How to convert the PDF stored in a PdfDocument object to byte array?
In .NET PDF, you can convert the PDF stored in a PdfDocument object to byte array by creating a new Memory stream class and saving the PdfDocument as stream. This stream contains information about the PdfDocument object and can be converted to byte array.
C#
// Creates a new instance of PdfDocument class. PdfDocument document = new PdfDocument(); // Adds a page to the document. PdfPage page = document.Pages.Add(); // Creates Pdf graphics for the page. PdfGraphics g = page.Graphics; // Creates a solid brush PdfBrush brush = new PdfSolidBrush(Color.Black); // Sets the font. PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 20f); // Draws the text. g.DrawString("Hello world!", font, brush, new PointF(20, 20)); //Creates a new Memory stream MemoryStream stream = new MemoryStream(); // Saves the document as stream document.Save(stream); document.Close(true); // Converts the PdfDocument object to byte form. byte[] docBytes = stream.ToArray(); //Loads the byte array in PdfLoadedDocument PdfLoadedDocument ldoc = new PdfLoadedDocument(docBytes); //Saves the document and dispose it. ldoc.Save("sample.pdf"); ldoc.Close();
