C# 调用 java Web 服务：无法捕获 FaultException<CustomType>



我正在开发一个WCF应用程序，其中一个服务需要使用用Java开发的第三方web服务。第三方服务由政府提供，几乎不可能达到其代码/要求更改。

我从wsdl中将其添加为服务引用，该引用将自动生成。

方法调用似乎有效，但当我试图捕捉故障时，我无法获得第三方服务提供的自定义故障数据我在FaultException中只能得到"Fault occured which processing"(处理时发生故障)。(消息和原因都只能用这个设置。)

wsdl有一个自定义的错误类型，但看起来.NET无法将返回的SOAP响应映射到具有该类型的FaultException。因此，我的代码只得到一个带有通用消息和HasDetails=false的通用FaultException。

好吧，这对我们来说是一个问题，因为我们有义务向客户展示政府的网络服务返回了什么类型的故障。

你们以为我在捣鬼什么可以打败的东西吗？非常感谢您的任何建议，因为我已经很沮丧了。这是我代码中的一块：

try
{
//this is the 3rd party Java web service
EFaturaPortTypeClient efService = new EFaturaPortTypeClient();
//setting here the object to be sent to the 3rd party web service
var returnVal = efService.sendDocument(docRequest);
}
catch (FaultException<EFaturaFaultType> ex)
{
//need to get the "Reason" or "Detail" from the returned soap fault
//but cannot even get in here
}
catch (FaultException ex)
{
//this is where the debug goes
//tried below method, but retrieves nothing worthy
MessageFault mf = ex.CreateMessageFault();
throw new FaultException<EFaturaFaultType>(mf.GetDetail<EFaturaFaultType>());
}

下面是我嗅探到的错误的SOAP响应：

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<soap:Body>
<soap:Fault>
<soap:Code>
<soap:Value>soap:Receiver</soap:Value>
</soap:Code>
<soap:Reason>
<soap:Text xml:lang="en">2006:GECERSIZ ZARF ADI</soap:Text>
</soap:Reason>
<soap:Detail>
<ns3:EFaturaFault xmlns:ns3="http://gib.gov.tr/vedop3/eFatura" xmlns:xmime="http://www.w3.org/2005/05/xmlmime">
<code>2006</code>
<msg>GECERSIZ ZARF ADI</msg>
</ns3:EFaturaFault>
</soap:Detail>
</soap:Fault>
</soap:Body>
</soap:Envelope>

最后是第三方web服务的wsdl：

我实际上通过右键单击Visual Studio中解决方案资源管理器中的服务引用节点并选中"始终生成消息契约"框来解决了这个问题。不要问我是怎么到那里的。。。我只能在知道的情况下解释。生成的类和方法在那之后发生了更改，问题就消失了。尽管显然，它仍然没有针对通过生成的服务代理传递的空参数所导致的错误。

我希望它能有所帮助。

我认为您可能需要定义具有DataContract属性的EFaturaFaultType类，并使用DataMember属性标记任何可序列化成员。
