Deserialize response in object C#

Question

I have a problem with deserialize xml response

string soapResult; 
using (WebResponse webResponse = webRequest.EndGetResponse(asyncResult)) 
{
   using (StreamReader rd = new StreamReader(webResponse.GetResponseStream())) 
   { 
       soapResult = rd.ReadToEnd(); 
   } 
   return soapResult; 
} 
var dd=CallWebService("cmfs:9115/CMBSpecificWebService/services/‌​…"); 
var doc = XDocument.Parse(dd); 
XmlSerializer s = new XmlSerializer(typeof(RunQueryReply));
var response = doc.Descendants().Where(x => x.Name.LocalName == typeof(RunQueryReply).Name).FirstOrDefault();
       (RunQueryReply)s.Deserialize(response.CreateReader());

An unhandled exception of type 'System.InvalidOperationException' occurred in System.Xml.dll Additional information: There is an error in XML document (0, 0).

Answer 1

It looks like you haven't loaded the document into doc.

var doc = ?????
doc.Load(???xmlfile???);

var response = doc.Descendants().Where(x => x.Name.LocalName == typeof(RunQueryReply).Name).FirstOrDefault();
   (RunQueryReply)s.Deserialize(response.CreateReader());

Answer 2

You are not telling the serialiser what the default namespace is.

Try this:

var stream = new StringReader(dd);
XmlSerializer s = new XmlSerializer(typeof(RunQueryReply), "http://www.ibm.com/xmlns/db2/cm/beans/1.0/schema");
var a = (RunQueryReply) s.Deserialize(stream);
