使用 StackExchange.Redis 開發 Redis 的 Lua Scripting 程式，只要簡單的透過 Database 物件的 ScriptEvaluateAsync 方法，將 Lua script 及所需的 keys 與 values 帶入即可。 using StackExchange.Redis; ... var configuration = GetConfiguration(); using (var conn = ConnectionMultiplexer.Connect(configuration)) { var db = conn.GetDatabase(); var script = GetScript(); var keys = GetKeys(); var values = GetValues(); var result = db.ScriptEvaluate(script, keys, values); ... } ... 像是下面這邊筆者用 Lua script 實作了類似 Redis 的 MSET 命令，可同時設定三組 Key/Value，寫起來會像下面這樣： using System; using StackExchange.Redis; namespace ConsoleApplication4 { class Program { static void Main(string[] args) { var configuration = "localhost:6379"; using (var conn = ConnectionMultiplexer.

使用 StackExchange.Redis 開發 Redis 的 Pub/Sub 程式，需先調用 GetSubscriber 方法取得 Subscriber 物件，再透過該 Subscriber 物件去設定事件訂閱以及發佈訂閱即可。 像是下面這邊筆者訂閱了 MemberOnLine 的事件，當事件發生時會將上線資訊顯示在主控台，然後發佈 LarryNung 上線的事件給訂閱者： using System; using StackExchange.Redis; namespace ConsoleApplication4 { class Program { static void Main(string[] args) { var configuration = "localhost:6379"; using (var conn = ConnectionMultiplexer.Connect(configuration)) { var sub = conn.GetSubscriber(); var key = "MemberOnLine"; sub.Subscribe(key, (c, v) => { Console.WriteLine("{0} Online...", v); }); sub.PublishAsync(key, "LarryNung", CommandFlags.FireAndForget); } } } } 運行結果如下： {% img /images/posts/PubSubInStackExchange.

要使用 StackeExchange.Redis 取得 Server 的資訊，或是運行 Server 的命令。要先調用 GetServer 方法取得 Server 物件，再透過該 Server 成員屬性或方法去操作即可。 像是下面這邊筆者遍巡了每台 Server，並將其相關的資訊顯示到主控台： using System; using StackExchange.Redis; namespace ConsoleApplication4 { class Program { static void Main(string[] args) { var configuration = "localhost:6379"; using (var conn = ConnectionMultiplexer.Connect(configuration)) { var endPoints = conn.GetEndPoints(); foreach (var endPoint in endPoints) { var server = conn.GetServer(endPoint); Console.WriteLine("Server: {0}", server.Multiplexer); Console.WriteLine("IsSlave: {0}", server.IsSlave); Console.WriteLine("AllowSlaveWrites: {0}", server.AllowSlaveWrites); Console.WriteLine("ServerType: {0}", server.ServerType); Console.WriteLine("Version: {0}", server.Version); Console.WriteLine("ServerTime: {0}", server.

欲連線至 Redis，需先設定 Configutaion，在 StackExchange.Redis 提供兩種設定方式，一種是用 ConfigurationOptions 物件直接宣告設定： using StackExchange.Redis; ... var configuration = new ConfigurationOptions() { EndPoints = { {"localhost", 6379}, {"localhost", 6380} }, Password = "LarryNung" }; using (var conn = ConnectionMultiplexer.Connect(configuration)) { ... } ... 一種是透過字串的方式設定： using StackExchange.Redis; ... var configuration = "localhost:6379,localhost:6380,password=LarryNung"; using (var conn = ConnectionMultiplexer.Connect(configuration)) { ... } ... 如果不清楚有哪些可供設定，可參閱下表： {% img /images/posts/ConfigurationInStackExchange.Redis/1.png %} {% img /images/posts/ConfigurationInStackExchange.Redis/2.png %}

StackExchange.Redis 是 StackExchange 提供的 redis client 實作。 該套件具有以下特點： High performance multiplexed design, allowing for efficient use of shared connections from multiple calling threads Abstraction over redis node configuration: the client can silently negotiate multiple redis servers for robustness and availability Convenient access to the full redis feature-set Full dual programming model both synchronous and asynchronous usage, without requiring “sync over async” usage of the TPL Support for redis “cluster” 使用上需先透過 NuGet 套件管理視窗安裝套件，他有提供兩種套件，一種是不含強命名簽章的套件 StackExchange.
