以下代码使用Sheet2 (条件范围)上的值范围对Sheet1工作表(列表范围)上的列A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。
目前我使用的代码如下:
For i = 1 to maxRow
If Not ActiveSheet.Row(i).Hidden then
...do something that I need to do with that rows
EndIf
Next有没有什么简单的属性可以让我在应用高级过滤器后看到一系列的行?

ActiveSheet.Range("A1:A100").Rows.SpecialCells(xlCellTypeVisible)这将生成一个Range对象。

兰斯的解决方案在大多数情况下都有效。
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(这是可能发生的),那么当您尝试访问SpecialCells时,Excel将抛出一个错误,并且您的代码将无法运行。如果您的工作表足够复杂,您可能会遇到这个问题,那么建议您坚持使用循环方法。
值得注意的是,这个问题不是SpecialCells属性本身的问题,而是Range对象的问题。这意味着,当您试图获取一个非常复杂的range对象时,您应该雇佣一个错误处理程序,或者像您已经做过的那样,这将导致您的程序在range的每个元素上工作(拆分range )。
另一种可能的方法是返回一个Range对象数组,然后遍历该数组。我已经发布了一些示例代码以供参考。然而,应该注意的是,只有当您希望描述问题,或者只是希望确保代码健壮时,才应该为此而烦恼。否则,这只是不必要的复杂性。

您可以使用以下代码来获取单元格的可见范围:
Excel.Range visibleRange = Excel.Application.ActiveWindow.VisibleRange希望这能有所帮助。
