通过 Visual Studio 11 中的“服务参考”，我在 C# 中使用 Web 服务时遇到了一个非常烦人的问题。

我可以拨打电话并从 Web 服务（在另一个域上）获得响应，但在处理响应时出现错误：

无法将“System.Xml.XmlNode[]”类型的对象转换为 ComplexType_Client_InformationResponse

这是wsdl：

...和回应：

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope 
    xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
    xmlns:ns1="https://xxx.fr/client"

    SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
  <SOAP-ENV:Body>
    <ns1:informationXResponse>
      <return xsi:type="SOAP-ENC:Struct">
        <ELEMENT1 xsi:type="xsd:int">697438</ELEMENT1>
        <ELEMENT2 xsi:type="xsd:string">DDDD</ELEMENT2>
        <ELEMENT3 xsi:type="xsd:string">CCCC</ELEMENT3>
        <ELEMENT4 xsi:type="xsd:string">VVVVV</ELEMENT4>
        <ELEMENT5 xsi:nil="true"/>
      </return>
    </ns1:informationXResponse>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

使用Fiddler，我开始修改返回的XML，替换时成功让它工作

<return xsi:type="SOAP-ENC:Struct">

经过

<return>
