我在WCF服务中使用下面的数据协定,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.

</s:Fault>
</s:Body>
</s:Envelope>
不能在 WCF 中使用类型对象吗?
我没有尝试过,但我认为你不能。如果实体是对象类型,则无法明确指定协定,因为您无法按预期提前知道类型。
对于SoapUI,它不知道object
中可能有哪些类型。您必须定义已知类型,以便模式 (WSDL) 将它们公开给 SoapUI。查看此 MSDN 文章
你应该有类似的东西
[DataContract]
[KnownType(typeof(Type1))]
[KnownType(typeof(Type2))]
public class PersonField { ... }
