How to design this class?

I have a class called CBike

Now I need a class that will act as a collection of bikes..

I want to be able to use for... each and also to access bikes by


mybikecollection.item(3).GetName <-- where getname is a property of CBike

Which framework class should I inherit so that I can do all this? I need one that implements ICollection, and I want it to be pretty fast...

Is it enough to make it like this:

class CVehicleCOllection : inherits Collection

end class


os what enlse is needed?

I need a collection that can store items of a specific type! If I make them an arraylist I need to convert from object to CBike.. I don't want to do that..


kind regards

dim oCBikes as collection

set CBikes as a public property .... and use the .Add .Count etc functions to access your collection

I would do it by inherits CollectionBase.
Something like this:

Code:

---

Public Class CVehicleCOllection
    Inherits CollectionBase
    'The type-safe add method
    Sub Add(ByVal item As CBike)
        Me.List.Add(item)
    End Sub
    'Remove the specified object
    Sub Remove(ByVal item As CBike)
        Me.List.Remove(item)
    End Sub
    'Check that a given element is in the collection
    Function Contains(ByVal item As CBike) As Boolean
        Return Me.List.Contains(item)
    End Function

---

You can also use the InnerList Object which is really usefull:

Code:

---

'Sort the item in the collection
    Sub Sort()
        Me.InnerList.Sort()
    End Sub
    'Return the index of a CBike element
    Function IndexOf(ByVal item As CBike) As Integer
        Return Me.InnerList.IndexOf(item)
    End Function
End Class

---

I hope it help you,

cool ;)

Thanks for the code...

What if I want to remove the entire collection from memory, which is the most efficient way to do it?

mycol.Dispose() ?
