        {
			using (Viewer viewer = new Viewer(() => GetFileFromFtp("sample.docx")))
            {
                HtmlViewOptions viewOptions = HtmlViewOptions.ForEmbeddedResources();                
                viewer.View(viewOptions);
            }
        }
                
        private static Stream GetFileFromFtp(string filePath)
        {
            Uri uri = new Uri(filePath);
            FtpWebRequest request = CreateRequest(uri);
            using (WebResponse response = request.GetResponse())
                return GetFileStream(response);
        }

        private static FtpWebRequest CreateRequest(Uri uri)
        {
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create(uri);
            request.Method = WebRequestMethods.Ftp.DownloadFile;
            return request;
        }

        private static Stream GetFileStream(WebResponse response)
        {
            MemoryStream fileStream = new MemoryStream();
            using (Stream responseStream = response.GetResponseStream())
                responseStream.CopyTo(fileStream);
            fileStream.Position = 0;
            return fileStream;
