我正在尝试创建一个 MSMQ WCF 服务，尽管我在运行代码时遇到了麻烦。尝试创建服务实例时失败。我安装了 MSMQ，并且可以确认有一个名为“ servicemodelsamples ”的私有创建

运行服务时，我收到以下错误；

无法启动服务。System.InvalidOperationException：打开队列时出错。确保 MSMQ 已安装并正在运行，队列存在并且具有适当的读取权限。内部异常可能包含附加信息。---> System.ServiceModel.MsmqException：打开队列时出错：无法识别的错误-1072824283（0xc00e0025）。无法从队列发送或接收消息。确保 MSMQ 已安装并正在运行。还要确保可以使用所需的访问模式和授权打开队列。

控制服务接口和实现。

[ServiceContract()]
public interface IControlService
{
   [OperationContract(IsOneWay = true)]
   void PricingAlert(int eventid, int marketid);
}

public class ControlService : IControlService
{
    public ControlService()
    { }

    public void PricingAlert(int eventid, int marketid)
    {
        Console.WriteLine("Acknowledged");
    }
}

Service1.cs 服务启动代码。 

protected override void OnStart(string[] args)
{
    Thread.Sleep(10000);
    string queueName = Settings.Default["queueName"].ToString();

    if (!MessageQueue.Exists(queueName))
        MessageQueue.Create(queueName, true);

    if (myServiceHost != null)
    {
        myServiceHost.Close();
    }
    myServiceHost = new ServiceHost(typeof(ControlService));
    myServiceHost.Open();    // *** Code Fails Here
}

应用程序配置；

      </setting>
    </ControlService.Properties.Settings>
  </applicationSettings>
</configuration>

有任何想法吗？我怀疑这可能是因为我将代码基于一个 winforms 应用程序的示例。

检查运行服务的用户。手动向队列添加权限。C:\Windows\System32\msmq\storage\lqs如果队列的权限被破坏，您应该使用记事本手动重置权限。
