Windows安装Redis,C#简易交互
1.在网址【https://github.com/microsoftarchive/redis/releases】进行下载msi文件，下载完毕直接安装即可。
2.安装完毕后，在其安装目录【本人安装在F盘下】添加一个bat文件，内容为
redis-server.exe redis.windows.conf以便我们双击此批处理命令就能方便启动redis服务端
3.VS2019创建窗体应用程序，框架选用.net framework 4.7.2
4.简单设计一下界面
5.Nuget包安装【ServiceStack.Redis】库
6.添加一个类文件RedisUtil.cs
