.net Redis缓存服务搭建及实现数据读写

发现博客园中好多大牛在介绍自己的开源项目是很少用到缓存，比如Memcached、Redis、mongodb等，今天得空抽时间把Redis缓存研究了一下，写下来总结一下，跟大家一起分享 一下。由于小弟水平有限又是第一次接触Redis，有些的不对的地方欢迎指出纠正。

1、  下载安装Redis

下载地址：https://github.com/MSOpenTech/Redis。

2、  安装Redis

     在下载的文件中找到bin并打开。

　　

• redis-server.exe：服务程序(目前我们只用到这一个)
• redis-check-dump.exe：本地数据库检查
•  redis-check-aof.exe：更新日志检查
•  redis-benchmark.exe：性能测试，用以模拟同时由N个客户端发送M个 SETs/GETs 查询 (类似于 Apache 的ab 工具).

Redis有很多配置参数，这里就不介绍了，有兴趣的朋友可以到网上查查。

双击redis-server.exe或者在命令窗口中输入D:\redis-2.6\redis-server.exe即可启动Redis服务。

 

 注意端口号：Port：6379 在我们的程序中会用到该端口号。

3、  数据读、写、删测试，并实现list存数。

首先引用下面四个DLL文件

               }                Redis.Expire(key, secondsTimeOut);            }                        return Redis.Add<T>(key, t);        }        /// <summary>        /// 获取        /// </summary>        /// <typeparam name="T"></typeparam>        /// <param name="key"></param>        /// <returns></returns>        public T Get<T>(string key)        {            return Redis.Get<T>(key);

4、  测试

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Threading;namespace RedisStudy{    public class User    {        public string Name { get; set; }        public int Id { get; set; }    }    class Program    {        static RedisHelper redisHelper = new RedisHelper(true);                static void Main(string[] args)        {            User u = new User() { Name = "eric1", Id = 1 };            redisHelper.Set<User>("user", u);//设置缓存            u=redisHelper.Get<User>("user");            Console.WriteLine(u.Name);                        List<User> list = new List<User>()            {                new User(){Name="eric1",Id=1},                 new User(){Name="eric2",Id=2}            };                       redisHelper.Remove("list1");//删除缓存            redisHelper.AddList<User>("list1", list);//添加缓存链表            redisHelper.AddEntityToList<User>("list1", new User() { Name = "eric3",Id=3 });            list = redisHelper.GetList<User>("list1").ToList();            Console.WriteLine(list.Count);            redisHelper.RemoveEntityFromList<User>("list1", list[0]);            redisHelper.RemoveEntityFromList<User>("list1", it => it.Id == 2);            list = redisHelper.GetList<User>("list1").ToList();            Console.WriteLine(list.Count);            redisHelper.Dispose();            Console.ReadLine();                     }    }}

 

整篇文章写的比较仓促，很多基本点都没有说明，有不懂的请百度一下。
