1 环境安装

下载地址：https://github.com/microsoftarchive/redis/releases

安装后可在services.msc中查看redis服务，如下图

 根据安装路径找到安装目录如下：

 找开redis.windows-service.conf文件可查看redis端口，用于连接redis。

 环境安装完毕。

2 编写工具类 RedisHelper.cs 

nuget需要安装包

Newtonsoft.Json;StackExchange.Redis;

代码如下

using Newtonsoft.Json;using StackExchange.Redis;using System;using System.Collections.Generic;using System.Configuration;using System.Linq;using System.Text;using System.Web;namespace XiHuiShouCargoList.Web.Utilities{ /// <summary> /// Redis读写帮助类 /// </summary> public class RedisHelper { private string RedisConnectionStr = ConfigurationManager.AppSettings["RedisConnectionStr"]; private ConnectionMultiplexer redis { get; set; } private IDatabase db { get; set; } public RedisHelper() { redis = ConnectionMultiplexer.Connect(RedisConnectionStr); db = redis.GetDatabase(); } #region string类型操作 /// <summary> /// set or update the value for string key /// </summary> /// <param name="key"></param> /// <param name="value"></param> /// <returns></returns> public bool SetStringValue(string key, string value) { return db.StringSet(key, value); } /// <summary> /// 保存单个key value /// </summary> /// <param name="key">Redis Key</param> /// <param name="value">保存的值</param> /// <param name="expiry">过期时间</param> /// <returns></returns> public bool SetStringKey(string key, string value, TimeSpan?

3 实践

 public class StoresController : ApiController { [WrapResult] public List<AiMaStoreDto> AiMa() { var redis = new RedisHelper(); List<AiMaStoreDto> stores = redis.GetStringKey<List<AiMaStoreDto>>("aimastores"); if (stores != null) return stores; stores = new List<AiMaStoreDto>();  redis.SetStringKey("aimastores", stores, TimeSpan.FromDays(1)); return stores; } }

4 命令行工具使用   双击 redis-cli.exe  打开

get [key] //按键查询，更多指令见redis文档
