我正在使用C＃/ WCF（.NET 3.5 SP1）并尝试访问通过Apache / PHP托管的SOAP服务。首先生成WSDL，然后构建服务以符合WSDL。我正在尝试使用svcutil生成WCF代理类来访问此服务。
我在svcutil中发现了明显的代码生成错误。这似乎是因为有两个单独的SOAP操作共享一个公共输入消息（使用不同的SOAP操作）并输出两个不同的数组类型。当svcutil生成代码时，两个操作都使用相同的请求类和不同的响应类生成，而OperationContractAttribute用于设置操作的Action。不幸的是，在请求类上设置了MessageContractAttribute，它似乎重写了这一点，导致两个服务调用都包含相同的SOAP操作。
我能够通过手动修改生成的代码来修正此问题，以便使用不同的MessageContractAttribute为第二个操作创建单独的类，并更新所有其他引用以使用此类。但我真的不满意这个解决方案，我正在寻找一种方法来调整WSDL，以便svcutil可以更好地解释它，或者将命令行参数更改为svcutil，以便它可以生成正确的代码。
另外注意，DataContractSerializer无法导入此WSDL，它必须使用XmlSerializer。因此，如果有人可以建议修改WSDL以便DataContractSerializer可以运行的方法，我会很乐意尝试 - 我可以完全控制WSDL。
我能够创建一个非常简单的WSDL来说明这一点：

这是传递给svcutil的命令：
svcutil /noconfig /o:arrayTest.cs ArrayTest.wsdl

答案 0 :(得分：0)
到目前为止，我提出的唯一答案是创建一个具有相同部分的附加消息类型，即：
<wsdl:message name="Array2OperationRequest">
<wsdl:part name="NewOperationRequest" type="xsd:string"/>
</wsdl:message>
我真的不喜欢这个解决方案，因为我创建了一个具有完全相同结构的冗余消息。似乎svcutil 应该能够为相同的消息类型生成不同的SOAP动作。而且，实际上，如果响应不是一个数组，它就可以做到这一点（我已经测试了返回的事件，比如一个bool，他们可以共享相同的请求消息并且代码生成正确）。
