StackExchange.Redis 之 SortedSet 类型示例

 1,增加操作

            RedisCacheHelper.Instance.ZSortadd("zsortkey", "A1", 5);
            RedisCacheHelper.Instance.ZSortadd("zsortkey", "B1", 6);
            RedisCacheHelper.Instance.ZSortadd("zsortkey", "C1", 2);
            RedisCacheHelper.Instance.ZSortadd("zsortkey", "D1", 1);
            RedisCacheHelper.Instance.ZSortadd("zsortkey", "1", 9);
            RedisCacheHelper.Instance.ZSortadd("zsortkey", "2", 8);
            RedisCacheHelper.Instance.ZSortadd("zsortkey", "3", 7);
            RedisCacheHelper.Instance.ZSortadd("zsortkey", "4", 1);

            RedisCacheHelper.Instance.ZSortIncr("zsortkey", "D1", 2);   //增加2
            RedisCacheHelper.Instance.ZSortDecr("zsortkey", "A1", 1);   //减去1

            //获取长度
            var getlength = RedisCacheHelper.Instance.SortedSetLength("zsortkey");
            Console.WriteLine(getlength);

            //移除某个元素
            var getok = RedisCacheHelper.Instance.ZSortedRemove("zsortkey", "1");
            Console.WriteLine(getok);

            //获取榜单某个元素的排名
            var getsort = RedisCacheHelper.Instance.ZSortedRank("zsortkey", "2");
            Console.WriteLine(getsort);

            //获取有序集合中的某个元素的值
            //扩展的有 
            //SortedSetRangeByRank   根据索引获取member值,默认是升序,可以获取指定索引内的member值
            //SortedSetRangeByScore：根据score获取member值,默认是升序,可以获取指定score开始和结束的member值,后面的skip和take用于分页
            //SortedSetRangeByValue：根据member获取member值,默认是升序,可以获取指定member开始和结束的值,后面的skip和take用于分页
            //SortedSetRangeByRankWithScores：获取member和score值，可以只返回 start-stop 这个索引排序内的值（默认升序），后面的skip和take用于分页

            var getvalue = RedisCacheHelper.Instance.ZSortedScore("zsortkey", "4");
            Console.WriteLine(getvalue);

这里附上Helper类
