如何在Excel中应用高级过滤器后获取可见行的范围（VBA）

Question

以下代码使用 Sheet2 上的值范围（条件范围）对 Sheet1 工作表（列表范围）上的 A 列应用高级筛选器：

Range("A1:A100").AdvancedFilter Action:=xlFilterInPlace, CriteriaRange:= _
        Sheets("Sheet2").Range("A1:A10"), Unique:=False

运行此代码后，我需要对屏幕上当前可见的行执行一些操作。

目前我使用这样的代码：

For i = 1 to maxRow
   If Not ActiveSheet.Row(i).Hidden then
     ...do something that I need to do with that rows
   EndIf
Next

是否有任何简单的属性可以在应用高级过滤器后为我提供一系列可见的行？

Answer 1

ActiveSheet.Range("A1:A100").Rows.SpecialCells(xlCellTypeVisible)

这会产生一个

Range

对象。

Answer 2

Lance 的解决方案适用于大多数情况。

但是，如果您处理大型/复杂的电子表格，您可能会遇到“SpecialCells Problem”。简而言之，如果创建的范围导致超过 8192 个非连续区域（并且“可能”发生），那么当您尝试访问 SpecialCells 时，Excel 将抛出错误，并且您的代码将无法运行。如果您的工作表足够复杂，您预计会遇到此问题，那么建议您坚持使用循环方法。 值得注意的是，这个问题不在于 SpecialCells 属性本身，而在于 Range 对象。这意味着，每当您尝试获取可能非常复杂的范围对象时，您都应该使用错误处理程序，或者按照您已经完成的操作进行操作，这将使您的程序处理该范围的每个元素（将范围向上）。

另一种可能的方法是返回 Range 对象数组，然后循环访问该数组。我已经发布了一些示例代码来使用。但应该注意的是，只有当您希望描述问题或者您只是想确保您的代码是健壮的时，您才应该关心这个问题。否则这只是不必要的复杂性。

Answer 3

AutoFilter.Range

：

ActiveSheet.AutoFilter.Range.SpecialCells(xlCellTypeVisible)

Answer 4

Excel.Range visibleRange = Excel.Application.ActiveWindow.VisibleRange

希望这有帮助。
