Question

我正在尝试创建一个MSMQ WCF服务，尽管我遇到了运行代码的麻烦。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：有打开队列时出错。确保已安装并运行MSMQ，队列存在并具有可读取的适当授权。该内部异常可能包含其他信息。 ---＆GT; System.ServiceModel.MsmqException：打开时出错 queue：无法识别的错误-1072824283（0xc00e0025）。消息不能从队列中发送或接收。确保已安装MSMQ 运行。还要确保队列可以打开所需的访问模式和授权。

控制服务接口和实施。

[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;

有什么想法吗？我怀疑它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。手动将权限添加到队列中。如果队列中断了权限，则应使用记事本在C:\Windows\System32\msmq\storage\lqs中手动重置权限。
