I have found several open-source/freeware programs that allow you to convert .doc files to .pdf files, but they're all of the application/printer driver variety, with no SDK attached. I have found several programs that do have an SDK allowing you to convert .doc files to .pdf files, but they're all of the proprietary type, $2,000 a license or thereabouts. Does anyone know of any clean, inexpensive (preferably free) programmatic solution to my problem, using C# or VB.NET? Thanks!

Commented Feb 11, 2020 at 8:47 You can use docx2pdf to make this conversion: github.com/AlJohri/docx2pdf Commented Feb 18, 2020 at 7:33For people looking for a solution, this is much easier with LibreOffice. If you have docker installed, it is a simple command: docker "run" "--rm" "--entrypoint" "soffice" "-v" "$(pwd):/usr/src/project" "linuxserver/libreoffice:latest" "--headless" "--convert-to" "pdf" "--outdir" "/usr/src/project" "/usr/src/project/foo.docx"
Commented Feb 13, 2023 at 15:22 You can use ApyHub's Doc to PDF API - apyhub.com/utility/converter-doc-pdf Commented Mar 4 at 11:43Use a foreach loop instead of a for loop - it solved my problem.
int j = 0; foreach (Microsoft.Office.Interop.Word.Page p in pane.Pages) < var bits = p.EnhMetaFileBits; var target = path1 +j.ToString()+ "_image.doc"; try < using (var ms = new MemoryStream((byte[])(bits))) < var image = System.Drawing.Image.FromStream(ms); var pngTarget = Path.ChangeExtension(target, "png"); image.Save(pngTarget, System.Drawing.Imaging.ImageFormat.Png); >> catch (System.Exception ex) < MessageBox.Show(ex.Message); >j++; > Here is a modification of a program that worked for me. It uses Word 2007 with the Save As PDF add-in installed. It searches a directory for .doc files, opens them in Word and then saves them as a PDF. Note that you'll need to add a reference to Microsoft.Office.Interop.Word to the solution.
