1、安裝 RabbitMQ

首先，你需要安裝 RabbitMQ 服務(wù)器。你可以從官方網(wǎng)站下載 RabbitMQ，并按照官方文檔進(jìn)行安裝和配置。安裝完成后，確保 RabbitMQ 服務(wù)器正在運(yùn)行。sGk28資訊網(wǎng)——每日最新資訊28at.com

2、使用 RabbitMQ 基本功能

（1）發(fā)布和訂閱消息

RabbitMQ 的基本工作方式是生產(chǎn)者將消息發(fā)布到交換機(jī)，然后由消費(fèi)者從隊(duì)列中訂閱消息。以下是一個(gè)示例：sGk28資訊網(wǎng)——每日最新資訊28at.com

// 生產(chǎn)者var factory = new ConnectionFactory() { HostName = "localhost" };using (var connection = factory.CreateConnection())using (var channel = connection.CreateModel()){    channel.ExchangeDeclare(exchange: "logs", type: ExchangeType.Fanout);    var message = "Hello, RabbitMQ!";    var body = Encoding.UTF8.GetBytes(message);    channel.BasicPublish(exchange: "logs", routingKey: "", basicProperties: null, body: body);    Console.WriteLine("Sent: {0}", message);}// 消費(fèi)者var factory = new ConnectionFactory() { HostName = "localhost" };using (var connection = factory.CreateConnection())using (var channel = connection.CreateModel()){    channel.ExchangeDeclare(exchange: "logs", type: ExchangeType.Fanout);    var queueName = channel.QueueDeclare().QueueName;    channel.QueueBind(queue: queueName, exchange: "logs", routingKey: "");        var consumer = new EventingBasicConsumer(channel);    consumer.Received += (model, ea) =>    {        var body = ea.Body.ToArray();        var message = Encoding.UTF8.GetString(body);        Console.WriteLine("Received: {0}", message);    };    channel.BasicConsume(queue: queueName, autoAck: true, consumer: consumer);}

上述代碼中，生產(chǎn)者將消息發(fā)布到名為 "logs" 的交換機(jī)，而消費(fèi)者從該交換機(jī)創(chuàng)建一個(gè)隊(duì)列并訂閱消息。sGk28資訊網(wǎng)——每日最新資訊28at.com

（2）路由消息

RabbitMQ 允許你使用路由鍵將消息路由到特定隊(duì)列。以下是一個(gè)示例：sGk28資訊網(wǎng)——每日最新資訊28at.com

// 生產(chǎn)者var factory = new ConnectionFactory() { HostName = "localhost" };using (var connection = factory.CreateConnection())using (var channel = connection.CreateModel()){    channel.ExchangeDeclare(exchange: "direct_logs", type: ExchangeType.Direct);    var severity = "info";    var message = "Informational message.";    var body = Encoding.UTF8.GetBytes(message);    channel.BasicPublish(exchange: "direct_logs", routingKey: severity, basicProperties: null, body: body);    Console.WriteLine("Sent: [{0}] {1}", severity, message);}// 消費(fèi)者var factory = new ConnectionFactory() { HostName = "localhost" };using (var connection = factory.CreateConnection())using (var channel = connection.CreateModel()){    channel.ExchangeDeclare(exchange: "direct_logs", type: ExchangeType.Direct);    var queueName = channel.QueueDeclare().QueueName;    var severity = "info";    channel.QueueBind(queue: queueName, exchange: "direct_logs", routingKey: severity);    var consumer = new EventingBasicConsumer(channel);    consumer.Received += (model, ea) =>    {        var body = ea.Body.ToArray();        var message = Encoding.UTF8.GetString(body);        Console.WriteLine("Received: [{0}] {1}", severity, message);    };    channel.BasicConsume(queue: queueName, autoAck: true, consumer: consumer);}

在此示例中，消息被路由到具有特定路由鍵 "info" 的隊(duì)列。sGk28資訊網(wǎng)——每日最新資訊28at.com

（3）主題交換機(jī)

RabbitMQ 還支持主題交換機(jī)，允許你根據(jù)模式匹配消息的路由鍵進(jìn)行訂閱。以下是一個(gè)示例：sGk28資訊網(wǎng)——每日最新資訊28at.com

// 生產(chǎn)者var factory = new ConnectionFactory() { HostName = "localhost" };using (var connection = factory.CreateConnection())using (var channel = connection.CreateModel()){    channel.ExchangeDeclare(exchange: "topic_logs", type: ExchangeType.Topic);    var routingKey = "kern.critical";    var message = "Critical kernel error.";    var body = Encoding.UTF8.GetBytes(message);    channel.BasicPublish(exchange: "topic_logs", routingKey: routingKey, basicProperties: null, body: body);    Console.WriteLine("Sent: [{0}] {1}", routingKey, message);}// 消費(fèi)者var factory = new ConnectionFactory() { HostName = "localhost" };using (var connection = factory.CreateConnection())using (var channel = connection.CreateModel()){    channel.ExchangeDeclare(exchange: "topic_logs", type: ExchangeType.Topic);    var queueName = channel.QueueDeclare().QueueName;    var routingKey = "kern.*";    channel.QueueBind(queue: queueName, exchange: "topic_logs", routingKey: routingKey);    var consumer = new EventingBasicConsumer(channel);    consumer.Received += (model, ea) =>    {        var body = ea.Body.ToArray();        var message = Encoding.UTF8.GetString(body);        Console.WriteLine("Received: [{0}] {1}", routingKey, message);    };    channel.BasicConsume(queue: queueName, autoAck: true, consumer: consumer);}

在此示例中，消息被路由到匹配模式 "kern.*" 的隊(duì)列。sGk28資訊網(wǎng)——每日最新資訊28at.com

3、其他功能

RabbitMQ 還支持消息持久化、RPC（遠(yuǎn)程過程調(diào)用）、集群和安全等功能。你可以根據(jù)項(xiàng)目需求探索這些功能，并使用RabbitMQ的官方文檔和.NET客戶端庫來實(shí)現(xiàn)。sGk28資訊網(wǎng)——每日最新資訊28at.com

上述示例涵蓋了RabbitMQ的一些常見用例，希望可以幫助你入門RabbitMQ并在.NET應(yīng)用程序中使用它。sGk28資訊網(wǎng)——每日最新資訊28at.com
