Class

Syntax

.CopyTo(array
,index
)
-
array
(required; Array of Objects) Array to which to copy the queue’s objects
-
index
(required; Integer) The index of the first array element to receive an element of the queue
Return Value
None
Description
Copies the queue elements into an array, starting at a specified array index
Rules at a Glance
The array can be of any data type that is compatible with the queue elements. Thus, for instance, we cannot use an Integer array to hold queue elements that are strings (that is, Objects whose subtype is String).
The array must be sized to accommodate the elements of the queue prior to calling the CopyTo method.
Example
' Define a new queue Dim q As New Queue( ) Dim aQueue( ), oItem As Object ' Queue up some items q.Enqueue("Chopin") q.Enqueue("Mozart") q.Enqueue("Beethoven") ' Size the array and copy to it Redim aQueue(q.Count - 1) q.CopyTo(aQueue,0) For Each oItem in aQueue Console.WriteLine(oItem) Next
