在VBA For循环中使用两个以上范围

Question

因此，我尝试使用For循环在Excel中的三个单独列中进行操作。

Sub dostuff()
  Dim lRw As Long, C As Range

  ' Get number of active rows by finding last row index.
  lRw = Range("A" & Rows.Count).End(xlUp).Row

  For Each C In Range("B1:B" & lRw, "H1:H" & lRw)
  ' stuff happens
  Next
End Sub

当我仅如上所述指定一个或两个列范围时，这很好用，但是当我尝试添加第三个列范围时，它失败了：

For Each C In Range("B1:B" & lRw, "H1:H" & lRw, "M1:M" & lRw)

有没有办法遍历三列（或更多列）而不是两列？

Answer 1

在循环之前，只需做一个联合以合并您的范围

Dim loopRange as Range
Set loopRange = Union(Range("B1:B" & lRw),Range("H1:H" & lRw),Range("M1:M" & lRw))
For Each C In loopRange
    'stuff
Next C

Answer 2

Sub Tester()
Dim c As Range, lRw As Long

    lRw = 5
    For Each c In Range("B1:B" & lRw & ",H1:H" & lRw & ",M1:M" & lRw).Cells
        Debug.Print c.Address(False, False)
    Next c

End Sub
