How to capture array retrieved by the RetrieveMultipleResponse method?

Question

hello everyone!

I have requested a response for my query using the RetrieveMultipleResponse service. How can I extract the array of BusinessEntities from the resultant instance.

 

I have pasted a snippet of my code,

QueryExpression exp = new QueryExpression();
                string[] attributes = new string[] { "fullname" };
                ColumnSet cset = new ColumnSet(attributes);
                exp.ColumnSet = cset;
                exp.EntityName = EntityName.contact.ToString();

                RetrieveMultipleRequest req = new RetrieveMultipleRequest();
                req.Query = exp;


                RetrieveMultipleResponse res = (RetrieveMultipleResponse)service.Execute(req);
                BusinessEntity[] barray = res; *********************PROBLEM IS HERE*********************
               
                foreach (BusinessEntity b in barray)
                    Console.WriteLine((b as contact).fullname);

thanking you in advance,
