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

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");
