    static void Main(string[] args)
    {
        // Set the license type for QuestPDF
        QuestPDF.Settings.License = LicenseType.Community;

        // Create a PDF document using the QuestPDF fluent API
        var document = Document.Create(container =>
        {
            // Define a page with content and a header with page numbers
            container.Page(page =>
            {
                page.Content().Text("Hello, QuestPDF!");

                // Add a centered header with page number and total pages
                page.Header().AlignCenter().Text(text =>
                {
                    text.Span("Page ");
                    text.CurrentPageNumber();
                    text.Span(" of ");
                    text.TotalPages();
                });
            });
        });

        // Generate and save the PDF document
        document.GeneratePdf("QuestPdfOutput.pdf");
    }
}

using QuestPDF.Fluent;
using QuestPDF.Infrastructure;

class Program
{
    static void Main(string[] args)
    {
        // Set the license type for QuestPDF
        QuestPDF.Settings.License = LicenseType.Community;

        // Create a PDF document using the QuestPDF fluent API
        var document = Document.Create(container =>
        {
            // Define a page with content and a header with page numbers
            container.Page(page =>
            {
                page.Content().Text("Hello, QuestPDF!");

                // Add a centered header with page number and total pages
                page.Header().AlignCenter().Text(text =>
                {
                    text.Span("Page ");
                    text.CurrentPageNumber();
                    text.Span(" of ");
                    text.TotalPages();
                });
            });
        });

        // Generate and save the PDF document
        document.GeneratePdf("QuestPdfOutput.pdf");
    }
}

Imports QuestPDF.Fluent
Imports QuestPDF.Infrastructure

Friend Class Program
	Shared Sub Main(ByVal args() As String)
		' Set the license type for QuestPDF
		QuestPDF.Settings.License = LicenseType.Community

		' Create a PDF document using the QuestPDF fluent API
		Dim document = Document.Create(Sub(container)
			' Define a page with content and a header with page numbers
			container.Page(Sub(page)
				page.Content().Text("Hello, QuestPDF!")

				' Add a centered header with page number and total pages
				page.Header().AlignCenter().Text(Sub(text)
					text.Span("Page ")

					text.TotalPages()
				End Sub)
			End Sub)
		End Sub)

		' Generate and save the PDF document
		document.GeneratePdf("QuestPdfOutput.pdf")
	End Sub
End Class

This QuestPDF code defines a simple document with a page number in the header. The CurrentPageNumber() and TotalPages() methods are used to dynamically generate the page number relative to each page.
