[数据库].Net使用Redis详解之ServiceStack.Redis(七)


序言

本篇从.Net如何接入Reis开始,直至.Net对Redis的各种操作,为了方便学习与做为文档的查看,我做一遍注释展现,其中会对list的阻塞功能和事务的运用做二个案例,进行记录学习。

Redis官方推荐的.NET驱动类库为Service.Stack.Redis。然而网上对这个类库的中文文档不是很全面与合理,这篇文章主要就对这个类库做注释展现。不足遗漏之处还望见谅,海涵。

.Net使用Redis是非常方便与快捷与简单的,下面就让我展示下吧。

这里有必要说一下,如果你对Redis 中的基本对象数据类型还不了解,建议你看下我的前几篇Redis文章,保证要到病除。点击:我的Redis系列文章

项目中安装下载Service.Stack.Redis类库

右击项目->管理NuGet程序包->在联机中输入Reis就能出现这个类库,然后添加引入就行啦。

.Net链接Redis数据库,支持读写分离

1、配置文件
