Use VBA to get Unique values for use within VBA?

问题:

I currently would use something like this either with Range, Cells or the like many different ways same basic principle.

Range("A1", Range("A1").End(xlDown)).AdvancedFilter Action:=xlFilterCopy, _
    CopyToRange:=Range("IV1"), Unique:=True

Dim myArr as Variant 
myArr = Range("IV1", Range("IV1").End(xlDown))
Columns("IV").Delete

Is there a way to directly load those unique values into any type of object in VBA without the need to copy to another location?

回答1:

You can use a Collection Object to create unique entries. For example

Sub Sample()
    Dim Col As New Collection
    Dim itm
    Dim i As Long
    Dim CellVal As Variant

    '~~> Lets say looping through Row 1 to 22 For 
    '~~> Range("A1:A22") as mentioned in your recent comment
    For i = 1 To 22
        CellVal = Sheets("Sheet1").Range("A" & i).Value
        On Error Resume Next
        Col.Add CellVal, Chr(34) & CellVal & Chr(34)
        On Error GoTo 0
    Next i

    For Each itm In Col
        Debug.Print itm
    Next
End Sub
