Give the name of file of pdf and add in to header Response.ContentType = "application/pdf" ItextSharp : iText is a PDF library that allows you to CREATE, ADAPT. MemoryStream mstream = new MemoryStream(bytes) GhostScript : It is an interpreter for the PostScript language and for PDF. close the MemoryStream, grab all of the active bytes from the stream After all of the PDF "stuff" above is done and closed but **before** we GetInstance().ParseXHtml(writer, doc, srHtml) Using (var srHtml = new StringReader(finalHtml)) ![]() XMLWorker also reads from a TextReader and not directly from a string Read your html by database or file here and store it into finalHtml e.g. Using (var writer = PdfWriter.GetInstance(doc, ms)) Create a writer that's bound to our PDF abstraction and our stream Create an iTextSharp Document which is an abstraction of a PDF but **NOT** a PDF Create a stream that we can write to, in this case a MemoryStream Required namespace for conversions are: using iTextSharp.text Īnd for conversion and download file : // Create a byte array that will eventually hold our final PDF It has ability to convert HTML file in to pdf. Var pdf = pechkin.Convert(new ObjectConfig()Īgain, thank you mightymada - your answer is fantastic. Var pechkin = Factory.Create(new GlobalConfig()) The incoming HTML is actually assembled via HTML Agility pack (I'm automating invoice generations): public static byte PechkinPdf(string html) The above blog has specific instructions for how to include this package (it's a 32 bit dll and requires. There is a nuget package for Pechkin, but as the above poster mentions in his blog ( - I hope she doesn't mind me reposting it), there's a memory leak that's been fixed in this branch: I would one-up'd mightymada's answer if I had the reputation - I just implemented an asp.net HTML to PDF solution using Pechkin. Return new FileStreamResult(output, "application/pdf") XmlWorker.ParseXHtml(writer, document, input, null) Var xmlWorker = XMLWorkerHelper.GetInstance() ![]() Var writer = PdfWriter.GetInstance(document, output) Var output = new MemoryStream() // this MemoryStream is closed by FileStreamResult Using (var input = new MemoryStream(bytes)) Public ActionResult HtmlToPdf(string html) Public class PdfConverterController : Controller It uses iTextSharp's XmlWorkerHelper, so the incoming hmtl must be valid XHTML, so you may need to do some fixup depending on your input. I post it here because it is a complete example of current iTextSharp usage for the html -> pdf conversion (disregarding images, I haven't looked at that since my usage doesn't require it) It could be modfied to use a FileStream instead of MemoryStream for the output if that's what is needed. Please let us know if you need any further assistance.Here's what I was able to get working on version 5.4.2 (from the nuget install) to return a pdf response from an asp.net mvc controller.

I have attached generated PDF file for your kind reference Test_18.3.pdf. However, 00018.SPL file is rendered fine. A ticket with ID PDFNET-44433 has been logged in our issue management system as a feature request for the same. That is why the rendering of file fails with an exception.
