There are multiple options you can pick which will allow you to take a file and convert it to PDF; however, you will run into a limitation with certain file types as the scope of what file types are supported in solutions is limited. A solution you can look into using is the DocumentConverter provided in the LEADTOOLS SDK which will allow you to take over 150 different formats and convert them into a searchable PDF. You can try the following code to perform this conversion.
private static void DocumentConvert(string inputFile, string outputFile)
{
   using (DocumentConverter documentConverter = new DocumentConverter())
   {
      IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD);
      ocrEngine.Startup(null, null, null, null);
      documentConverter.SetOcrEngineInstance(ocrEngine, true);
      documentConverter.SetDocumentWriterInstance(new DocumentWriter());

     var inputDocument = DocumentFactory.LoadFromFile(inputFile, new LoadDocumentOptions());
      DocumentConverterJobData jobData = new DocumentConverterJobData()
      {
         Document = inputDocument,
         OutputDocumentFileName = outputFile,
         DocumentFormat = DocumentFormat.Pdf,
         AnnotationsMode = DocumentConverterAnnotationsMode.Embed,
         RasterImageBitsPerPixel = 0,
         RasterImageFormat = RasterImageFormat.Unknown
      };

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

If you have MS Office with at least the Office 2007 Save as PDF add-in, you can try to use the Microsoft.Office.Interop.Word methods to load the Word files by code and save as PDF.
If you don't have Office installed, you can use a library that doesn't depend on Office for loading Word files and saving PDF like leadtools or OpenOffice. For example on both libraries, see these links:

For converting any file (like Word, Excel, HTML, Powerpoint, Image, RTF), Spire.Office is the right tool to use. The code is simple and similiar:

For example: word to pdf conversion

Document document = new Document();
document.LoadFromFile(@"Demo.docx");
document.SaveToFile("toPDF.PDF", FileFormat.PDF);

More examples, please see:http://www.e-iceblue.com/Tutorials.html

Recently I had written an article about this topic, that covers how you can create a PDF from different format of documents (including HTML format). You can read the article here, http://www.c-sharpcorner.com/UploadFile/201fc1/spire-doc-net-library-for-cross-file-format-document-creati/
