I have a PDF document (using iText 7/C# 4.01) that I am creating in a MemoryStream and at the end, I want to write it out to a file. Part of the reason I am creating it in a memory stream is that I want to stamp a header table and footers on it at the end and was hoping to avoid writing it to a file then reading the file back in, stamping, then writing out a new file (as the examples I keep finding on iText website seem to do). However, I seem to be having some sort of chicken/egg scenario in the below code. It seems that you have to Close() the document in order for iText to fully form it. However, if I Close() it, then I get an ObjectDisposedException when trying to write it (simplified example below). I have to be missing something simple here, right? Thanks
MemoryStream baos = new MemoryStream();
PdfWriter writer = new PdfWriter(baos);
PdfDocument pdfDocument = new PdfDocument(writer.SetSmartMode(true));
//writer.SetCloseStream(true);
//pdfDocument.SetCloseWriter(true);
//pdfDocument.SetCloseReader(true);
//pdfDocument.SetFlushUnusedObjects(true);
Document d = new Document(pdfDocument, iText.Kernel.Geom.PageSize.LETTER);
d.Add(new Paragraph("Hello world!"));
//d.Close();
FileStream file = new FileStream("C:\test.pdf",
FileMode.Create, FileAccess.Write);
baos. WriteTo(file);
file.Close();
//baos.Close();
//d.Close();
Try this
I dont have IDE for test, but i think this work
MemoryStream baos = new MemoryStream();
PdfWriter writer = new PdfWriter(baos);
PdfDocument pdfDocument = new PdfDocument(writer.SetSmartMode(true));
Document d = new Document(pdfDocument, iText.Kernel.Geom.PageSize.LETTER);
d.Add(new Paragraph("Hello world!"));
d.Close();
byte[] byte1 = baos.ToArray();
File(byte1, "application/pdf", "C:\\iTextTester\\test.pdf");
