RocketMQ C#的消息发送与接收

RocketMQ是一个开源的分布式消息中间件，支持高可靠、高性能、可伸缩的消息传递。在C#中使用RocketMQ发送和接收消息需要使用RocketMQ的客户端库。

以下是使用RocketMQ C#客户端库发送和接收消息的基本示例：

发送消息：

using System; using RocketMQ.Client; using RocketMQ.Client.Producer;  class Program {     static void Main(string[] args)     {         DefaultMQProducer producer = new DefaultMQProducer("ProducerGroup");         producer.NamesrvAddr = "127.0.0.1:9876";          try         {             producer.Start();              Message msg = new Message("TopicTest", "TagA", "Hello RocketMQ".GetBytes());             SendResult sendResult = producer.Send(msg);             Console.WriteLine($"SendResult: {sendResult}");         }         catch (Exception ex)         {             Console.WriteLine($"Exception: {ex.Message}");         }         finally         {             producer.Shutdown();         }     } } 

接收消息：

using System; using RocketMQ.Client; using RocketMQ.Client.Consumer;  class Program {     static void Main(string[] args)     {         DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("ConsumerGroup");         consumer.NamesrvAddr = "127.0.0.1:9876";         consumer.Subscribe("TopicTest", "TagA");          consumer.RegisterMessageListener((MessageListenerConcurrently)(msgs) =>         {             foreach (var msg in msgs)             {                 Console.WriteLine($"Received message: {msg.Body}");             }              return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;         });          try         {             consumer.Start();             Console.WriteLine("Consumer started.");         }         catch (Exception ex)         {             Console.WriteLine($"Exception: {ex.Message}");         }          Console.ReadLine();     } } 

以上示例分别演示了如何在C#中使用RocketMQ发送和接收消息。在实陵使用RocketMQ C#客户端库时，需要引入RocketMQ.Client库，并根据具体的业务需求配置Producer和Consumer的相关参数。
