How to clear the entire array?

Question

I have an array like this:

Dim aFirstArray() As Variant

How do I clear the entire array? What about a collection?

Answer 1

Find a better use for myself: I usually test if a variant is empty, and all of the above methods fail with the test. I found that you can actually set a variant to empty:

Dim aTable As Variant
If IsEmpty(aTable) Then
    'This is true
End If
ReDim aTable(2)
If IsEmpty(aTable) Then
    'This is False
End If
ReDim aTable(2)
aTable = Empty
If IsEmpty(aTable) Then
    'This is true
End If
ReDim aTable(2)
Erase aTable
If IsEmpty(aTable) Then
    'This is False
End If

this way i get the behaviour i want
