Html page Convert byte and store in database

using System.IO;
using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.tool.xml;
using iTextSharp.tool.xml.pipeline.html;
using iTextSharp.tool.xml.parser;

public byte[] ConvertHtmlToPdf(string htmlContent)
{
    byte[] pdfBytes;

    using (var memoryStream = new MemoryStream())
    {
        using (var document = new Document())
        {
            var writer = PdfWriter.GetInstance(document, memoryStream);
            document.Open();

            using (var htmlStream = new StringReader(htmlContent))
            {
                var xmlWorkerHelper = XMLWorkerHelper.GetInstance();
                xmlWorkerHelper.ParseXHtml(writer, document, htmlStream);
            }
        }

        pdfBytes = memoryStream.ToArray();
    }

    return pdfBytes;
}

When displaying the PDF, retrieve the byte array from the database and return it as a response to the client:

public IActionResult DisplayPdf()
{
    // Retrieve the PDF byte array from the database based on the desired document ID
    byte[] pdfBytes = RetrievePdfBytesFromDatabase();

    // Return the PDF as a response
    return File(pdfBytes, "application/pdf");
}

By returning the PDF as a response with the appropriate MIME type ("application/pdf"), the browser will display the PDF to the user.

1. Evaluate the HTML structure: Review the HTML code and ensure that the content you want to display on a single page is properly organized within appropriate HTML tags (e.g., div, section, or table).

2. Adjust CSS styles: Modify the CSS styles associated with the HTML content to control the layout and pagination. You can use CSS properties like page-break-before, page-break-after, and page-break-inside to control page breaks and ensure the desired content is displayed on a single page.

3. Test the rendering: Before converting the HTML to bytes and storing it in the database, test the HTML page in a web browser to confirm that the content is displaying correctly and adhering to the desired page layout.

4. Convert to bytes: Use iText or any other suitable library to convert the HTML page to bytes. Ensure that you are capturing the entire HTML content and any associated CSS or JavaScript files, if required.

5. Store in the database: Save the byte array representing the HTML page in the appropriate column of your database table. Make sure you use the appropriate data type (e.g., BLOB or VARBINARY) to store binary data.

6. Retrieve and display: When retrieving the HTML content from the database, convert the byte array back to HTML and render it in the desired format. Ensure that the CSS styles are properly applied during rendering to maintain the intended layout and pagination.
