响应属性包含NULL值-WCF

问题描述

我在尝试解决问题时遇到了麻烦，也许你可以帮我

我正在使用具有以下绑定配置的WCF调用WebService

   private static System.ServiceModel.Channels.Binding CreateBinding() 
    {
        var securityElement = SecurityBindingElement.CreateUserNameOverTransportBindingElement();
        securityElement.IncludeTimestamp = false;

        var encodingElement = new TextMessageEncodingBindingElement(MessageVersion.Soap11,Encoding.UTF8);
        var transportElement = new HttpsTransportBindingElement();
        System.ServiceModel.Channels.CustomBinding custom = new System.ServiceModel.Channels.CustomBinding(securityElement,encodingElement,transportElement);
        return custom;
    }

致电服务部门

var client = new ServiceReference1.QueryPortTypeClient(CreateBinding(),"https://...");
ClientResponse response = client.query(request);

服务响应没有问题，但是ClientResponse对象的声明属性为NULL

响应消息的结构

[System.ServiceModel.MessageContractAttribute(WrapperName = "QueryRCEResponse",WrapperNamespace = "urn:wco:datamodel:PE:Declaration:1")]
public class ClientResponse
{
    [System.ServiceModel.MessageBodyMemberAttribute(Namespace = "urn:wco:datamodel:PE:Declaration:1",Order = 0)]
    public Declaration Declaration;

    public ClientResponse()
    {
    }

    public ClientResponse(Declaration Declaration)
    {
        this.Declaration = Declaration;
    }
}

[System.Xml.Serialization.XmlTypeAttribute(Namespace = "urn:wco:datamodel:PE:Declaration:1")]

public class Declaration 
{

    private string functionCodeField;

    [System.Xml.Serialization.XmlElementAttribute(Order = 0)]
    public string FunctionCode
    {
        get
        {
            return this.functionCodeField;
        }
        set
        {
            this.functionCodeField = value;
        }
    }
}

响应消息XML SOAP

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" />
  <soapenv:Body>
    <NS1:QueryRCEResponse xmlns:NS1="urn:wco:datamodel:PE:Declaration:1">
      <Declaration>
        <FunctionCode>2020-840485</FunctionCode>
       </Declaration> 
    </NS1:QueryRCEResponse>
  </soapenv:Body>
</soapenv:Envelope>
