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("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
