i attempting deserialize class object failing every time.

this code far:

using system; 

using system.collections.generic; using system.text; using system.io; using system.xml.serialization;

namespace deserializexml { public class program {

    // class deserialized.     [serializable()]     public class tradefill     {         [xmlelement("broker")]         public string broker;          [xmlelement("qwfilltransid")]         public string qwfilltransid;          [xmlelement("qwprevtransid")]         public string qwprevtransid;          [xmlelement("qwgrouptransid")]         public string qwgrouptransid;          [xmlelement("grouptransid")]         public string grouptransid;          [xmlelement("transid")]         public string transid;          [xmlelement("service")]         public string service;          [xmlelement("exchange")]         public string exchange;          [xmlelement("instclass")]         public string instclass;          [xmlelement("instsubclass")]         public string instsubclass;          [xmlelement("contractsymbol")]         public string consymbol;          [xmlelement("expirationdate")]         public datetime expdate;          [xmlelement("month")]         public int month;          [xmlelement("year")]         public int year;          [xmlelement("strike")]         public double strike;          [xmlelement("tradepcu")]         public string tradepcu;          [xmlelement("buy")]         public int buy;          [xmlelement("quantity")]         public int quantity;          [xmlelement("price")]         public double price;          [xmlelement("filltime")]         public datetime filltime;          [xmlelement("posupdated")]         public string posupdated;      }       [xmlrootattribute("tradefills")]     public class sigtrades     {         [xmlelement("tradefills")]         public tradefill[] tradefills{ get; set; }     }       [serializable()]     public class test     {          public static void main()         {             test t = new test();           // read purchase order.             t.deserializeobject("c:\\test.xml");         }          private void deserializeobject(string filename)         {                console.writeline("reading stream");             // create instance of xmlserializer.             xmlserializer serializer =             new xmlserializer(typeof(tradefill));             // reading xml document requires filestream.             stream reader= new filestream(filename,filemode.open);              // declare object variable of type deserialized.             tradefill i;              // call deserialize method restore object's state.             = (tradefill)serializer.deserialize(reader);              // write out properties of object.             console.write(i.qwfilltransid);         }     }   } 

}

when execute it, see "reading stream" on console, , nothing else.

edit

i realized 'reading stream" because still reading. after 5 seconds, got:

edit

after making program class public, error:

edit

made bunch of changes code (as reflected above). had items listed twice, double checked case etc. error:

unhandled exception: system.invalidoperationexception: there error in xml document (2, 2). ---> system.invalidoperationexception: <tradefills xmlns=''> wa s not expected.    @ microsoft.xml.serialization.generatedassembly.xmlserializationreadertradef ill.read3_tradefill()    --- end of inner exception stack trace --- 

1. element qwgrouptransid mentioned twice. have in own element , name on grouptransid, deserializer doesn't know put values it.
2. your value filltime invalid.
3. you're trying deserialize tradefill, actual xml carcollection.
