.Net 5.0快速上手 Redis

1. Redis的安装地址:

https://files.cnblogs.com/files/lbjlbj/Redis3.7z

 

2.开启服务:

找到redis目录 打开cmd 输入redis-server.exe redis.windows.conf

看到如下图说明服务开启成功

 

3.基本操作:

再开一个控制台同样是redis目录下

redis-cli.exe -h 127.0.0.1 -p 6379

set myKey abc(myKey即Key,abc即value,set存)

get myKey(get读)

 

 4.Redis在C#中的实际用法:

注意:在使用redis 缓存时,必须先启动服务 redis-server.exe redis.windows.conf

dll文件:https://files.cnblogs.com/files/lbjlbj/dll.7z

可能会存在ConfigurationManager会报错,还需自行搜索添加引用,

奉上RedisHelper类

///

    {
        ///

        public RedisHelper() {
            _connection = ConnectionMultiplexer.Connect(_connectionStr);
            _db = GetDatabase();
        }

        ///

        {
            if (_connection != null && _connection.IsConnected)
            {
                return _connection;
            }
            lock (_lock)
            {
                if (_connection != null && _connection.IsConnected)
                {
                    return _connection;
                }

                if (_connection != null)
                {
                    _connection.Dispose();
                }
                _connection = ConnectionMultiplexer.Connect(_connectionStr);
            }

            return _connection;
        }


        /// 

        /// 获取数据库
        /// 
        /// 
        /// 
        public IDatabase GetDatabase(int? db = null)
        {
            return GetConnection().GetDatabase(db ?? -1);
        }

        /// 

        /// 设置缓存

        {
            if (data == null) return;
            var entryBytes = Serialize(data);
            var expiresIn = TimeSpan.FromMinutes(cacheDate);
            _db.StringSet(key, entryBytes, expiresIn);
        }

        public virtual T GetT(string key)
        {
            var rValue = _db.StringGet(key);
            if (!rValue.HasValue) return default(T);
            var result = Deserialize(rValue);
            return result;
        }
        ///

            if (serializedObject == null)
            {
                return default(T);
            }
            var json = Encoding.UTF8.GetString(serializedObject);
            return JsonConvert.DeserializeObject(json);
        }
        /// 

        /// 序列化
        ///

        private byte[] Serialize(object data)
        {
            var json = JsonConvert.SerializeObject(data);
            return Encoding.UTF8.GetBytes(json);
        }

        /// 

        /// 判断是否设置
        /// 
        /// 
        /// 
        public virtual bool IsSet(string key)
        {
            return _db.KeyExists(key);
        }
    }

AppConfig中配置:

 
    "RedisConnectionString" connectionString="localhost"/>
  

最后功能实现:

internal class Program
    {
        static void Main(string[] args)
        {
            string data = "a";
            new RedisHelper().SetCache("abc",data,10);
            Console.WriteLine("ok");
            Console.ReadKey();
        }
    }
