是否可以在 serviceContract 中返回 System.Messaging.Message？

嘿嘿，我在 WCF 服务中使用 httpBinding / netTcpBinding，我试图用 WCF 替换一些 .Net 远程处理代码。这是我将 .Net 远程处理方法转换为 WCF 服务契约时的第一次测试。我按字面意思翻译了我的方法，旧代码使用 System.Messaging.Message 作为返回类型。

我的服务合同：

<OperationContract(Name:="ReceiveWithTimeOut")>
  <TransactionFlow(TransactionFlowOption.Allowed)>
  Function Receive(ByVal TimeOut As TimeSpan) As System.Messaging.Message

一切建立，服务上升，但是当我浏览我的服务时，出现以下错误：

System.InvalidOperationException：调用时引发异常 WSDL 导出扩展： System.ServiceModel.Description.DataContractSerializerOperationBehavior 合同： http://..../ServiceContracts/2012/V1:IReaderContract ----> System.Runtime.Serialization.InvalidDataContractException：类型 “System.Messaging.MessageQueue”无法序列化。

有什么方法可以返回 System.Messaging.Message 吗？

非常感谢。

亲切的问候。

Hej,
I am using the httpBinding / netTcpBinding in my WCF service, I am trying to replace some .Net remoting code with WCF. This was my first test when translating the methods of my .Net remoting to a WCF service contract. I translated my methods literally the old code uses System.Messaging.Message as return type.

My service contract:

<OperationContract(Name:="ReceiveWithTimeOut")>
  <TransactionFlow(TransactionFlowOption.Allowed)>
  Function Receive(ByVal TimeOut As TimeSpan) As System.Messaging.Message

Everyting builds, service goes up but when I surf to my service i got the following error:

System.InvalidOperationException: An exception was thrown in a call to
a WSDL export extension:
System.ServiceModel.Description.DataContractSerializerOperationBehavior
contract: http://..../ServiceContracts/2012/V1:IReaderContract ---->
System.Runtime.Serialization.InvalidDataContractException: Type
'System.Messaging.MessageQueue' cannot be serialized.

Is there any way to return a System.Messaging.Message?

Thank you very much.

Kind regards.
