redis 初步认识四（redis锁，防并发）

using System;

namespace ConsoleAppRedis

    class Program
    {
        static void Main(string[] args)
        {
            //第一种，无登录密码
            //var rds = new CSRedis.CSRedisClient("127.0.0.1:6379");
            //rds.Set("test1", "123123", 60);
            //var str = rds.Get("test1");
            //Console.WriteLine(str);

            //第二种
            //RedisHelper.Initialization(rds);
            //RedisHelper.Set("aaaa", 11111);
            //var str1 = RedisHelper.Get("aaaa");
            //Console.WriteLine(str1);

            //第三种，有登录密码
            var rds2 = new CSRedis.CSRedisClient("127.0.0.1:6379,password=123456,defaultDatabase=13,poolsize=50,ssl=false,writeBuffer=10240,prefix=key前辍");

            var str3 = rds2.Get("test1");
