Hey guys,

I am doing a request to this controller:

        [ResponseType(typeof(Book))]
        public async Task<IHttpActionResult> PostBook(Book book)
        {
            if (!ModelState.IsValid)
            {
                return BadRequest(ModelState);
            }

            string path = "C:\\Users\\af-costa\\Desktop\\TEST.docx";
            var stream = new MemoryStream();

            db.Books.Add(book);
            await db.SaveChangesAsync();

            // New code:
            // Load author name
            db.Entry(book).Reference(x => x.author).Load();

            var dto = new BookDTO()
            {
                Id = book.Id,
                Title = book.Title,
                AuthorName = book.author.name
            };

            Table customTable = createTable(book.author.name, book.Title);
            stream = createDocument(customTable);

            return CreatedAtRoute("DefaultApi", new { id = book.Id }, dto);
        }

the createDocument retrives me a memoryStream, i basicly need to download the file on the stream that i get from the openXml, in this method:

 private void createDocument(Table customTable)
        {
            var stream = new MemoryStream();
            // Create a Wordprocessing document. 
            using (WordprocessingDocument package = WordprocessingDocument.Create("Test1", WordprocessingDocumentType.Document))
            {
                // Add a new main document part. 
                package.AddMainDocumentPart();

                // Create the Document DOM. 
                package.MainDocumentPart.Document =
                  new Document(
                    new Body(
                      new Paragraph(
                        new Run(
                          new Table(customTable)))));

                // Save changes to the main document part. 
                package.MainDocumentPart.Document.Save();
            }
            stream.Seek(0, SeekOrigin.Begin);
 
        }

i don't know very well how can i download that file, basicly i want to create a document with a table, and download it when the user performs a request to
that access point, any help?

Hi FilipeCosrta,

Have you created the document correctly?

If you have, I would suggest you try below code to download file.

        [HttpGet]
        [Route("api/values/DownLoad")]
        public HttpResponseMessage DownLoad()
        {
            string filePath = @"full file path";
            HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.OK);
            var stream = new FileStream(filePath, FileMode.Open, FileAccess.Read);
            result.Content = new StreamContent(stream);
            result.Content.Headers.ContentType =
                new MediaTypeHeaderValue("application/octet-stream");
            result.Content.Headers.ContentDisposition= new ContentDispositionHeaderValue("attachment")
            {
                FileName = "file name.docx"
            };

            return result;
        }

Best Regards,

Edward
