.NET下添加Redis

Redis 是一个开源的使用ANSI C 语言编写、支持网络、可基于内存亦可持久化的日志型、Key-Value 数据库。Redis的出现，很大程度补偿了memcached这类key/value存储的不足，在部 分场合可以对关系数据库起到很好的补充作用。

本文主要讲述的是如何使用C#语言来进行Redis分布式缓存的程序编写。首先，需要从github下载最新的32/64位安装，解压后根据自己机器的实际情况选择32位或者64位，例如：我机器是64位win7，于是将64bit下所有文件拷贝到D盘根目录下新建文件夹redis中,或者直接下载Redis服务(可以将此服务设置为windows系统服务，下载Redis服务安装软件，安装即可。)，我个人比较喜欢这个。

第一步，从Nuget下载Redis，我用的是ServiceStack.Redis,新版本是5.0.2，我怕不稳定，下载了5.0.0

添加后自动引用Dll

第二步，在配置文件添加redis的相关配置

 <configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
     <section name="RedisConfig" type="GTA.FTRTP.Common.Redis.RedisConfigInfo, GTA.FTRTP.Common" />

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

第三步，添加一些基本的读写操作

  public class RedisConfigInfo: ConfigurationSection
    {
        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;
        }
        /// <summary>
        /// 可写的Redis链接地址
        /// </summary>
        [ConfigurationProperty("WriteServerList", IsRequired = false)]
        public string WriteServerList
        {
            get
            {
                return (string)base["WriteServerList"];
            }
            set
            {
                base["WriteServerList"] = value;
            }
        }


        /// <summary>
        /// 可读的Redis链接地址
        /// </summary>
        [ConfigurationProperty("ReadServerList", IsRequired = false)]
        public string ReadServerList
        {
            get
            {
                return (string)base["ReadServerList"];
            }
            set
            {
                base["ReadServerList"] = value;
            }
        }
           …………
}

 public class RedisManager
    {
        /// <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();
        }

    }

第四步，在controller直接引用贴出部分代码

  var redis = RedisManager.GetClient();
            var redsiClass = redis.Get<Class>("All");//判断是否已经缓存
            if (redsiClass != null)
            {
                model = redsiClass;
            }
            else 
            {
                var entity = db.Class.FirstOrDefault(e => e.ClassId == StringKeys.UniversityId);

                var getClassList = ClassRepository.GetClassListByParentId(StringKeys.UniversityId).OrderBy(a => a.ClassId);
                var firstOrDefault = getClassList.FirstOrDefault();
                model.CollageId = firstOrDefault != null ? firstOrDefault.ClassId : 0;

              
                redis.Set<Class>("All", model);//没有则进行添加

                db.Dispose();
            }

第五步，如果是有新的数据生成应该删除缓存存数据到数据库的

  public void Remove(string value)
        {
            var redis = RedisManager.GetClient();
            redis.Remove(value);
         
        }

以上就是redis简单的使用。
