无法加载DLL'mqrt.dll' [英] Unable to load DLL 'mqrt.dll'

问题描述

我开发了一个作为Windows服务托管的WCF服务，并公开了一个MSMQ端点。

我在SERVER1上有客户端应用程序，MSMQ和SERVER2上的WCF服务。

当SERVER1 / ClientApp尝试将消息推送到SERVER2 MSMQ时，我收到以下错误：

  System.TypeInitializationException：'System.ServiceModel.Channels.Msmq'的类型初始化程序抛出异常。 ---> System.DllNotFoundException：无法加载DLL'mqrt.dll'：找不到指定的模块。 （HRESULT的异常：0x8007007E）
在System.ServiceModel.Channels.UnsafeNativeMethods.MQGetPrivateComputerInformation（String computerName，IntPtr属性）
在System.ServiceModel.Channels.MsmqQueue.GetMsmqInformation（版本&版本，布尔& activeDirectoryEnabled ）

在FacilityManager.Service.NotificationsProcessorServiceReference.INotificationsProcessor.SendNewReactiveTaskNotifications（NewReactiveTaskDataContract newReactiveTaskDataContract）
  

SERVER1和SERVER2都运行Windows Server 2008 R2 Enterprise（6.1 SP1），并且都通过服务器管理器中的添加功能安装了MSMQ。

我明白DLL缺少（从错误中显而易见的），但我不知道我应该安装什么来获取它应该在哪里。

搜索在Windows资源管理器中显示该DLL存在于两台服务器上的以下目录中。

• C：\Windows\System32 C：\Windows \SysWOW64


• C：\Windows\winsxs\x86_microsoft-windows-msmq-runtime-core_31bf3856ad364e35_6。 1.7601.17514_none_5768e2ad17453bd6


• C：\Windows\winsxs\amd64_microsof t-windows-msmq-runtime-core_31bf3856ad364e35_6.1.7601.17514_none_b3877e30cfa2ad0c

任何帮助赞赏。

解决方案

我没有更聪明，但事情现在正在工作。

最后只是通过编写一个快速控制台应用程序来检查MSMQ是否安装在这两个服务器上，代码从这里获取...

https://stackoverflow.com/a/16104212/192999

我在两个控制台应用程序上运行Server1和Server2都返回，结果是True到IsMsmqInstalled。

然后我运行我的应用程序，无法加载DLLmqrt.dll错误是不再被提起。

我不知道调用 NativeMethods.LoadLibrary（Mqrt.dll）; 注册DLL或其他东西，但它肯定解决了我的问题。

我希望这将有助于未来！

I've developed a WCF Service which is hosted as a Windows Service and exposes a MSMQ endpoint.

I have the client app on SERVER1, and the MSMQ and WCF Service on SERVER2.

When the SERVER1/ClientApp attempts to push a message on to the SERVER2 MSMQ, I get the following errror:

    System.TypeInitializationException: The type initializer for 'System.ServiceModel.Channels.Msmq' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'mqrt.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

       at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation)
       at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

Exception rethrown at [7]: 
   at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg)

   at FacilityManager.Service.NotificationsProcessorServiceReference.INotificationsProcessor.SendNewReactiveTaskNotifications(NewReactiveTaskDataContract newReactiveTaskDataContract)

Both SERVER1 and SERVER2 are running Windows Server 2008 R2 Enterprise (6.1 SP1), and both have had MSMQ installed via the Add Features in Server Manager.

I understand that the DLL is missing (fairly obvious from the error!), but I've no idea what I should be installing to get the dll where it should be.

A search in Windows Explorer shows that the DLL is present in the following directories on both servers....

• C:\Windows\System32
• C:\Windows\SysWOW64
• C:\Windows\winsxs\x86_microsoft-windows-msmq-runtime-core_31bf3856ad364e35_6.1.7601.17514_none_5768e2ad17453bd6
• C:\Windows\winsxs\amd64_microsoft-windows-msmq-runtime-core_31bf3856ad364e35_6.1.7601.17514_none_b3877e30cfa2ad0c

Any help appreciated.

解决方案

I'm none the wiser but things are working now.

After hours on SO and Google, I ended up just checking that MSMQ was installed on both Servers by writing a quick console application with the code grabbed from here...

https://stackoverflow.com/a/16104212/192999

I ran the console app on both Server1 and Server2 and both came back with a result of True to IsMsmqInstalled.

I then ran my application and the "Unable to load DLL 'mqrt.dll'" error was no longer being raised.

I don't know if the call to NativeMethods.LoadLibrary("Mqrt.dll"); registered the DLL or something, but it certainly fixed my problem.

I hope this helps someone in the future!
