Redis在.net中的应用学习

在Redis的官网（http://redis.io/clients#c）上可以看到支持Redis C#的客户端。

redis的网络连接方式和传统的rdbms相似，一种是长连接，一种是连接池，此处使用长连接进行连接。

目前redis官方版本不支持.net直接进行连接，需要使用一些开源类库。目前最流行的就是ServiceStack.redis，可以通过https://github.com/ServiceStack/ServiceStack.Redis下载最新版本。

下载完成解压，在ServiceStack.Redis-masteruild eleaseMonoDevelop目录下看到ServiceStack.Redis.zip文件，这个就是需要引入到.net项目中的4个dll文件。

测试时发现四个文件版本比较旧，可以通过编译redis源码，生成最新的dll文件。

打开VS2013，创建一个控制台应用程序,写了一些简单的Redis操作

    {
        private static RedisClient redis = new RedisClient("192.168.32.216", 6379, "anny");
        static void Main(string[] args)
        {
            //单个字符串写入
            redis.SetValue("age", "20");
            //读取指定key的字符串
            redis.GetValue("age");

            //存储数字
            redis.Set<int>("int_age", 30);
            int age = redis.Get<int>("int_age");
            Console.WriteLine("int_age={0}", age);
    
            //将字符串列表写入Redis List
            List<string> colourList = new List<string>{"red","pink","green","blue","black","white"};
            colourList.ForEach(item => redis.AddItemToList("colourList", item));

            //读取Redis List内容
            List<string> colourList1 = redis.GetAllItemsFromList("colourList");
            colourList1.ForEach(item => Console.Write(item + " "));

            //存储实体对象，在Redis中以json格式存储
            UserInfo user = new UserInfo(){Id=1, Name="Mark", Age=32, City="ShangHai" };
            redis.Set<UserInfo>("user_1", user);
            UserInfo user1 = redis.Get<UserInfo>("user_1");
            Console.WriteLine("id={0},name={1},age={2},city={3}", user1.Id, user1.Name, user1.Age, user1.City);

            //object序列化方式
            var ser = new ObjectSerializer();
            redis.Set<byte[]>("user1", ser.Serialize(user));
            UserInfo user11 = ser.Deserialize(redis.Get<byte[]>("user1")) as UserInfo;
            Console.WriteLine("id={0},name={1},age={2},city={3}", user1.Id, user1.Name, user1.Age, user1.City);

            //存储对象列表到redis中
            List<UserInfo> userList = new List<UserInfo>{
                new UserInfo{Id=2, Name="Jack", Age=27, City="beijing" },
                new UserInfo{Id=3, Name="Tom", Age=25, City="XiaMen" }
            };

            redis.Set<byte[]>("userlist", ser.Serialize(userList));
            List<UserInfo> userList1 = ser.Deserialize(redis.Get<byte[]>("userlist")) as List<UserInfo>;
            userList1.ForEach(i =>
            {
                Console.WriteLine("id={0},name={1},age={2},city={3}", i.Id, i.Name, i.Age, i.City);
            });

            
            Console.Read();
        }

        [Serializable]
        class UserInfo
        {
            public int Id { get; set; }
            public string Name { get; set; }
            public int Age { get; set; }

            public string City { get; set; }
        }
    }
}
