding Headers and Footers

using IronPdf;

class Program
{
    static void Main()
    {
        // Set your IronPDF license key
        IronPdf.License.LicenseKey = "your key";

        // Create a new HtmlToPdf renderer
        var renderer = new ChromePdfRenderer();

        // Define the HTML content
        string htmlContent = "<html><body><h1>IronPDF: An Awesome PDF Generation Library</h1><h2>Report</h2><p>This is a sample report.</p></body></html>";

        // Define headers and footers as HTML
        string headerHtml = "<div style='text-align: right;'>Page {page} of {total-pages}</div>";
        string footerHtml = "<div style='text-align: center;'>Confidential</div>";

        // Convert the HTML content to a PDF document
        var pdfDocument = renderer.RenderHtmlAsPdf(htmlContent);

        // Add headers and footers to the PDF document
        pdfDocument.AddHtmlHeadersAndFooters(new ChromePdfRenderOptions
        {
            HtmlHeader = new HtmlHeaderFooter() { HtmlFragment = headerHtml },
            HtmlFooter = new HtmlHeaderFooter() { HtmlFragment = footerHtml }
        });

        // Save the PDF document with headers and footers
        pdfDocument.SaveAs("report.pdf");
    }
}

using IronPdf;

class Program
{
    static void Main()
    {
        // Set your IronPDF license key
        IronPdf.License.LicenseKey = "your key";

        // Add headers and footers to the PDF document
        pdfDocument.AddHtmlHeadersAndFooters(new ChromePdfRenderOptions
        {
            HtmlHeader = new HtmlHeaderFooter() { HtmlFragment = headerHtml },
            HtmlFooter = new HtmlHeaderFooter() { HtmlFragment = footerHtml }
        });

        // Save the PDF document with headers and footers
        pdfDocument.SaveAs("report.pdf");
    }
}
