关于Redis的安装以及多实例运用请看我另外的博客，本文主要叫这么在代码中去实现对Redis数据库的基本数据操作

1.首先在nuget管理工具装redis包  

2.在 appsettings.json里配置redis链接字符串

 3.创建Redis工具类，方便对数据库操作，类名RedisHelper

public class RedisHelper
    {
        private IDatabase db { get; set; }
        public RedisHelper()
        {
            IConfiguration configuration = new ConfigurationBuilder()
                .SetBasePath(Environment.CurrentDirectory)
                .AddJsonFile("appsettings.json", true, true)
                .AddInMemoryCollection()
                .Build();
            string sqlConnectionString = configuration["RedisConfig:ConnectionString"];
            db = ConnectionMultiplexer.Connect(sqlConnectionString).GetDatabase();
        }

        /// <summary>
        /// 增加/修改
        /// </summary>
        /// <param name="key"></param>
        /// <param name="value"></param>
        /// <returns></returns>
        public bool SetValue(string key, string value)
        {
            return db.StringSet(key, value);
        }

        /// <summary>
        /// 查询
        /// </summary>
        /// <param name="key"></param>
        /// <returns></returns>
        public string GetValue(string key)
        {
            return db.StringGet(key);
        }

        /// <summary>
        /// 删除
        /// </summary>
        /// <param name="key"></param>
        /// <returns></returns>
        public bool DeleteKey(string key)
        {
            return db.KeyDelete(key);
        }
    }

4.实操

到这里就是我对Redis的基本操作，希望对初学者有帮助
