Redis菜鸟教程（三）StackExchange.Redis的

Redis官网推荐的客户端，如下图

Redis官网推荐的客户端

官网主要推荐的是# ServiceStack.Redis与StackExchange.Redis，不过 ServiceStack.Redis是收费的。再此主要说明
Redis 客户端：StackExchange.Redis的使用

安装StackExchange.Redis
PM> Install-Package StackExchange.Redis

保存一个List集合到Redis中的Hash表中

     static void Main(string[] args)
        {
            RedisHelper redisHelper = new RedisHelper("127.0.0.1:6379,password=food");
         
            #region Hash
            List<RightsDto> list = new List<RightsDto>()
          {
              new RightsDto(){ ID=10001,Code="aaa",Name="bbb",Explanation="ccc",Remark="ddd"},
              new RightsDto(){ ID=10002,Code="aaa",Name="bbb",Explanation="ccc",Remark="ddd"}

          };
            redisHelper.HashSet<RightsDto>("RightsTable", list, R => 
            {
                return R.ID.ToString();
            });
          
            #endregion

            Console.ReadKey();
        }

Redis软件监控结果

读取刚才保存到Redis中的List集合
var RsultList= redisHelper.HashGetAll< RightsDto>("RightsTable");
