Net中应用 Redis 扩展类

GIt地址:https://gitee.com/loogn/stackexchange-redis-typedextensions

1.stackexchange 类调用

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks; using StackExchange.Redis; namespace RedisTest
{ public class User
{
public int ID { get; set; }
public string Name { get; set; }
} class Program
{
static void Main(string[] args)
{
using (var conn = ConnectionMultiplexer.Connect("localhost:6379,password=Aa111111."))
{
var db = conn.GetDatabase();
//list
db.ListRightPush("users", new User { ID = , Name = "a" });
db.ListRightPush("users", new User { ID = , Name = "b" });
db.ListRightPush("users", new User { ID = , Name = "c" }); Console.WriteLine(db.ListLength(CacheKeys.users));
User[] users = db.ListRange<User>(CacheKeys.users, , );
foreach (var item in users)
{
Console.WriteLine("ID:{0},Name:{1}", item.ID, item.Name);
} //Hash
db.HashSet<User>(CacheKeys.HashKey, "", new User { ID = });
db.HashSet<User>(CacheKeys.HashKey, "", new User { ID = });
db.HashSet<User>(CacheKeys.HashKey, "", new User { ID = });
var user3 = db.HashGet<User>(CacheKeys.HashKey, "");
Console.WriteLine("ID:{0},Name:{1}", user3.ID, user3.Name); //Set
db.SetAdd<User>(CacheKeys.SetKey, new User { ID = , Name = "名称23" });
db.SetAdd<User>(CacheKeys.SetKey, new User { ID = , Name = "名称13" });
var userRandom = db.SetRandomMember<User>(CacheKeys.SetKey);
Console.WriteLine("ID:{0},Name:{1}", userRandom.ID, userRandom.Name); //SortedSet
db.SortedSetAdd(CacheKeys.SortedSetKey, new User { ID = , Name = "name1" }, );
db.SortedSetAdd(CacheKeys.SortedSetKey, new User { ID = , Name = "Log3" }, );
db.SortedSetAdd(CacheKeys.SortedSetKey, new User { ID = , Name = "Log2" }, );
db.SortedSetAdd(CacheKeys.SortedSetKey, new User { ID = -, Name = "Log-1" }, -);
var userArr = db.SortedSetRangeByScoreWithScores<User>(CacheKeys.SortedSetKey);
foreach (var item in userArr)
{
Console.WriteLine("ID:{0},Name:{1},score:{2}", item.Element.ID, item.Element.Name, item.Score);
}
}
}
}
}
