如何识别设置了过滤器的单元格/列？

Question

I am using Microsoft Interop to read the data.

In excel-sheet, multiple random columns have "filters" set. How do I find out which cells /columns have filters set? I would like lo load only the columns that have filters set.

here is how the sheet looks like

row 1-5, col 1-10 [long text describes the data in the sheet, i do not want to load ]

row 1-10, col 1 [some data, not filtered, i do not want to load]

row 1-10, col 2-15 [filter set for some columns only, i would like to detect the filters and load the entire column data ]

Answer 1

• The Worksheet interface has an AutoFilter property that returns an AutoFilter interface.
• The AutoFilter interface has a Filters property that returns a Filters interface.
• The AutoFilter interface has a Range property that returns the range being filtered.
• The Filters interface is a collection of Filter s; these are in the same order as the columns in AutoFilter.Range
• The Filter interface has an On property that indicates whether the column is being filtered.
