                string contentType = parser.ContentType;
                byte[] fileContent = parser.FileContents;
                FileStream fileToupload = new FileStream("D:\\FileUpload\\" + fileName, FileMode.Create);
                fileToupload.Write(fileContent, 0, fileContent.Length);
                fileToupload.Close();
