How to get a processed pdf on the server and display it in a browser window without downloading the file

Currently I have a pdf that has several sheets in a database stored path, and what I do is get a new pdf with a file from the server file and what I need is to show that pdf in a new window without needing to download the file, what I get now is the download of the file:

//Existe el pdf en el servidor se agrega logica de negocio para retornar el traveler
                string ruta = Path.Combine(Proyecto.pathPDF, "ODT " + dtSpools.Rows[0][0].ToString() + ".pdf");
                int numeroPaginasPDF = SplitPDF.Instance.CantidadDePaginas(ruta) - int.Parse(dtSpools.Rows[0][2].ToString());                              
                Document doc = new Document();
                string nombreTemporal = "\ODT_" + NumeroControl + ".pdf";
                MemoryStream stream = new MemoryStream();
                Document document = new Document();
                PdfCopy writer = new PdfCopy(document, stream);
                writer.CloseStream = false;
                PdfImportedPage page = null;
                document.Open();                                   
                PdfReader reader = new PdfReader(ruta);                    
                page = writer.GetImportedPage(reader, numeroPaginasPDF);
                writer.AddPage(page);                        
                document.Close();
                reader.Close();

                Response.Clear();
                Response.ContentType = "application/pdf";
                Response.AddHeader("content-disposition", "attachment;filename=ODT_" + NumeroControl + ".pdf");                    
                //Response.Buffer = true;
                //Response.OutputStream.Write(stream.GetBuffer(), 0, stream.GetBuffer().Length);
                //Response.OutputStream.Flush();
                //Response.Flush();
                //Response.Close();
                //Response.End();
                //return new FileStreamResult(Response.OutputStream, "application/pdf");                                       
                Response.BinaryWrite(stream.ToArray());
                return File(stream.ToArray(), "application/pdf");      

and I send it to execute with the following link:

<td><a href='/LinkTraveler/ObtenerPDFTraveler/[email protected](a => a.NumberControl)&[email protected](b => b.ProjectID)' target="_blank">@Html.DisplayTextFor(m => m.NumberControl)</a></td>

I would thank you in advance for your help
