为什么使用redis
Redis适合所有数据in-momory的场景,虽然Redis也提供持久化功能,但实际更多的是一个disk-backed的功能,跟传统意义上的持久化有比较大的差别,那么可能大家就会有疑问,似乎Redis更像一个加强版的Memcached.
上面描述说的过于泛了,很多初次接触的码农可能不明白怎么回事;其实简单来说:如果业务中需要高性能、分布式、集群等场景的时候,redis就可以派上用场大显身手了!
redis简介
REmote DIctionary Server(Redis) 是一个由Salvatore Sanfilippo写的key-value存储系统。
Redis是一个开源的使用ANSI C语言编写、遵守BSD协议、支持网络、可基于内存亦可持久化的日志型、Key-Value数据库,并提供多种语言的API。
它通常被称为数据结构服务器,因为值(value)可以是 字符串(String), 哈希(Map), 列表(list), 集合(sets) 和 有序集合(sorted sets)等类型。
常用结构
.net连接redis
StackExchange.Redis是.NET语言中一个高性能的通用redis客户端,一般都基于这个驱动来实现具体的操作业务

StackExchange.Redis封装
和ado.net一样,StackExchange.Redis只是一个provider,码农们直接用起来会很麻烦,不光要去理解它里面很多概念,还要根据不同的场景写不能的代码,所以在实际业务中,本人封装了一个drive.redis
github地址:https://github.com/yswenli/RedisDrive/tree/master/Wenli.Drive.Redis
Wenli.Drive.Redis的使用
本人封装的这个drive.redis是基于现有相关项目完善而成的,主要目的就是为码农们方便开展自已的业务,无需去关心中间相当部内容;使用可以参考md文件中的描述:
RedisDrive
RedisDrive这是一个.net 的redis集成驱动,支持单实例、云集群、哨兵等模式的数据操作,支持keys等命令
本驱动基于stackexcnage.redis完成,在此基础上强化使用的简洁性、可靠性
wenli.Drive.Redis使用方法:
1.添加wenli.Drive.Redis引用
2.添加stackexcnage.redis nuget包引用
3.添加Wenli.Drive.Redis、log4net配置节点,添加RedisClient appsettings
app.config(web.config)配置如下: <?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="RedisConfig" type="Wenli.Drive.Redis.RedisConfig, Wenli.Drive.Redis" />
