从 WCF 客户端使用非 wcf SOAP 错误（定义了 SOAP 错误）

我有一个从 WCF 客户端调用的非 WCF 服务器，我需要访问已注册的肥皂故障，以防服务器抛出它（它包含我需要用户的反馈）。我使用了来自的例子如何从 WCF 客户端访问 SOAP 1.1 错误详细信息（无错误契约） https://stackoverflow.com/q/2134658/518649但这是一个痛苦，因为我确实在 wsdl 中定义了错误契约，至少按照 SOAP 规范，并且错误包含错误代码和错误字符串。

<wsdl:types>
    <schema elementFormDefault="qualified" targetNamespace="http://www.cisco.com/BTS10200/i01" xmlns="http://www.w3.org/2001/XMLSchema">
        ...
        <complexType name="BtsSoapException">
            <sequence>
                <element name="error_code" type="xsd:int"/>
                <element name="error_string" nillable="true" type="xsd:string"/>
            </sequence>
        </complexType>
        <element name="fault" type="impl:BtsSoapException"/>
...

<wsdl:message name="BtsSoapException">
    <wsdl:part element="impl:fault" name="fault"/>
</wsdl:message>
...

<wsdl:portType name="Bts10200Operations">
    <wsdl:operation name="login">
        <wsdl:input message="impl:loginRequest" name="loginRequest"/>
        <wsdl:output message="impl:loginResponse" name="loginResponse"/>
        <wsdl:fault message="impl:BtsSoapException" name="BtsSoapException"/>
    </wsdl:operation>
...

服务导入可以正确识别所有这些并生成正确的代码结构：

[System.Runtime.Serialization.DataContractAttribute(Name="BtsSoapException", Namespace="http://www.cisco.com/BTS10200/i01")]
[System.SerializableAttribute()]
public partial class BtsSoapException : object ...

....

[System.ServiceModel.ServiceContractAttribute(Namespace="http://www.cisco.com/BTS10200/i01", ConfigurationName="CiscoBTSService.Bts10200Operations")]
public interface Bts10200Operations {
    [System.ServiceModel.OperationContractAttribute(Action="", ReplyAction="*")]
    [System.ServiceModel.FaultContractAttribute(typeof(TestCiscoBTS.CiscoBTSService.BtsSoapException), Action="", Name="fault")]
    TestCiscoBTS.CiscoBTSService.loginResponse login(TestCiscoBTS.CiscoBTSService.loginRequest request);
...

当我打电话给login()对于无效帐户，我确实根据 wsdl 得到了正确的响应：

<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <soapenv:Body>
        <soapenv:Fault>
            <faultcode>soapenv:Server.generalException</faultcode>
            <faultstring></faultstring>
            <detail>
                <ns1:fault xmlns:ns1="http://www.cisco.com/BTS10200/i01">
                    <error_code>401</error_code>
                    <error_string xsi:type="xsd:string">java.lang.Exception: No user profile defined in the database for fakeuser</error_string>
                </ns1:fault>
                <ns2:exceptionName xmlns:ns2="http://xml.apache.org/axis/">com.sswitch.oam.soap.intf.BtsSoapException</ns2:exceptionName>
                <ns3:stackTrace xmlns:ns3="http://xml.apache.org/axis/">
    at com.sswitch.oam.soap.impl.UserAuth.validateUser(UserAuth.java:63)
    ...

The FaultExcpetion确实会火，但它是空白的（Message= "") 并且我没有看到任何公开 BtsSoapException 实例的属性。就像它根本没有被反序列化一样（尽管 wcf 知道它需要做的一切）。我究竟做错了什么？我如何让 WCF 给我FaultException<BtsSoapException>?

您是否尝试过执行如下代码所示的操作，您需要捕获包含您正在查找的信息的特定肥皂故障合约。中的信息这篇 MSDN 文章 http://msdn.microsoft.com/en-us/library/system.servicemodel.faultcontractattribute.aspx应该有帮助。

var proxy = new WhatEverYourServiceProxyClassIsNamed();
try
{
    //your call logic here

    proxy.Close();
}
catch (FaultException<BtsSoapException> bse)
{
    //Get the info you're looking for in the strongly typed soap fault:

    proxy.Abort();
}
catch (FaultException fe)
{
    //Do something appropriate for a non-typed soap fault

    proxy.Abort();
}
finally
{
    if ((ICommunicationObject)proxy).State != CommunicationState.Closed)
        proxy.Abort();
}
