下载安装 https://github.com/MicrosoftArchive/redis/releases/tag/win-3.2.100

项目 nuget  添加 StackExchange.Redis

添加 RedisHelper 类

配置连接字符串 <add name="RedisConnectionString" connectionString="127.0.0.1:6379,password=123456"/>

配置密码  Program Files\Redis\redis.windows-service.conf  修改文件  requirepass 123456  默认没有密码
