.NET使用Redis基本操作实战

需要的DLL

using ServiceStack.Common.Extensions;
using ServiceStack.Redis;
using ServiceStack.Redis.Generic;
using ServiceStack.Text;
using ServiceStack.Redis.Support;

声明一个客户端对象：

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("additemtolist", x));
注：也可直接使用AddRangeToList方法将一组数据装入如：

Redis.AddRangeToList("addarrangetolist", storeMembers);

2. 获取数据：

var members = Redis.GetAllItemsFromList("additemtolist");
members.ForEach(s => Response.Write("<br/>additemtolist :"+ s));

3. 获取指定索引位置数据：

var item = Redis.GetItemFromList("addarrangetolist", 2);

4. 移除：

var list = Redis.Lists["addarrangetolist"];
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：

publicclass UserInfo
{
publiclong Id { set; get; }
publicstring UserName { get; set; }
publicint 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
Redis.Set<byte[]>("userinfolist_serialize", ser.Serialize(userinfoList));
List<UserInfo> userList = ser.Deserialize(Redis.Get<byte[]>("userinfolist_serialize")) as List<UserInfo>;

三.存储表格对象，比如：

using (var redisUsers = Redis.GetTypedClient<UserInfo>())
{
redisUsers.Store(new UserInfo { Id = redisUsers.GetNextSequence(), UserName ="daizhj", Age =12 });
redisUsers.Store(new UserInfo { Id = redisUsers.GetNextSequence(), UserName ="daizhenjun", Age =13 });

var allUsers = redisUsers.GetAll();//就像操作ado对象一样，可以进行CRUD等操作
allUsers.ForEach(s => Response.Write("<br/>user :"+ s.UserName +" age:"+ s.Age));
}

四.使用客户端链接池模式提升链接速度：

publicstatic PooledRedisClientManager CreateManager(string[] readWriteHosts, string[] readOnlyHosts)
{
//支持读写分离，均衡负载
returnnew PooledRedisClientManager(readWriteHosts, readOnlyHosts, new RedisClientManagerConfig
{
MaxWritePoolSize =5,//“写”链接池链接数
MaxReadPoolSize =5,//“写”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(newstring[] { "127.0.0.1:6379" }, newstring[] { "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");
}
