| ArrayList: AddRange |
Adds the items from a collection to the list.
Public Sub AddRange( ByRef c As Variant )
The elements in the collection added by using For..Each to iterate each element. The elements are added to the end of the list in the same order as the For..Each loop produces them.
If the number of elements to be added is more than the available capacity in the ArrayList, then the capacity is increased to accommodate the collection of elements.
| Exception Type | Condition |
|---|---|
| ArgumentNullException | c is an uninitialized array. - or - c is Nothing. |
| NotSupportedException | The ArrayList is Read-Only - or - The ArrayList is Fixed-Size. |
| InvalidCastException | c is not a VBA.Collection, ICollection object, or an Array. |
An ArrayList is created and filled with an initial set of elements, then a Queue is filled with additional elements that will be added to the ArrayList using AddRange.
Private Sub Main()
Dim list As New ArrayList
' add several elements to the ArrayList
list.Add "Humpty"
list.Add "Dumpty"
list.Add "sat"
list.Add "on"
list.Add "a"
list.Add "wall."
' Display the contents of the ArrayList
Console.WriteLine "The ArrayList initially contains:"
PrintValues list
Dim que As New Queue
que.Enqueue "Humpty"

que.Enqueue "had"
que.Enqueue "a"
que.Enqueue "great"
que.Enqueue "fall."
' Display the contents of the Queue
Console.WriteLine "The Queue initially contains:"
PrintValues que
' Add the elements in the Queue to the ArrayList
list.AddRange que
' Display the new contents of the ArrayList
Console.WriteLine "The ArrayList with the elements from the Queue:"

' Wait for user to press return key
Console.ReadLine

' This code produces the following output.
