I am a little bit confused on the concept of using a List Class. Here is what
I want to be able to do:

1) I create an object called "NotePage"
2) I want to add several "NotePage" objects to a "NoteBook" List
3) I then want to be able to pass a List Class as a parameter to a method call

Can anyone give me some examples on how to do this or at least point me in
the right direction? I am about to go nuts here.

Thanks.

Noble,

It's pretty simple. You can do this:

// In your code:
List<NotePage> notebook = new List<NotePage>();

// Add your items.
notebook.Add(new NotePage());

And then pass notebook to your methods.

void SomeMethod(List<NotePage> pages)
{
// ...
}

void SomeOtherMethod()
{
List<NotePage> NoteBook = new List<NotePage>();
NotePage page = new NotePage();

NoteBook.Add(page);

SomeMethod(NoteBook);
}

You can also do this:

public class Employee
{}

public class EmployeeCollection : List <Employee>
{

}

This will give you instant strong typed collections.....a vast improvement
over 1.1 CollectionBase stuff.

You don't have to do this, you just ~can do this.

List <Employee> allEmployees = new List <Employee>();

works as well.
