Membercache缓存过期时间不同导致set成功，get失败怪异问题

xiaoweigogo 2014-03-26 10:42:04

最近项目中用到缓存，过期时间不同遇到set成功，get失败问题，请高手解答，小弟感激不尽，下面为过期时间不同所做的4个测试用例，key都是MD5加密的
测试1：



           string emailStep1TimeKey1 = Common.GetMd5Hash(account.UserId + email + "SafeEmailStep1");

            codeCache.Delete(emailStep1TimeKey1);

            DateTime dt1 = DateTime.Now.AddSeconds(350);

            bool b = codeCache.Set(emailStep1TimeKey1, DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"), dt1);

            object c = codeCache.Get(emailStep1TimeKey1);

测试1过期时间设为350秒，b为true，c为2014-03-26 10:19:53
测试2：



           string emailStep1TimeKey2 = Common.GetMd5Hash(account.UserId + email + "SafeEmailStep2");

            codeCache.Delete(emailStep1TimeKey2);

            DateTime dt2 = DateTime.Now.AddSeconds(339);

            bool b1 = codeCache.Set(emailStep1TimeKey2, DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"), dt2);

            object c1 = codeCache.Get(emailStep1TimeKey2);

测试2过期时间为339秒，b1为true，c1为null
测试3：



          string emailStep1TimeKey3 = Common.GetMd5Hash(account.UserId + email + "SafeEmailStep3");

            codeCache.Delete(emailStep1TimeKey3);

            DateTime dt3 = DateTime.Now.AddMinutes(10);

            bool b2 = codeCache.Set(emailStep1TimeKey3, DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"), dt3);

            object c2 = codeCache.Get(emailStep1TimeKey3);

测试3过期时间为10分钟，b2为true，c2为2014-03-26 10:20:46
测试4：



           string emailStep1TimeKey4 = Common.GetMd5Hash(account.UserId + email + "SafeEmailStep4");

            codeCache.Delete(emailStep1TimeKey4);

            DateTime dt4 = DateTime.Now.AddMinutes(5);

            bool b3 = codeCache.Set(emailStep1TimeKey4, DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"), dt4);

            object c3 = codeCache.Get(emailStep1TimeKey4);

测试4过期时间为5分钟，b3为true，c3为null
