Creating a PDF from a RDLC Report in the Background

Question

I am running a month-end process and want to have it automatically create some of the reports that need to be created at that time. I am using rdlc reports. Is there a way to automatically create a PDF from a RDLC report in the background?

Answer 1

This is easy to do, you can render the report as a PDF, and save the resulting byte array as a PDF file on disk. To do this in the background, that's more a question of how your app is written. You can just spin up a new thread, or use a BackgroundWorker (if this is a WinForms app), etc. There, of course, may be multithreading issues to be aware of.

Warning[] warnings; string[] streamids; string mimeType; string encoding; string filenameExtension;  byte[] bytes = reportViewer.LocalReport.Render(     "PDF", null, out mimeType, out encoding, out filenameExtension,     out streamids, out warnings);  using (FileStream fs = new FileStream("output.pdf", FileMode.Create)) {     fs.Write(bytes, 0, bytes.Length); }
