![]() ![]() it is a necessary step as you must close the response after doing s best approach. Closes the socket connection to a client. ![]() Sends all currently buffered output to the client, stops execution of the Writes a string of binary characters to the HTTP output stream. Sets the Cache-Control header to one of the values of. the complete response is finished processing. Gets or sets a value indicating whether to buffer output and send it after Response.AddHeader("Content-Disposition", "attachment filename=Invoice.pdf") Adds an HTTP header to the output stream Response.ContentType = "application/pdf" Gets or sets the HTTP MIME type of the output stream. Clears all content output from the buffer stream In the next step we will see how we can download the in memory generated PDF File.Īs we are using the stream so that we use response method to send the information to the client. This is all about first step which will generate the PDF file and we will later use this as an attachment. Now we add the created document to the memory stream and use the bytes of it as a in-memory reference to later attach to the email. PdfWriter writer = PdfWriter.GetInstance(pdfDoc, memoryStream) Then first open the document, parse by the html worker and then after completing the work close the document (dispose off the resources) managing the resource properly. Now we get the PDF and memory stream to create the instance and write the document. using (MemoryStream memoryStream = new MemoryStream()) Use the memory stream to reside the file in-memory. Parse the HTML string using HTMLWorker of Itextsharp library, HTMLWorker htmlparser = new HTMLWorker(pdfDoc) Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f) ![]() We are building the PDF document with default page size of A4 Page size. StringReader sr = new StringReader(sb.ToString()) After building the string we can read from the string as we have passed the generated string. Using (MemoryStream memoryStream = new MemoryStream()) HTMLWorker htmlparser = new HTMLWorker(pdfDoc) StringReader sr = new StringReader(sb.ToString()) ĭocument pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f) Now let's write the code for generating in-memory PDF from HTML string. Before proceeding further add the following references. I am using StringBuilder class for generating HTML string and pass to the parser for generating PDF. Sb.Append("Invoice was created on a computer and is valid without the signature and seal.") Sb.Append("A finance charge of 1.5% will be made on unpaid balances after 30 days.") Sb.Append("Creating a recognizable design solution based on the company's existing visual identity") Sb.Append("ADDRESS 796 Silver Harbour, TX 79273, US") Let's start building HTML string. StringBuilder sb = new StringBuilder() So our front end is all set and we need to apply the cs logic to perform operation. Let's create the button to perform the required operation. In this step we will first create a button which will do the rest of the work on Click event. Secondly, we can download/save the converted PDF by using HTTP Response Class which provides response to client and contains information about response in the form of headers and other piece of necessary information. In this article, we will see how we can convert a string of data to PDF and then send email with attached copy of generated PDF in C#.įirstly, we can convert the string of data to PDF by using Popular Library for rendering PDF in ItextSharp.
