ServiceStack.Redis 之 IRedisTypedClient<第四篇>

IRedisTypedClient

　　IRedisTypedClient类相当于IRedicClient的强类型版，其方法与属性大多数与IRedisClient类似。

　　它支持在Redis中使用Linq查询的强大的类，它本身是一个泛型，IRedisClient的泛型方法As获得对象。

　　其方法原型如下：

　　　　IRedisTypedClient<T> As<T>();

　　1、IEntityStore<T>接口内容

　　其中IRedisTypedClient这个类实现了这个接口IEntityStore<T>，该接口要求提供的功能如下：

方法说明Delete根据实体删除一条记录DeleteAll全部删除DeleteById根据Id删除一条记录DeleteByIds根据输入的多个Id删除多条记录GetAll获取所有该类型的记录GetById根据Id获取一条记录GetByIds根据输入的多个Id获取多条记录Store根据传入的实体，添加一条记录StoreAll根据传入的实体集合，添加多条记录

　　Linq查询(针对于GetAll方法返回的IList<T>)示例：

        public ActionResult Index()        {            Person p1 = new Person() { Id = 1, Name = "刘备" };            Person p2 = new Person() { Id = 2, Name = "关羽" };            Person p3 = new Person() { Id = 3, Name = "张飞" };            Person p4 = new Person() { Id = 4, Name = "曹操" };            Person p5 = new Person() { Id = 5, Name = "典韦" };            Person p6 = new Person() { Id = 6, Name = "郭嘉" };            List<Person> ListPerson = new List<Person>() { p2,p3,p4,p5,p6 };            using (IRedisClient RClient = prcm.GetClient())            {                IRedisTypedClient<Person> IRPerson = RClient.As<Person>();                IRPerson.DeleteAll();                //------------------------------------------添加--------------------------------------------                //添加单条数据                IRPerson.Store(p1);                //添加多条数据                IRPerson.StoreAll(ListPerson);                //------------------------------------------查询--------------------------------------------                //Linq支持                Response.Write(IRPerson.GetAll().Where(m => m.Id == 1).First().Name);       //刘备                //注意，用IRedisTypedClient的对象IRPerson的Srore()添加的才能用IRPerson()方法读取                Response.Write(IRPerson.GetAll().First(m => m.Id == 2).Name);       //关羽　　　　　　　　　//------------------------------------------删除--------------------------------------------                IRPerson.Delete(p1);    //删除 刘备                Response.Write(IRPerson.GetAll().Count());      //5                IRPerson.DeleteById(2); //删除 关羽                Response.Write(IRPerson.GetAll().Count());      //4                IRPerson.DeleteByIds(new List<int> { 3,4 });    //删除张飞 曹操                Response.Write(IRPerson.GetAll().Count());      //2                IRPerson.DeleteAll();   //全部删除                Response.Write(IRPerson.GetAll().Count());      //0            }            return Content("");        }

　　另外，由于该接口并没有实现修改的方法，所以修改还得通过IRedisClient的实例：

        public ActionResult Index()        {            PooledRedisClientManager prcm = new PooledRedisClientManager(new List<string>() { "127.0.0.1" }, new List<string>() { "127.0.0.1" }, RedisConfig);            Person p1 = new Person() { Id = 1, Name = "刘备" };            Person p2 = new Person() { Id = 2, Name = "关羽" };            Person p3 = new Person() { Id = 3, Name = "张飞" };            Person p4 = new Person() { Id = 4, Name = "曹操" };            Person p5 = new Person() { Id = 5, Name = "典韦" };            Person p6 = new Person() { Id = 6, Name = "郭嘉" };            List<Person> ListPerson = new List<Person>() { p2,p3,p4,p5,p6 };            using (IRedisClient RClient = prcm.GetClient())            {                IRedisTypedClient<Person> IRPerson = RClient.As<Person>();                IRPerson.StoreAll(ListPerson);                //读取所有的Key                List<string> ListKeys = IRPerson.GetAllKeys();                      foreach (string key in ListKeys)                {                    Response.Write(key  + "<br/>");                }                //修改的话只能通过Key修改                //urn:person:3                //urn:person:4                //urn:person:5                //ids:Person                //urn:person:1                //urn:person:6                //urn:person:2                Person p7 = new Person() { Id = 8, Name = "撼地神牛" };                RClient.Set("urn:person:1", p7);                Response.Write(IRPerson.GetAll().First(m => m.Id == 8).Name);   //输出 撼地神牛            }            return Content("");        }
