我在我的 WCF 服务中使用以下数据协定，当我的客户端是 C# 控制台应用程序时它可以工作

[DataContract]
public class PersonField
{
    private string _fieldName;
    private object _fieldValue;

    public PersonField()
    {
    }

    public PersonField(string FieldName, object FieldValue)
    {
        _fieldName = FieldName;
        _fieldValue = FieldValue;
    }
    [DataMember]
    public string FieldName
    {
        get { return _fieldName; }
        set { _fieldName = value; }
    }
    [DataMember]
    public object FieldValue
    {
        get { return _fieldValue; }
        set { _fieldValue = value; }
    }
}

但

当我从 SOAP UI(http://www.soapui.org/) 尝试它时，我得到以下响应

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
   <s:Body>
      <s:Fault>
         <faultcode xmlns:a="http://schemas.microsoft.com/net/2005/12/windowscommunicationfoundation/dispatcher">a:DeserializationFailed</faultcode>
         <faultstring xml:lang="en-US">The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter entities. The InnerException message was 'Element FieldValue from namespace http://schemas.datacontract.org/2004/07/Entities.Person cannot have child contents to be deserialized as an object.

      </s:Fault>
   </s:Body>
</s:Envelope>

我不能在 WCF 中使用类型对象吗？

For SoapUI it does not know what types could be in object. You have to define the known types so that the schema (WSDL) exposes them to SoapUI. Have a look at this MSDN article

You should have something like

[DataContract]
[KnownType(typeof(Type1))]
[KnownType(typeof(Type2))]
public class PersonField { ... }

我没有尝试过，但我认为你不能。如果实体是对象类型，则无法明确指定合同，因为您无法提前知道类型，正如预期的那样。
