Question

我正在使用WCF .Net 4.0来调用用Java编写的Web服务。 WSDL的一部分引用了SPML 2.0，我附上了一些代码来描述发生了什么。

WSDL引用了一些XSD，我正在使用的部分是

<?xml version="1.0" encoding="utf-8"?>
<xsd:schema xmlns:spml="urn:oasis:names:tc:SPML:2:0" xmlns:sec="urn:corp:iam:spml2:security" xmlns="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" targetNamespace="urn:corp:iam:spml2:security" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:import schemaLocation="../oasis-spml-xsds/pstc_spmlv2_core.xsd" namespace="urn:oasis:names:tc:SPML:2:0" />
  <xsd:complexType name="SuggestUserIDResponseType">
    <xsd:complexContent mixed="false">
      <xsd:extension base="spml:ResponseType">
        <xsd:sequence>
          <xsd:element minOccurs="1" maxOccurs="5" name="uid" type="xsd:string" />
        </xsd:sequence>
      </xsd:extension>
    </xsd:complexContent>
  </xsd:complexType>
</xsd:schema>

和

<?xml version="1.0" encoding="utf-8"?>
<xsd:schema xmlns:spml="urn:oasis:names:tc:SPML:2:0" xmlns="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" targetNamespace="urn:oasis:names:tc:SPML:2:0" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:complexType name="ExtensibleType">
    <xsd:sequence>
      <xsd:any minOccurs="0" maxOccurs="unbounded" namespace="##other" processContents="lax" />
    </xsd:sequence>
    <xsd:anyAttribute namespace="##other" processContents="lax" />
  </xsd:complexType>
  <xsd:complexType name="ResponseType">
    <xsd:complexContent mixed="false">
      <xsd:extension base="spml:ExtensibleType">
        <xsd:sequence>
          <xsd:element minOccurs="0" maxOccurs="unbounded" name="errorMessage" type="xsd:string" />
        </xsd:sequence>
        <xsd:attribute name="status" type="spml:StatusCodeType" use="required" />
        <xsd:attribute name="requestID" type="xsd:ID" use="optional" />
        <xsd:attribute name="error" type="spml:ErrorCode" use="optional" />
      </xsd:extension>
    </xsd:complexContent>
  </xsd:complexType>
</xsd:schema>

因此WCF服务引用生成的代理类是

            this.RaisePropertyChanged("uid");
        }
    }

在其中一个服务调用中，返回的SOAP消息是

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <ns3:suggestUserIDResponse status="success" requestID="MyApp" xmlns="urn:oasis:names:tc:SPML:2:0" xmlns:ns2="urn:oasis:names:tc:SPML:2:0:password" xmlns:ns3="urn:corp:iam:spml2:security" xmlns:ns4="urn:oasis:names:tc:SPML:2:0:suspend" xmlns:ns5="urn:oasis:names:tc:SPML:2:0:search" xmlns:ns6="urn:oasis:names:tc:SPML:2:0:DSML" xmlns:ns7="urn:oasis:names:tc:DSML:2:0:core" xmlns:ns8="urn:oasis:names:tc:SPML:2:0:batch">
         <ns3:uid>text1</ns3:uid>
         <ns3:uid>text2</ns3:uid>
         <ns3:uid>text3</ns3:uid>
      </ns3:suggestUserIDResponse>
   </soap:Body>
</soap:Envelope>

此时，SOAP未正确反序列化为SuggestUserIDResponseType类，SuggestUserIDResponseType.uid始终为空，但重复的uid仅在SuggestUserIDResponseType.Any中显示为XmlElement数据类型。

有什么建议吗？

Answer 1

我刚遇到同样的问题。看起来问题与使用public System.Xml.XmlElement[] Any属性修饰的XmlAnyElementAttribute属性和Order限定符集的组合有关。也可能只有在从具有XmlElement[] Any数组的基类继承时才会发生。

我的解决方案是删除所有继承类中的XmlElementAttribute属性，XmlAnyElementAttribute属性和MessageBodyMemberAttribute属性 中的订单限定符 < /强>

注意：粗体斜体中的那个位很重要，否则您会收到如下错误：

键入成员＆＃34; XYZ＆＃34;声明在＆＃34; ABC_Type＆＃34;缺少必需的订单＆＃39; 属性。如果类层次结构中的一个类使用显式排序功能（Order），然后是它的基类和所有派生的课程必须做同样的事情

我还没有完成这项研究以检查可能出现的副作用 - 有一点很重要，可能是你的属性在你的班级中按照正确的顺序排列，以便序列化以正确的顺序发生。 / p>
希望这有助于某人。
