StackExchange.Redis 封装

博主最近开始玩Redis啊~~

看了很多Redis的文章，感觉有点云里雾里的，之前看到是ServiceStack.Redis，看了一些大佬封装的Helper类，还是懵懵的QAQ

 

 

没办法啊只能硬着**上啊

开始着手写简单的Demo不同类型的存入、取出，之后写一些简单的封装，由简入繁嘛

用过ServiceStack.Redis后发现原来还有一个每小时只能调用 6000次的大坑。。卧槽ヾ(｡｀Д´｡) 

我哭了  你呢？太难了呀~~~

后来找到了StackExchange.Redis，园子里看完几篇文章之后 哇还这个比较友好。相见恨晚有木有！！！

 

下面进入正题   

我们先先看看两者的区别：

1. 已达到“6000 Redis请求每小时”的免费配额限制。 请参阅https://servicestack.net升级到商业许可证。。。相反，StackExchange.Redis没有限制，属于MIT许可证。
2. 性能方面的话ServiceStack.Redis高一点大概高出10%
3. StackExchange.Redis和ServiceStack.Redis大的区别是没有默认的连接池管理了。没有连接池自然有其利弊,最大的好处在于等待获取连接的等待时间没有了,也不会因为连接池里面的连接由于没有正确释放等原因导致无限等待而处于死锁状态。缺点在于一些低质量的代码可能导致服务器资源耗尽。不过提供连接池等阻塞和等待的手段是和作者的设计理念相违背的。StackExchange.Redis这里使用管道和多路复用的技术来实现减少连接,
4. ServiceStack.Redis 有限制，收费；StackExchange.Redis 开源，免费。

下面附上工具类：
