[StackExchange]Redis 的几种类型的操作（string，hash，lists，set,sorted set）

概述

通过网页进行测试，页面有录入和读取按钮，如下图:

String

   /// <summary>
        /// 插入字符串
        /// </summary>
        /// <returns></returns>
        public string Inserttest()
        {
            //操作数据库0
            var db = connect.GetDatabase(0);
            return db.StringSet("test", Request.Params["value"]).ToString();

        }
          /// <summary>
        /// 插入hash
        /// </summary>
        /// <returns></returns>
        public string Inserthtest()
        {
            //操作数据库0
            var db = connect.GetDatabase(0);
            return db.HashSet("htest", Guid.NewGuid().ToString(), Request.Params["value"]).ToString();
        }

Hash

   /// <summary>
        /// 插入list
        /// </summary>
        /// <returns></returns>
        public string Insertltest()
        {
            //操作数据库0
            var db = connect.GetDatabase(0);
            return db.ListLeftPush("ltest", Request.Params["value"]).ToString();

        }
          /// <summary>
        /// 获取hash
        /// </summary>
        /// <returns></returns>
        public string Gethtest()
        {
            //操作数据库0
            var db = connect.GetDatabase(0);
            var result = db.HashGetAll("htest");
            return string.Join("|", result.Select(item => item.Name + ":" + item.Value).ToList<string>());
        }

Lists

  /// <summary>
        /// 插入list
        /// </summary>
        /// <returns></returns>
        public string Insertltest()
        {
            //操作数据库0
            var db = connect.GetDatabase(0);
            return db.ListLeftPush("ltest", Request.Params["value"]).ToString();

        }
          /// <summary>
        /// 获取list
        /// </summary>
        /// <returns></returns>
        public string Getltest()
        {
            //操作数据库0
            var db = connect.GetDatabase(0);
            System.Text.StringBuilder result = new System.Text.StringBuilder("本次读取将清空List：");
            for (var i = db.ListLength("ltest"); i > 0; i--)
            {
                result.Append(db.ListLeftPop("ltest") + ",");
            }
            return result.ToString();
        }

Set

  /// <summary>
        /// 插入set
        /// </summary>
        /// <returns></returns>
        public string Insertstest()
        {
            //操作数据库0
            var db = connect.GetDatabase(0);
            return db.SetAdd("stest", Request.Params["value"]).ToString();
        }
           /// <summary>
        /// 获取set
        /// </summary>
        /// <returns></returns>
        public string Getstest()
        {
            //操作数据库0
            var db = connect.GetDatabase(0);
            var result = db.SetMembers("stest");
            return string.Join(",", result);
        }

Sorted Set

/// <summary>
        /// 插入排序set
        /// </summary>
        /// <returns></returns>
        public string Insertsstest()
        {
            //操作数据库0
            var db = connect.GetDatabase(0);
            return db.SortedSetAdd("sstest", Request.Params["value"], (new Random()).Next(0, 100)).ToString();
        }
          /// <summary>
        /// 获取排序set
        /// </summary>
        /// <returns></returns>
        public string Getsstest()
        {
            //操作数据库0
            var db = connect.GetDatabase(0);
            var result = db.SortedSetScan("sstest");
            return string.Join("|", result.Select(item => item.Element + ":" + item.Score).ToList<string>());
        }

总结

整体来说本demo只对几个类型做了简单的插入与读取操作，在操作过程中发现了Lists是采用的入队列出队列的方式进行操作了，和C#中的List不同，不能遍历数据而不改变数据集（目前了解的是这样，不知是否有其他方式遍历）。

运行结果
