RIA returning new objects?

hi,

 i have ria service doing calculations , returning results:

 

public iqueryable getcalculateddata(int mydata1, int mydata2)  {     var returnval = new list();       var mydatacollection = (from x in this.context.mydata x.id = mydata1 select x);     var mydatacollection2 = (from x in this.context.mydata x.id = mydata2 select x);       for(int = 0; < mydatacollection.count(); i++)     {         returnval.add(new mydata         {            value = mydatacollection.tolist().value+mydatacollection2.tolist().value;         });     }     return returnval; //here data correct  }  

 on silverlight app side unexpected results:

private void mydataloaded(loadoperation operation)  {      listbox.itemsource = operation;  }

 in listbox items have same value , first value calculated.

how can return results this?

do need create new domain class can't persisted return these values, or going wrong?

 thanks,

query operations can return entity and ienumerable<t> or  iqueryable<t>, t entity.

if want return array of let's ints can use service operation.
