Question

通过visual studio 11的“服务参考”，在c＃中使用Web服务时，我遇到了一个非常烦人的问题。

我能够通过Web服务（在另一个域上）进行调用并获得响应，但在处理响应时会出现错误：

无法将类型为“System.Xml.XmlNode []”的对象强制转换为类型 ComplexType_Client_InformationResponse

这是wsdl：

......和回复：

<?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" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" 
    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，并在替换时成功地使其工作

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

通过

<return>

通过VS 11中的服务引用在c＃中使用Web服务
