                   {


                        string folderPath = "D:\\UPLOADS\\";

                        foreach (HttpPostedFile postfiles in FUAttchmnts.PostedFiles)
                        {
                            //Msg.Attachments.Add(new Attachment(FUAttchmnts.PostedFile.InputStream, FUAttchmnts.FileName));

                            string FileNm = "";

                            FileNm = System.IO.Path.GetFileName(postfiles.FileName.ToString());

                            //Save the File to the Directory (Folder).

                            FUAttchmnts.SaveAs(folderPath + Path.GetFileName(FileNm));

                            Msg.Attachments.Add(new Attachment(folderPath + Path.GetFileName(FileNm)));
                        }
