我想按以下代码访问 wcf webservice：
void farmCreate(String userName,
String authToken) {
String resultData = null;
Hashtable<String, String> responseHashTable = new Hashtable<String, String>();
try {
FarmClass farm = new FarmClass();
StringBuilder sb = null;
SoapObject request = new SoapObject(Controller.NAMESPACE, "MethodName");
request.addProperty("aaaa", userName);
request.addProperty("aaaa", authToken);
request.addProperty("aaaa", farm);
request.addProperty("aaaaa", "Add");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
MarshalDate md = new MarshalDate();
md.register(envelope);
MarshalFloat md1 = new MarshalFloat();
md1.register(envelope);
HttpTransportSE androidHttpTransport = new HttpTransportSE(Controller.URL6767);
androidHttpTransport.call(Controller.SOAP_ACTION + "method name", envelope);
//new MarshalBase64().register(envelope);
Object result = (Object) envelope.getResponse();
resultData = result.toString();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
System.out.println("error is occured :-" + e.getMessage());
}
}
但作为回应，产生如下错误：-

所以拜托，任何人都对序列化概念有想法，所以请告诉我。提前致谢。
