Saving a pdf file opened in Adobe Reader by a process in c#

Anshit Hayaran

I am trying to open the file in Adobe Reader through "process" because Adobe reader can repair the corrupt file itself, but I need to “SaveAs” the file also from there at code level without manually saving it, is it possible in .net?

Code I am using :

Process p = new Process();
p.StartInfo.FileName = file;
p.Start();
//Code to Save As this file
p.Close();
inputDocument = PdfReader.Open(file, PdfDocumentOpenMode.Import);

You can pass the file path and save it using the DocumentConverter class as it can handle corrupted files. Here is some code which will help you get started:
using (DocumentConverter documentConverter = new DocumentConverter())
{
   var input = @"C:\Input\input.pdf"); // path to input file from process
   var output = @"C:\Output\output.pdf");
   var jobData = DocumentConverterJobs.CreateJobData(input, output, DocumentFormat.Pdf);
   jobData.JobName = "save pdf";

   var documentWriter = new DocumentWriter();
   documentConverter.SetDocumentWriterInstance(documentWriter);

   var renderingEngine = new AnnWinFormsRenderingEngine();
   documentConverter.SetAnnRenderingEngineInstance(renderingEngine);

   var job = documentConverter.Jobs.CreateJob(jobData);
   documentConverter.Jobs.RunJob(job);
}

Hello,

there is no such API from PdfReader. Only if you have access to the Adobe reader API.

To open the PDF with Process you need open with "UseShellExecute" and the Adobe must be the default handler configured in Windows.
ProcessStartInfo psi = new ProcessStartInfo(file);
        psi.UseShellExecute = true;
        Process.Start(psi);
