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 = 1, Name = "a" }); db.ListRightPush("users", new User { ID = 2, Name = "b" }); db.ListRightPush("users", new User { ID = 3, Name = "c" }); Console.WriteLine(db.ListLength(CacheKeys.users)); User[] users = db.ListRange<User>(CacheKeys.users, 0, 2); foreach (var item in users) { Console.WriteLine("ID:{0},Name:{1}", item.ID, item.Name); } //Hash db.HashSet<User>(CacheKeys.HashKey, "1", new User { ID = 1 }); db.HashSet<User>(CacheKeys.HashKey, "2", new User { ID = 2 }); db.HashSet<User>(CacheKeys.HashKey, "3", new User { ID = 3 }); var user3 = db.HashGet<User>(CacheKeys.HashKey, "3"); Console.WriteLine("ID:{0},Name:{1}", user3.ID, user3.Name); //Set db.SetAdd<User>(CacheKeys.SetKey, new User { ID = 23, Name = "名称23" }); db.SetAdd<User>(CacheKeys.SetKey, new User { ID = 13, 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 = 1, Name = "name1" }, 1); db.SortedSetAdd(CacheKeys.SortedSetKey, new User { ID = 3, Name = "Log3" }, 5); db.SortedSetAdd(CacheKeys.SortedSetKey, new User { ID = 2, Name = "Log2" }, 2); db.SortedSetAdd(CacheKeys.SortedSetKey, new User { ID = -1, Name = "Log-1" }, -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); } } } } }
2.ServiceStack.Redis来调用
