Need Help in Arrays

[Islam Elkhayat]

here is my class
public class AppointmentRowCollection : Appointment
{
public Appointment[] GetRowsCollection(out int rows)
{
int i = 0;
dataset= new AppointmentDS();
dataset= SelectAppointment();
DataRowCollection drcollection = dataset.Appointments.Rows;
rows = drcollection.Count;
foreach (DataRow row in drcollection)
{
AppointmentID = int.Parse(row["AppointmentID"].ToString());
AppointmentDate= Convert.ToDateTime(row["AppointmentDate"]);
TimeFrom= row["TimeFrom"].ToString();
TimeTo= row["TimeTo"].ToString();
return new Appointment();
}
return null;
}
}

AppointmentID,AppAppointmentDate....... is a public property From
Appointment Class
How ca i return Appointment[] array form my foreach loop??

I am not going to go into this - but why do you have a collection inheriting
from the object it is a collection of? This is a poor design. Rather, it
should inherit from CollectionBase (if .NET <= v1.1) or (use generics .NET

= 2.0).
Secondly, I would do the following -

Create an ArrayList and for each Appointment, just go ArrayList.add(new
Appointment() );

Then, return the ArrayList.ToArray() result.

Let me know if this works.

Take care.
