what do u actually want??....You cant add a module to a alrady compiled .dll...If you want more functionality from your dll then you have to change the structure and compile the dll again as a new project.

Look, i have modify a created project by chris hambelton,,,theres a DLL file by the name CIF.Business.Northwind contain some Class, like this:

using System;

namespace CIF.Business.Northwind
{
[Serializable]
public class OrdersItem : BusinessItemBase
{
public OrdersItem();

public virtual string CustomerID { get; set; }
public virtual int EmployeeID { get; set; }
public virtual double Freight { get; set; }
--------------------------------------------------------------------------
***Now i want to add a new Parameter to OrdersItem Class in project, Like this:

public virtual string Postalcode { get; set; }

i write these codes:

namespace CIF.Business.Northwind
{
[Serializable]
public class OrdersItem : BusinessItemBase
{
private string _Postalcode;

public OrdersItem() { }

public string Postalcode
{
get { return _Postalcode; }
set { _Postalcode = value; }
}

}

But i Got Errors:

'CIF.Business.Northwind.OrdersItem' does not contain a definition for 'CustomerID'
'CIF.Business.Northwind.OrdersItem' does not contain a definition for 'EmployeeID'

Whats wrong ?!


Really Thanks For Care
