Redis，內存中的數據結構存儲，作為數據庫，緩存和消息代理。它支持的數據結構，如字符串、哈希表、列表、設置、排序設置範圍查詢，位圖，hyperloglogs和半徑查詢地理信息的索引。

使用內置的復制，Lua腳本，LRU逐出，磁盤上的持久性交易和不同等級，並且可以通過Redis的前哨和自動分區Redis集群高可用性。為了實現其出色的表現，Redis是工作在內存中的數據集

實現簡單的讀寫

一、新建一個控制臺項目

1、NuGet安裝

2、寫入

ConnectionMultiplexer con = RedisConnection.Connection;
IDatabase db = con.GetDatabase(1
 
);//不寫默認是連接到數據庫0
Student st = new Student { Age=12,Name="yuan",School="TaiKang"};
db.Set("student",st);

3、效果如圖

4、讀取

            ConnectionMultiplexer con = RedisConnection.Connection;
            IDatabase db = con.GetDatabase(1);//不寫默認是連接到數據庫0
            Student st = new Student();
            st = db.Get<Student>("
 
student");

二、輔助類

1、實體

    [Serializable]
    public class Student
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public int Age { get; set; }
        public string School { get; set; }
    }

2、鏈接數據庫（Redis）

public class RedisConnection
    {

        private
 
 static readonly Lazy<ConnectionMultiplexer> _connection = new Lazy<ConnectionMultiplexer>(() => ConnectionMultiplexer.Connect("localhost:6379"));

        public static ConnectionMultiplexer Connection { get { return _connection.Value; } }
    }

3、方法

public static class RedisExtension
    {
        public static TResult Get<TResult>(this IDatabase cache, string key)
        {
            return Deserialize<TResult>(cache.StringGet(key));
        }

        public static void Set<TIn>(this IDatabase cache, string key, TIn value)
        {
            cache.StringSet(key, Serialize(value));
        }

        static byte[] Serialize(object o)
        {
            if (o == null)
                return null;
            BinaryFormatter binaryFormatter = new BinaryFormatter();
            using (MemoryStream mStream = new MemoryStream())
            {
                binaryFormatter.Serialize(mStream, o);
                byte[] objectDataAsStream = mStream.ToArray();
                return objectDataAsStream;
            }
        }

        static TResult Deserialize<TResult>(byte[] stream)
        {
            if (stream == null)
                return default(TResult);
            BinaryFormatter formatter = new BinaryFormatter();
            using (MemoryStream memStream = new MemoryStream(stream))
            {
                TResult result = (TResult)formatter.Deserialize(memStream);
                return result;
            }
        }
    }
