Redis缓存服务搭建及实现数据读写--转载

　　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

　　4、  测试

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", u);//设置缓存
u=redisHelper.Get("user");
Console.WriteLine(u.Name);
List list = new List()
{
new User(){Name="eric1",Id=1},
new User(){Name="eric2",Id=2}
};
redisHelper.Remove("list1");//删除缓存
redisHelper.AddList("list1", list);//添加缓存链表
redisHelper.AddEntityToList("list1", new User() { Name = "eric3",Id=3 });
list = redisHelper.GetList("list1").ToList();
Console.WriteLine(list.Count);
redisHelper.RemoveEntityFromList("list1", list[0]);
redisHelper.RemoveEntityFromList("list1", it => it.Id == 2);
list = redisHelper.GetList("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。
