Cache缓存

               

  设置缓存：

ArrayList myarray = new ArrayList();

                 myarray.Add(mes);           
                HttpRuntime.Cache.Add(phone, myarray, null, DateTime.Now.AddMinutes(5),

                    TimeSpan.Zero, System.Web.Caching.CacheItemPriority.High, null);

缓存取值：

               ArrayList dt = (ArrayList)HttpRuntime.Cache[tel];
                if (Lanjia.Rule.Security.MD5Encryption(code) == dt[0].ToString())
