Hi,

Check the following link, I think that will help you

https://github.com/smartinmedia/Net-Core-DocX-HTML-To-PDF-Converter

string locationOfLibreOfficeSoffice = @"C:\PortableApps\LibreOfficePortable\App\libreoffice\program\soffice.exe";

var docxLocation = "MyWordDocument.docx";

var rep = new ReportGenerator(locationOfLibreOfficeSoffice);

//Convert from DOCX to PDF
test.Convert(docxLocation, Path.Combine(Path.GetDirectoryName(docxLocation), "Test-Template-out.pdf"));

//Convert from DOCX to HTML
test.Convert(docxLocation, Path.Combine(Path.GetDirectoryName(docxLocation), "Test-Template-out.html"));

Hi,

You need to install the correct version of MS Office on your server, otherwise your code won't be working. If you don't want to install MS Office on server, you can use a third party library like Spire.Doc to implement the Word to PDF conversion.
using System;
using Spire.Doc;
using Spire.Doc.Documents;

namespace DoctoPDF
{
    class toPDF
    {
        static void Main(string[] args)
        {
            //Load a Word document
            Document document = new Document();
            document.LoadFromFile(@"E:\work\documents\TestSample.docx");
            //Convert Word to PDF
            document.SaveToFile("toPDF.PDF", FileFormat.PDF);
        }
    }
}

You can convert the Word document to PDF using the DocumentConverter on your server. Here is the code you can use:
using (DocumentConverter documentConverter = new DocumentConverter())
{
   var input = @"C:\Input\word.doc");
   var output = @"C:\Output\output.pdf");
   var jobData = DocumentConverterJobs.CreateJobData(input, output, DocumentFormat.Pdf);
   jobData.JobName = "conversion job";

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

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

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

Hi, what do you mean by "i am using 12.0 version dll and i am hold that dll in bin".
Note that you cannot use PIA as a private assembly, it needs to be registered in GAC. In other words you need an installed MS Office on your deployed machine. If this is not your problem then you should look take a look at the problems of using server-side automation of office, it is possible that you are experiencing some of the issues listed there.

Nevertheless as a workaround may I suggest you to try out this .NET component for word processing. It has a rather straightforward API, for example check this article how you can convert the Word file into a PDF file in C#. Also if interested you even have a direct API for exporting you PDF in ASP.NET.
