protected RedisClient Redis = new RedisClient("127.0.0.1", 6379);//redis服务IP和端口一 .基本KEY/VALUE键值对操作：
1. 添加/获取:
List<string> storeMembers = new List<string>();storeMembers.ForEach(x => Redis.AddItemToList("test", x));//注：也可直接使用AddRangeToList方法将一组数据装入如：Redis.AddRangeToList("testt", storeMembers);2. 获取数据
var members = Redis.GetAllItemsFromList("test");members.ForEach(s => Response.Write("<br/>test :" + s));3. 获取指定索引位置数据
var item = Redis.GetItemFromList("test", 2);4. 移除：
var list = Redis.Lists["test"]; ?list.Clear();//清空 ?list.Remove("two");//移除指定键值 ?list.RemoveAt(2);//移除指定索引位置数据二.存储对象：
[Serializable]public class UserInfo ???{ ???????public long Id { set; get; } ???????public string UserName { get; set; } ???????public int Age { get; set; } ???}1.通常方式（底层使用json序列化）：
Redis.Set<UserInfo>("userinfo", new UserInfo() { UserName = "李四", Age = 45 }); ?UserInfo userinfo = Redis.Get<UserInfo>("userinfo");注：当然上面方式也适合于基本类型，如：
Redis.Set<int>("my_age", 12);//或Redis.Set("my_age", 12);int age = Redis.Get<int>("my_age");2.object序列化方式存储：
var ser = new ObjectSerializer(); ???//位于namespace ServiceStack.Redis.Support; ?bool result = Redis.Set<byte[]>("userinfo", ser.Serialize(new UserInfo() { UserName = "张三", Age = 12 })); ?UserInfo userinfo = ser.Deserialize(Redis.Get<byte[]>("userinfo")) as UserInfo; ?//也支持列表 ?List<UserInfo> userinfoList = new List<UserInfo>(); ?userinfoList.Add(new UserInfo() { UserName = "pool_daizhj", Age = 1 }); ?userinfoList.Add(new UserInfo() { UserName = "pool_daizhj1", Age = 2 }); ?Redis.Set<byte[]>("userinfolist_serialize", ser.Serialize(userinfoList)); ?List<UserInfo> userList = ser.Deserialize(Redis.Get<byte[]>("userinfolist_serialize")) as List<UserInfo>;需要说明的是在测试过程中发现JSON序列化的效率要比object序列化高一些。
三.存储表格对象，比如：
using (var redisUsers = Redis.As<UserInfo>()) ?{ ?????redisUsers.Store(new UserInfo { Id = redisUsers.GetNextSequence(), UserName = "test1", Age = 22 }); ?????redisUsers.Store(new UserInfo { Id = redisUsers.GetNextSequence(), UserName = "test2", Age = 23 }); ?????var allUsers = redisUsers.GetAll();//就像操作ado对象一样，可以进行CRUD等操作 ?}四.使用客户端链接池模式提升链接速度：
public static PooledRedisClientManager CreateManager(string[] readWriteHosts, string[] readOnlyHosts) ?{ ??????//支持读写分离，均衡负载 ??????return new PooledRedisClientManager(readWriteHosts, readOnlyHosts, new RedisClientManagerConfig ??????{ ??????????MaxWritePoolSize = 5,//“写”链接池链接数 ??????????MaxReadPoolSize = 5,//“读”链接池链接数 ??????????AutoStart = true, ??????}); ???????????}声明链接池对象（这里只使用一个redis服务端）：
PooledRedisClientManager prcm = CreateManager(new string[] { "127.0.0.1:6379" }, new string[] { "127.0.0.1:6379" }); ??List<UserInfo> userinfoList = new List<UserInfo>(); ?userinfoList.Add(new UserInfo() { UserName = "pool_daizhj", Age = 1 }); ?userinfoList.Add(new UserInfo() { UserName = "pool_daizhj1", Age = 2 });从池中获取一个链接：
using (IRedisClient Redis = prcm.GetClient()) ?{ ????????????????????Redis.Set("userinfolist", userinfoList); ??????List<UserInfo> userList = Redis.Get<List<UserInfo>>("userinfolist"); ?}注：
如只想使用长链接而不是链接池的话，可以直接将下面对象用static方式声明即可：
protected static RedisClient Redis = new RedisClient("127.0.0.1", 6379);这样在redis服务端显示只有一个客户链接
