未将消息添加到我的 MSMQ

Question

我正在尝试第一次运行 MSMQ 服务。

我从 MSDN 复制了一个示例，我正在尝试让它工作。

一切正常，没有错误。然而，当我去检查我的 MSMQ 时，没有可用/添加的消息。

我使用了Trace工具SvcTraceViewe.exe，没有报错。

这是我在类 DLL 中定义的服务：

public class MotionSaver : IMotionSaver
{
    [OperationBehavior]
    public void MotionFrame(byte[] data)
    {
        // DO I NEED TO PUT ANTHING IN HERE??
    }
}

[ServiceContract]
public interface IMotionSaver
{
    //IsOneWay=true denotes that there will no return message from the server to the client.
    [OperationContract(IsOneWay = true)]
    void MotionFrame(byte[] data);
}

这是调用上述 DLL 的我的服务器主机：

static void Main(string[] args)
{
    try
    {
        using (ServiceHost host = new ServiceHost(typeof(MotionSaver)))
        {
            //Path of the Queue. Here we are creating a private queue with the name VishalQ 
            //where all our message would be stored, if server is unavialable.
            string queueName = ConfigurationManager.AppSettings["queueName"];
            //Checking whether the queue exists or not.
            if (!MessageQueue.Exists(queueName))
            {
                //If the queue doesnot exists it will create a queue with the name VishalQ
                //the second parameter false denotes that the queue would be a non transaction queue. If you want that your queue to be 
                //transaction then make the second parameter to true.
                MessageQueue.Create(queueName, true);
            }
            //finally opening the host to server the clients.
            host.Open();
            Console.WriteLine("Server is up and running on port 32578");
            Console.WriteLine("Press any key to exit");
            Console.ReadKey();
        }
    }
    catch  (Exception ex)
    {
        Console.WriteLine(ex.ToString());
        Console.ReadKey();
    }
}

这是我在宿主应用程序中的 app.config 设置：

<configuration>
  <appSettings>
    <add key="queueName" value=".\private$\MotionSaverTest4" />
  </appSettings>

  <system.diagnostics>
    <trace autoflush="true" />

              type="System.Diagnostics.XmlWriterTraceListener"
              initializeData= "SdrConfigExample.e2e" />
        </listeners>
      </source>
    </sources>
  </system.diagnostics>

这是调用服务的客户端应用：

static void Main(string[] args)
{
    wsMotionQ.MotionSaverClient ws = new MotionSaverClient();
    ws.MotionFrame(new byte[] { 1 });

    Console.WriteLine("All Wishes sent successfully");
    Console.ReadLine();
}

这是我的客户端 app.config：

<configuration>
    <system.serviceModel>
        <bindings>
            <netMsmqBinding>
                <binding name="motionQ">
                    <security mode="None" />
                </binding>
            </netMsmqBinding>
        </bindings>
        <client>
            <endpoint address="net.msmq://localhost/private/MotionSaverTest4"
                binding="netMsmqBinding" bindingConfiguration="motionQ" contract="wsMotionQ.IMotionSaver"
                name="motionQ">
                <identity>
                    <dns value="localhost" />
                </identity>
            </endpoint>
        </client>
    </system.serviceModel>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2"/>
  </startup>
</configuration>

我已检查我的消息队列已创建。

1)。消息如何添加到队列中？我的服务中的空方法有什么意义？ 2）。为什么我的消息没有被添加？

谢谢

注意

将代码更改为：

[OperationBehavior]
public void MotionFrame(byte[] jpegData)
{
    using (Message msg = new Message())
    {
        msg.BodyStream = new MemoryStream(jpegData);
        msgQMissedData.Send(msg);
    }
}

Answer 1

您只是在创建队列，而不是向/从它发送/接收消息。
