❔ Excel column filter

Using VSTO/interop I'm trying to filter an excel sheet based on a column containing integer IDs. My plugin collects an array of integers and then tries to filter the column:

            vstoSheet.Range["A1:A10"].AutoFilter(1, new int[]{1,2,3}, Excel.XlAutoFilterOperator.xlFilterValues, System.Type.Missing, true);

            vstoSheet.Range["A1:A10"].AutoFilter(1, new int[]{1,2,3}, Excel.XlAutoFilterOperator.xlFilterValues, System.Type.Missing, true);

I've tried to reason about why it doesn't work but every possible combination of options I could think of just resulted in all elements being filtered. The expected behaviour is to only have the elements in the provided list being displayed.

Holy moly I've solved it. You need to use a string array even if your datatype is an int. -5 hours
