            {

                FilePath = Path.GetFileName(FileUpload1.FileName);

                FileUpload1.SaveAs(Server.MapPath("~/") + FilePath);

                using (ZipFile zipfile = new ZipFile())

                {

                    zipfile.AddFile(FilePath);

                    zipfile.Save(Server.MapPath("~/") + FilePath);

                }

                Response.Write("File sucessfully uploaded and ziped");

                File.Delete(FilePath);

            }

        }

        catch (Exception ex)

        {

            Response.Write("Error in file uploading");
