MVC连接Redis

Redis是一个内存数据库他非常的小想要启动Redis的话需要现下载以下

2.需要在需要使用命令行启动，首先定位到该目录，运行如下命令：

e:\Redis>redis-server.exe redis.conf

注意事项：打开服务后，当前端口不要关闭，关闭后服务也就关闭了。

接下来就该VS来连接和操作Redis

在添加下面类的时候需要下载以下引用

新创建一个类把以下代码粘上去

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using ServiceStack.Redis;

using ServiceStack.Text;

using ServiceStack.Redis.Generic;

public class RedisHelper:IDisposable

{

public RedisClient Redis = new RedisClient("169.254.54.11", 6379);

//缓存池

PooledRedisClientManager prcm = new PooledRedisClientManager();

//默认缓存过期时间单位秒

public int secondsTimeOut = 30 * 60;

new RedisClientManagerConfig

{

MaxReadPoolSize = readOnlyHosts.Length * 5,

AutoStart = true,

});// { RedisClientFactory = (IRedisClientFactory)RedisCacheClientFactory.Instance.CreateRedisClient("127.0.0.1", 6379) };

}

/// <summary>

#endregion

//释放资源

public void Dispose()

{

if (Redis != null)

{

Redis.Dispose();

Redis = null;

}

GC.Collect();

}

以上代码是帮助我们方便连接Redis

接下来就是控制器里面该写的内容了

这是视图显示的数据

当点击添加的时候让文本框显示出来
