asp.net - How to create multiple classes in single DTO class? -

i used making separate business object , list<> classes db tables. have basic task in hand displaying list of year search box or having values in drop down.

right ending lot of separate classes , list classes<> these basic operations.

how can make single class basic tasks these using generics? want have single class methods current year, employee names, department name/code, title etc. please give me example. using .net 2.0.

edit after searching, found can achieve similar tasks creating dto namespace.

what don't right how create multiple classes inside dto class. 1 class returning 'year', 1 'employee name/code' , on inside single dto class.

you can map classes db table manually or can use nhibernate advanced orm works quiet .net 2.0.

basically can map plain c# classes db table using simple xml mapping file.

example class called product can

public class product     {         public guid id { get; set; }         public string name { get; set; }         public string category { get; set; }         public bool discontinued { get; set; }     } 

can mapped db table using following mapping file.

<?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"                     assembly="firstsolution"                     namespace="firstsolution.domain">    <class name="product">     <id name="id">       <generator class="guid" />     </id>     <property name="name" />     <property name="category" />     <property name="discontinued" />   </class>  </hibernate-mapping> 

this has support .net collections. there sure learning curve productivity benefit worth.
