c#对第三方缓存redis的操作（三）

三、程序配置

在C# Redis实战(二)中我们安装好了Redis的系统服务，此时Redis服务已经运行。

现在我们需要让我们的程序能正确读取到Redis服务地址等一系列的配置信息，首先，需要在Web.config文件中添加如下信息：

[html] view
plaincopy





<?xml version="1.0" encoding="utf-8"?>

<!--

-->

<configuration>

<configSections>

<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->

<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

<section name="RedisConfig" type="RedisDemo.RedisConfigInfo, RedisDemo"/>

</configSections>

<RedisConfig WriteServerList="127.0.0.1:6379" ReadServerList="127.0.0.1:6379" MaxWritePoolSize="60"

MaxReadPoolSize="60" AutoStart="true" LocalCacheTime="180" RecordeLog="false">

</RedisConfig>

<connectionStrings>

<add name="DefaultConnection" providerName="System.Data.SqlClient" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-RedisDemo-20131125110945;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-RedisDemo-20131125110945.mdf" />

</connectionStrings>



</configuration>

有了以上信息还不够，还需要用C#代码来读取并且操作，获取Redis配置的程序如下：

[csharp] view
plaincopy





public static RedisConfigInfo GetConfig()

{

RedisConfigInfo section = (RedisConfigInfo)ConfigurationManager.GetSection("RedisConfig");

return section;

}



public static RedisConfigInfo GetConfig(string sectionName)

{

RedisConfigInfo section = (RedisConfigInfo)ConfigurationManager.GetSection("RedisConfig");

if (section == null)

throw new ConfigurationErrorsException("Section " + sectionName + " is not found.");

return section;

}

Redis管理类代码：

[csharp] view
plaincopy





/// <summary>

/// redis配置文件信息

/// </summary>

private static RedisConfigInfo redisConfigInfo = RedisConfigInfo.GetConfig();



private static PooledRedisClientManager prcm;



/// <summary>

/// 静态构造方法，初始化链接池管理对象

/// </summary>

static RedisManager()

{

CreateManager();

}





/// <summary>

/// 创建链接池管理对象

/// </summary>

private static void CreateManager()

{

string[] writeServerList = SplitString(redisConfigInfo.WriteServerList, ",");

string[] readServerList = SplitString(redisConfigInfo.ReadServerList, ",");



prcm = new PooledRedisClientManager(readServerList, writeServerList,

new RedisClientManagerConfig

{

MaxWritePoolSize = redisConfigInfo.MaxWritePoolSize,

MaxReadPoolSize = redisConfigInfo.MaxReadPoolSize,

AutoStart = redisConfigInfo.AutoStart,

});

}



private static string[] SplitString(string strSource, string split)

{

return strSource.Split(split.ToArray());

}



/// <summary>

/// 客户端缓存操作对象

/// </summary>

public static IRedisClient GetClient()

{

if (prcm == null)

CreateManager();



return prcm.GetClient();

}
