Redis锁的实现

[ren8179]

该实现依赖于CSRedisCore包

        private bool LockOrderNo(string lockKey, int delyInterval = 120)
        {
            if (RedisHelper.SetNx(lockKey, DateTime.Now.AddSeconds(delyInterval).ToFileTimeUtc()))
            {
                RedisHelper.Expire(lockKey, delyInterval);
                return true;
            }
            else
            {
