对阿里云.net 客户端ons的进一步封装，ons是基于cpp dll的PInvoke调用封装，使用起来非常不方便，因此对ons进一步封装，方程序调用便. 示例代码:

1. 生产消息

   private static ProducerClient producerClient = new ProducerClient(AccessKeyId, AccessKeySecret, ProducerId);
   
   private static void Main(string[] args)
   {
       producerClient.Start();
   
       var stopWatch = new Stopwatch();
       stopWatch.Start();
   
       var taskList = new List<Task>();
       for (int threadIndex = 1; threadIndex <= ProducerThreadCount; threadIndex++)
       {
           // 生产消费
           var task = Task.Factory.StartNew(() => {
               for (int messageIndex = 1; messageIndex <= MessageCountPerThread; messageIndex++)
               {
                   string content = "线程ID=" + Thread.CurrentThread.ManagedThreadId + ", 我要测试rocketmq message";
                   //producerClient.SendMessage(ShardingKey, Topic, content, Tag);
                   producerClient.SendMessage(Topic, content, Tag);
   
                   Console.WriteLine(content);
               }
           }, TaskCreationOptions.LongRunning);
   
           taskList.Add(task);
       }
   
       Task.WaitAll(taskList.ToArray());
       stopWatch.Stop();
   
       // 一定要关闭，不然会有内存泄漏
       producerClient.Shutdown();
   
       Console.WriteLine("发送消息：{0}条， 使用时间{1}毫秒", MessageCountPerThread * ProducerThreadCount, stopWatch.ElapsedMilliseconds);
       Console.ReadLine();
   }
   

2. 消费消息

   private static PushConsumerClient consumerClient = new PushConsumerClient(AccessKeyId, AccessKeySecret, Topic, ConsumerId, SubExpression);
   
   private static int count = 0;
   
   private class MyMsgListener : DefaultMessageListener
   {
       public override ons.Action consume(Message message, ConsumeContext context)
       {
           Console.WriteLine("消息序号: {0}, 当前线程ID = {1}, 内容为： {2}", ++count, Thread.CurrentThread.ManagedThreadId, message.getBody());
           return ons.Action.CommitMessage;
       }
   }
   
   private static void Main(string[] args)
   {
       var listener = new MyMsgListener();
       consumerClient.setMessageListener(listener);
       consumerClient.Start();
   
       Console.ReadLine();
       consumerClient.Shutdown();
   }
