OK，进入正题

在本篇开始之前，再来一个小插曲，这个小插曲是关于Redis命令的，关于更详细的Redis命令，大家可参考Redis中文网。

1、window命令下连接redis【cmd打开命令黑框】

C:Userschenwolong>redis-cli
127.0.0.1:6379> ping
PONG

2、如何设置redis密码

127.0.0.1:6379> config get requirepass
1) "requirepass"
2) ""
127.0.0.1:6379> config get requirepass
1) "requirepass"
2) ""
127.0.0.1:6379> config set requirepass 123456
OK
127.0.0.1:6379> ping
(error) NOAUTH Authentication required.
127.0.0.1:6379>

上面指令的意思是：获取当前redis密码，设置redis密码为：123456，在此连接redis，结果redis返回给我们：NOAUTH Authentication required.未授权。

因此，设置密码后，我们就需要输入密码进行登录了。

127.0.0.1:6379> auth 123456
OK
127.0.0.1:6379> ping
PONG
127.0.0.1:6379>

上述为输入密码，并登录。

然后我们就可以使用redis中文网的命令了，例如：Keys *

127.0.0.1:6379> keys *
1) "set01"
2) "rds_set01"
127.0.0.1:6379>

获取Redis的路径，获取Redis持久化dump.Rdb文件所在地址

127.0.0.1:6379> config get dir
1) "dir"
2) "C:\Program Files\Redis"
127.0.0.1:6379>

关于redis设置密码这个话题，个人认为非必要，是不需要设置的，因为连接起来比较麻烦，而且违反了redis运行快的理念。

那么，我们再次把密码设置为空，如下：

127.0.0.1:6379> config set requirepass ""
OK
127.0.0.1:6379> ping
PONG
127.0.0.1:6379>

演示下清空数据的方法：

127.0.0.1:6379> flushall
OK
127.0.0.1:6379> flushdb
OK
127.0.0.1:6379>

注意：flushall 是清空所有数据库的键值对，flushdb 是清空当前数据库的键值对，关于这两个指令，大家慎用，用不好，或误用，就可能被批斗哦，甚至辞退。

最后，我们获取redis配置文件设置的最大连接数

127.0.0.1:6379> CONFIG GET maxclients
1) "maxclients"
2) "10000"
127.0.0.1:6379>

获取当前连接的客户端数量：

connected_clients:1
client_recent_max_input_buffer:2
client_recent_max_output_buffer:0
blocked_clients:0
127.0.0.1:6379>

如果不进行手动释放，redis 会根据设置的 timeout，清理空闲的链接

OK 小插曲就到此位置

通过参考博客及下载下的源码，发现代码里没有针对无序集合Set的封装，因此，鄙人不自量力，针对Set无序集合进行封装。

首先，原代码下载：https://download.csdn.net/download/wolongbb/15810789

 

因为是代码类的博文，因此，直接上代码了

3、客户端调用

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using StackExchange.Redis;
using Newtonsoft.Json;
using RedisHelpers;

namespace RedisConsole
{
    class Program
    {
        static void Main(string[] args)
        {
            RedisHelper redis = new RedisHelper();
            redis.SetAdd<string>("set01", "01");
            redis.SetAdd<string>("set01", "02");
            redis.SetAdd<string>("set01", "03");
            redis.SetAdd<string>("set01", "04");
            redis.SetAdd<string>("set01", "04");
            var setmodel = new SetModel1()
            {
                Id = 1,
                Name = "陈卧龙",
                Address = "江苏苏州",
                age = 30
            };
            redis.SetAdd<SetModel1>("set01", setmodel);

            //
            var bol = redis.SetContains("set01", setmodel);
            if (bol)
            {
                Console.WriteLine("set01集合中包含对象setmodel");
            }
            var Sets = redis.SetMembers("set01");
            foreach(var tiem in Sets)
            {
                Console.WriteLine(tiem);
            }
            Console.ReadLine();
        }
    }

    class SetModel1
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Address { get; set; }
        public int age { get; set; }
    }
}

4、配置文件配置：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <connectionStrings>
        <add name="RedisExchangeHosts" connectionString="127.0.0.1:6379,allowadmin=true"/>
    </connectionStrings>
    <appSettings>
        <add key="redisKey" value="rds_"/>
    </appSettings>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1"/>
    </startup>
</configuration>
