C# Redis实战(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：

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

  http://go.microsoft.com/fwlink/?LinkId=169433
  -->
<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：

 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：

 /// <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();
        }
