for the xml object i get the below string

"      <bookshare>\n  <version>4.1.2</version>\n  <messages>\n    <string>Invalid/Incorrect ISBN number</string>\n  </messages>\n  <status-code>85</status-code>\n</bookshare>\n\n    \n"

and in a bookshare class i have the below code

public class bookshare

    public string version { set; get; }
    public string messages { set; get; }
    public string statusCode { set; get; }
        Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
    public book[] b;

    public bookshare()


i am able to retrieve the data for version and message, but when i try to retrieve the data for statu-code it give me a nullreference exception
i retrieve the data as

var reader = new StringReader(res);
        var serializer = new XmlSerializer(typeof(bookshare));
        var instance = (bookshare)serializer.Deserialize(reader);

        string version = instance.version.ToString();
        string message = instance.messages.ToString();
        string eCode = instance.statusCode.ToString();

what is the problem to get null? the varaible has a value
thanks appreciate a reply



the xml string

<bookshare>\n  <version>4.1.2</version>\n  <messages>\n    <string>Invalid/Incorrect ISBN number</string>\n  </messages>\n  <status-code>85</status-code>\n</bookshare>\n\n    \n"

i am trying to get the status-code but it is returning no value

why is returning a null value ? can't figure it out?
