實現點擊下載功能，能夠一次性下載多個附件。具體實現代碼以下 ：

 private void Com_XZTP_FJ(string maiId, string wtfjdz, string CLwtfjdz, string type)
        {
            ArrayList all = new ArrayList();
            if (!string.IsNullOrEmpty(wtfjdz))
            {
                ArrayList fjarry = spiltBySign(wtfjdz, "|");
                all.AddRange(fjarry);
            }
            if (!string.IsNullOrEmpty(CLwtfjdz))
            {
                ArrayList wtarry = spiltBySign(CLwtfjdz, "|");
                all.AddRange(wtarry);
            }
            if (all.Count > 0)
            {
                Response.Clear();
                Response.ContentType = "application/zip";
                Response.AddHeader("content-disposition", "filename=WTPHOTO.zip");
                using (ZipFile zip = new ZipFile(System.Text.Encoding.Default))//解決中文亂碼問題
                {
                    for (int i = 0; i < all.Count; i++)
                    {
                        zip.AddFile(ConfigurationManager.AppSettings["FilePath"].ToString()+ all[i], "");

                    }

                    zip.Save(Response.OutputStream);
                }

                Response.End();

            }

        }
