It means that sometimes the order of elements is predictable, sometimes it is
not.
If you enumerate an array or a collection, the order is predictable. Arrays
are enumerated by index, while collections are enumerated by following the
element creation order.
The following code:
Dim aArray As New String[] = [ "blue", "white", "red" ]
Dim aCol As New Collection = [ "a": "blue", "b": "white", "c": "red" ]
Dim sVal As String
For Each sVal in aArray
Print sVal;;
Next
Print
For Each sVal in cCol
Print sVal;;
Next
Print
will print:
blue white red
blue white red
For other enumerable classes, you must suppose that the order of enumeration
is random, unless the contrary is explicitely written in the class
documentation.
