WCF客户端ASP.NET Core3.1中的XML响应解析异常

如何解决WCF客户端ASP.NET Core3.1中的XML响应解析异常

我使用Connected Service功能将soap wcf Web服务连接到我的asp.net core 3.1并生成了Reference.cs文件，但是每当我尝试调用其中一种wcf Web服务方法时，我都会得到xml解析错误。我无法控制wcf网络服务，因此无法更改响应xml。

这是完整的堆栈跟踪：

  System.ServiceModel.CommunicationException: Error in deserializing body of reply message for operation 'getSubjectFieldsByName'.
 ---> System.InvalidOperationException: There is an error in XML document (1,254).
 ---> System.Xml.XmlException: End element 'item' from namespace '' expected. Found element 'subjectDnField' from namespace ''. Line 1,position 254.

我记录了xml请求，并从wcf响应，并且提示正确。
响应xml是：

<?xml version="1.0" encoding="utf-16"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
  <env:Header />
  <env:Body>
    <ns1:getSubjectFieldsByNameResponse xmlns:ns1="https://localhost:8443/ira/ws">
      <return xmlns:ns2="https://localhost:8443/ira/ws">
        <item>
          <subjectDnField>DN_PKIX_COMMONNAME</subjectDnField>
          <defaultValue></defaultValue>
          <isRequired>true</isRequired>
          <isModifiable>true</isModifiable>
        </item>
        <item>
          <subjectDnField>DN_PKIX_SERIALNUMBER</subjectDnField>
          <defaultValue></defaultValue>
          <isRequired>true</isRequired>
          <isModifiable>true</isModifiable>
        </item>
      </return>
    </ns1:getSubjectFieldsByNameResponse>
  </env:Body>
</env:Envelope>  

在Reference.cs中为此函数生成的类和方法如下：

[OperationContractAttribute(Action="",ReplyAction="*")]
[FaultContractAttribute(typeof(CA2ServiceReference.InvalidEndEntityProfileNameException),Action="",Name="InvalidEndEntityProfileNameException")]
[FaultContractAttribute(typeof(CA2ServiceReference.RaServiceException),Name="RaServiceException")]
[XmlSerializerFormatAttribute(SupportFaults=true)]
Task<getSubjectFieldsByNameResponse> getSubjectFieldsByNameAsync(getSubjectFieldsByNameRequest request);  

[EditorBrowsableAttribute(EditorBrowsableState.Advanced)]
System.Task<getSubjectFieldsByNameResponse> RaService.getSubjectFieldsByNameAsync(getSubjectFieldsByNameRequest request)
{
    return base.Channel.getSubjectFieldsByNameAsync(request);
}
    
public Task<getSubjectFieldsByNameResponse> getSubjectFieldsByNameAsync(string profileName)
{
    getSubjectFieldsByNameRequest inValue = new getSubjectFieldsByNameRequest();
    inValue.profileName = profileName;
    return ((RaService)(this)).getSubjectFieldsByNameAsync(inValue);
}

我不确定问题出在哪里，所以我尝试包括我认为与该问题有关的大部分内容
我试图更改几个属性和参数，但是得到的最好结果是一个空的输出对象。这是关于生成错误的类和xml属性的错误吗？如何解决解析过程？
