Hello,

Thanks for your inquiry.
Sorry, there is currently no way to directly convert a large number of Word documents to Pdf file, however, you can put the all Word documents that you want to convert them to Pdf to the same folder, then travel the folder and convert each Word document to Pdf file. I put the relevant code below for your reference.

Code: Select all

static void Main(string[] args)
        {

            string filePath = @"../../data/";
            List<FileInfo> FileList = FindFile(filePath);
         
            foreach (FileInfo File in FileList)
            {
               
                    Document doc = new Document();
                    doc.LoadFromFile(File.FullName);
                string resultName = Path.GetFileNameWithoutExtension(File.FullName);

                doc.SaveToFile(@"../../output/"+ resultName + ".pdf");
             

            }
           
        }



        public static List<FileInfo> FindFile(string sSourcePath)

        {

            List<FileInfo> list = new List<FileInfo>();
     
            DirectoryInfo theFolder = new DirectoryInfo(sSourcePath);

            FileInfo[] thefileInfo = theFolder.GetFiles("*.*", SearchOption.TopDirectoryOnly);

            foreach (FileInfo NextFile in thefileInfo) 
            {
                list.Add(NextFile);

            }

            return list;
        }

unfortunally this is only another way to convert each document one by one... this dont solve the issue..

mmm...

maybe a sort of thread parallelism? i can convert multiple docs one to one but at the same moment.. there is any way to try this?

im on c# .net 4.7.2

thanks in advance

maybe i have a kind of solution... not verified yet...

Code: Select all


        public List<Stream> DOCX_to_PDF_multi(List<Stream> list_FromStream, int maxParallel = 10)
        {
            List<Stream> list_ToStream = new List<Stream>();

            IList<System.Threading.Tasks.Task> tasks = new List<System.Threading.Tasks.Task>();

            foreach (Stream fromStream in list_FromStream)
            {
                tasks.Add(
                    System.Threading.Tasks.Task.Factory.StartNew(() =>
                    {
                        try
                        {
                            list_ToStream.Add(DOCX_to_PD2(fromStream));
                        }
                        catch (Exception ex)
                        {
                            Console.WriteLine(ex.ToString());
                            //continue
                        }
                    })
                );
            }

            System.Threading.Tasks.Task.WaitAll(tasks.ToArray());

            return list_ToStream;
        }

        public Stream DOCX_to_PDF(Stream FromStream)
        {
            Stream ToStream = new MemoryStream() as Stream;
            using (Document document = new Document(FromStream, Spire.Doc.FileFormat.Docx, true))
            {
                document.SaveToStream(ToStream, Spire.Doc.FileFormat.PDF);
            }

            return ToStream;
        }
