Decorator pattern

Hi,

I have a class like this,

public class OrgChartBasicInfo
    {
        public int UserId { get; set; }
        public int ManagerUserId { get; set; }
        public string FullName { get; set; }
        public string CompanyName { get; set; }
        public string CurrentPosition { get; set; }

    }

Am adding these values to a collection like this

private static List GetEmployees()
        {
            List Employees = new List();
            OrgChartBasicInfo ChildInfo = new OrgChartBasicInfo();
            ChildInfo.UserId = 1;
            ChildInfo.ManagerUserId = 0;
            ChildInfo.FullName = "Employee1";
            ChildInfo.CompanyName = "Abc Company";
            ChildInfo.CurrentPosition = "Reg. Director of Sales ";
            Employees.Add(ChildInfo);
            return Employees;
             }

I want to add one more property to my collection without modifying my class.

I want to add

Collapsed = 1;

in to my collection without editing my class OrgChartBasicInfo.

How can i do this?
Any help?

Thanks,
Priya

You could create a class which inherits from OrgChartBasicInfo

public class OrgChartBasicInfoEx : OrgChartBasicInfo
{
public int Collapsed {ger;set;}
}

You can then add either type of object to your List:

private static List GetEmployees()
{
List Employees = new List();
OrgChartBasicInfoEx ChildInfo = new OrgChartBasicInfoEx();
ChildInfo.UserId = 1;
ChildInfo.ManagerUserId = 0;
ChildInfo.FullName = "Employee1";
ChildInfo.CompanyName = "Abc Company";
ChildInfo.CurrentPosition = "Reg. Director of Sales ";
ChildInfo.Collapsed = 1;
Employees.Add(ChildInfo);
return Employees;
}
