C# 通过ServiceStack 操作Redis——String类型的使用及示例

1.引用Nuget包 ServiceStack.Redis

我这里就用别人已经封装好的Reids操作类，来演示，并附上一些说明

RedisConfigInfo--redis配置文件信息

    /// <summary>
    /// redis配置文件信息
    /// 也可以放到配置文件去
    /// </summary>
    public sealed class RedisConfigInfo
    {
        /// <summary>
        /// 可写的Redis链接地址
        /// format:ip1,ip2
        ///
        /// 默认6379端口
        /// </summary>
        public string WriteServerList = "127.0.0.1:6379";
        /// <summary>
        /// 可读的Redis链接地址
        /// format:ip1,ip2
        /// </summary>
        public string ReadServerList = "127.0.0.1:6379";
        /// <summary>
        /// 最大写链接数
        /// </summary>
        public int MaxWritePoolSize = 60;
        /// <summary>
        /// 最大读链接数
        /// </summary>
        public int MaxReadPoolSize = 60;
        /// <summary>
        /// 本地缓存到期时间，单位:秒
        /// </summary>
        public int LocalCacheTime = 180;
        /// <summary>
        /// 自动重启
        /// </summary>
        public bool AutoStart = true;
        /// <summary>
        /// 是否记录日志,该设置仅用于排查redis运行时出现的问题,
        /// 如redis工作正常,请关闭该项
        /// </summary>
        public bool RecordeLog = false;
    }

RedisManager --Redis管理中心   创建Redis链接

    /// <summary>
    /// Redis管理中心   创建Redis链接
    /// </summary>
    public class RedisManager
    {
        /// <summary>
        /// redis配置文件信息
        /// </summary>
        private static RedisConfigInfo RedisConfigInfo = new RedisConfigInfo();

        /// <summary>
        /// Redis客户端池化管理
        /// </summary>
        private static PooledRedisClientManager prcManager;

        /// <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[] WriteServerConStr = RedisConfigInfo.WriteServerList.Split(',');
            string[] ReadServerConStr = RedisConfigInfo.ReadServerList.Split(',');
            prcManager = new PooledRedisClientManager(ReadServerConStr, WriteServerConStr,
                             new RedisClientManagerConfig
                             {
                                 MaxWritePoolSize = RedisConfigInfo.MaxWritePoolSize,
                                 MaxReadPoolSize = RedisConfigInfo.MaxReadPoolSize,
                                 AutoStart = RedisConfigInfo.AutoStart,
                             });
        }

        /// <summary>
        /// 客户端缓存操作对象
        /// </summary>
        public static IRedisClient GetClient()
        {
            return prcManager.GetClient();
        }
    }

RedisBase-- 是redis操作的基类，继承自IDisposable接口，主要用于释放内存

/// <summary>
    /// RedisBase类，是redis操作的基类，继承自IDisposable接口，主要用于释放内存
    /// </summary>
    public abstract class RedisBase : IDisposable
    {
        public IRedisClient iClient { get; private set; }
        /// <summary>
        /// 构造时完成链接的打开
        /// </summary>
        public RedisBase()
        {
            iClient = RedisManager.GetClient();
        }

        //public static IRedisClient iClient { get; private set; }
        //static RedisBase()
        //{
        //    iClient = RedisManager.GetClient();
        //}

        private bool _disposed = false;
        protected virtual void Dispose(bool disposing)
        {
            if (!this._disposed)
            {
                if (disposing)
                {
                    iClient.Dispose();
                    iClient = null;
                }
            }
            this._disposed = true;
        }
        public void Dispose()
        {
            Dispose(true);
            GC.SuppressFinalize(this);
        }

        public void Transcation()
        {
            using (IRedisTransaction irt = this.iClient.CreateTransaction())
            {
                try
                {
                    irt.QueueCommand(r => r.Set("key", 20));
                    irt.QueueCommand(r => r.Increment("key", 1));
                    irt.Commit(); // 提交事务
                }
                catch (Exception ex)
                {
                    irt.Rollback();
                    throw ex;
                }
            }
        }

        /// <summary>
        /// 清除全部数据 请小心
        /// </summary>
        public virtual void FlushAll()
        {
            iClient.FlushAll();
        }

        /// <summary>
        /// 保存数据DB文件到硬盘
        /// </summary>
        public void Save()
        {
            iClient.Save();//阻塞式save
        }

        /// <summary>
        /// 异步保存数据DB文件到硬盘
        /// </summary>
        public void SaveAsync()
        {
            iClient.SaveAsync();//异步save
        }
    }

nuget包是外国人写的，在国内并没有完整的中文文档，也没有专门的人来翻译、封装它，所以上面的代码方法不是很全，还有很多api方法需要自己去官网找然后自己封装。

在这里，上面的封装我就放一边，还是给大家演示ServiceStack原生的API如何使用

2. string 类型的使用

                //1.存入键值对
                bool a = client.Set("key_name", "value_11");
                //2. 根据key获取值
                string data1= client.GetValue("key_name");
                //3. 在原有的value上进行追加
                long data2 = client.AppendToValue("key_name", "value_11");
               // 4.获取值的长度
                var data3=client.GetStringCount("key_name");
                //5. 数值自增/减，返回自增、自减后的值
                client.Set("小明分数", 100);
                //自增20，可以自增负值
               var data4= client.IncrementValueBy("小明分数", 20);
                //自减50
                var data5 = client.DecrementValueBy("小明分数", 50);
                //6. 插入实体和读取实体
                UserInfo userInfo = new UserInfo() { Id = 3, Age = 50, Name = "zxl", Pwd = "123456" };
                client.Set("UserInfo_Id_3", userInfo);
                UserInfo data6 = client.Get<UserInfo>("UserInfo_Id_3");
                //7. 一次性添加多个key-value集合
                Dictionary<string, string> dic = new Dictionary<string, string>() {
                    { "101", Guid.NewGuid().ToString("N")},
                    { "102", Guid.NewGuid().ToString("N")},
                    { "103", Guid.NewGuid().ToString("N")},
                    { "104", Guid.NewGuid().ToString("N")},
                    { "105", Guid.NewGuid().ToString("N")},
                    { "106", Guid.NewGuid().ToString("N")}
                };
                client.SetAll(dic);
                //8.获取多个key的 value值集合
                List<string> keys = new List<string>(){ "101", "103", "105" };
                List<string> data8=  client.GetValues(keys);

                //9. 重命名key
                client.Rename("106", "1066");
                //10. 设置key的过期时间(30秒后自动销毁)
                bool b2= client.Expire("102", 30);

                //11. 删除单个key
                bool d1 = client.Remove("101");//删除成功，返回true
                bool d2 = client.Remove("ffff"); //删除不存在的数据，返回false

//12. 删除多个key
                IEnumerable<string> delete_keys = new List<string> { "101", "103", "105" };
                client.RemoveAll(delete_keys);

//13.清除全部数据 请小心
client.FlushAll();
