I done it like this

MultipartFormDataContent multiContent = new MultipartFormDataContent();
            multiContent.Headers.ContentType.MediaType = "multipart/form-data";
            foreach (SelectedDocumentModel model in SelectedFileData)
            {                 
                var upfilebytes = File.ReadAllBytes(model.Path);
                multiContent.Add(new ByteArrayContent(upfilebytes, 0, upfilebytes.Count()), "notification_files", model.FileName);                        
            }
            multiContent.Add(new StringContent(notificationdetails[0]), "title");
            multiContent.Add(new StringContent(notificationdetails[1]), "description");
            multiContent.Add(new StringContent(notificationdetails[3]), "type");
            multiContent.Add(new StringContent(notificationdetails[7]), "send_text_message");
            multiContent.Add(new StringContent(notificationdetails[2]), "text_message");
            multiContent.Add(new StringContent(notificationdetails[8]), "send_email");
            multiContent.Add(new StringContent(notificationdetails[9]), "notification_type");

            HttpClient client = new HttpClient();                         
            client.DefaultRequestHeaders.Authorization =
            new AuthenticationHeaderValue("bearer",Settings.AuthToken);         
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
