java客户端调用C#的web service为什么抛出反序列化的异常？

Service service = new Service();
        Call call = null;
        try {
            call = (Call) service.createCall();
            call.setTargetEndpointAddress(new URL(
                    "http://www.webxml.com.cn/WebServices/WeatherWebService.asmx"));
            call.setOperationName(new QName("http://WebXml.com.cn/",
                    "getWeatherbyCityName"));
            call.addParameter(
                    new QName("http://WebXml.com.cn/", "theCityName"),
                    XMLType.SOAP_VECTOR, ParameterMode.IN);
            call.setReturnType(XMLType.SOAP_VECTOR);
            call.setUseSOAPAction(true);
            call.setSOAPActionURI("http://WebXml.com.cn/getWeatherbyCityName");
            System.out.println(call.invoke(new Object[] { "广州" }));
        } catch (Exception e) {
            e.printStackTrace();
        }

代码调用天气的webservice没有问题，当我用客户提供的c#web service的时候，就会出现异常：SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize.大概意思是说什么需要反序列化吧，求大神
