//Load an existing Word document
WordDocument wordDocument = new WordDocument(fileStream, FormatType.Automatic);

Step 5: Convert Word document to PDF

Convert the Word document into a PDF document using the DocIORenderer.

c#
//Create an instance of DocIORenderer
DocIORenderer renderer = new DocIORenderer();
//Convert Word document into PDF document
PdfDocument pdfDocument = renderer.ConvertToPDF(wordDocument);

Step 6: Save the PDF file

Save the converted PDF document to a file stream.

Run

c#
//Save the PDF file to file system   
FileStream outputStream = new FileStream(Path.GetFullPath(@"Output/WordToPDF.pdf"), FileMode.Create, FileAccess.ReadWrite, FileShare.ReadWrite);
pdfDocument.Save(outputStream);
// Close resources explicitly
outputStream.Close();
pdfDocument.Close();
wordDocument.Close();
fileStream.Close();
