实例介绍
【实例简介】
其中包含了Redis并发锁、Redis事务、Redis中List<T>/Hash<T>的读取、计数器、Redis队列、RedisTypedClient等示例
因为示例调用的是本机的Redis，所以需确保您的windows下已经安装了Redis，具体安装方式见 http://www.haolizi.net/example/view_8572.html
或者 更改Redis连接的ip地址为你的Redis服务器地址也可以

小贴士
感谢您为本站写下的评论，您的评论对其它用户来说具有重要的参考价值，所以请认真填写。
- 类似“顶”、“沙发”之类没有营养的文字，对勤劳贡献的楼主来说是令人沮丧的反馈信息。
- 相信您也不想看到一排文字/表情墙，所以请不要反馈意义不大的重复字符，也请尽量不要纯表情的回复。
- 提问之前请再仔细看一遍楼主的说明，或许是您遗漏了。
- 请勿到处挖坑绊人、招贴广告。既占空间让人厌烦，又没人会搭理，于人于己都无利。
