1. Redis的安装地址:

https://files.cnblogs.com/files/lbjlbj/Redis3.7z

2.开启服务:

找到redis目录 打开cmd 输入redis-server.exe redis.windows.conf

看到如下图说明服务开启成功

3.基本操作:

再开一个控制台同样是redis目录下

redis-cli.exe -h 127.0.0.1 -p 6379

set myKey abc(myKey即Key,abc即value,set存)

get myKey(get读)

4.Redis在C#中的实际用法:

注意:在使用redis 缓存时,必须先启动服务 redis-server.exe redis.windows.conf

dll文件:https://files.cnblogs.com/files/lbjlbj/dll.7z

可能会存在ConfigurationManager会报错,还需自行搜索添加引用,

奉上RedisHelper类

AppConfig中配置:

最后功能实现:

internal class Program
{
static void Main(string[] args)
{
string data = "a";
new RedisHelper().SetCache("abc",data,10);
Console.WriteLine("ok");
Console.ReadKey();
}
}
