高级过滤器优于c＃ [英] advanced filter excel with c#

问题描述

我需要在excel表中做一个过滤器，我想知道是否可以做这样的过滤器

I need to do a filter in a excel sheet, I would like to know if is possible do a filter like this

 List<string> listFilter = new List<string>();
            listFilter.Add("3");
            listFilter.Add("4");

            object _missing = System.Reflection.Missing.Value;
            Microsoft.Office.Interop.Excel.Range oRng1 = xlWorkSheet.Range["A1", "A1048576"];
            oRng1.AutoFilter(1, listFilter, Microsoft.Office.Interop.Excel.XlAutoFilterOperator.xlAnd, _missing, true);
            oRng1.Borders.LineStyle = Microsoft.Office.Interop.Excel.XlLineStyle.xlContinuous;

我知道这段代码不起作用，但我想在筛选器中做一个dinamic列表参数。
有人可以告诉我我该怎么做？

I know that this code doesn't work but I would like to do a dinamic list in the filter parameter. Could someone tell me how can I do this?

推荐答案

我不知道传递列表，但你可以传递数组：

I'm not sure about passing lists, but you can definitely pass arrays:

string[] listfilter = new string[] { "2", "3", "4" };
xlWorksheet.get_Range("A1", "B50").AutoFilter(1, listfilter, Excel.XlAutoFilterOperator.xlFilterValues,
    Missing.Value, true);

您可以找到 XlAutoFilterOperator的不同成员 此处。

尝试找到工作表中最后使用的行，而不是为整个列设置过滤器，这可能会减慢一些问题：

It might also be an idea to try to find the last-used row in the sheet rather than setting the filter for the entire column as that might slow things down a little:

int lastRow = xlWorksheet.Range["A:A"].Find("*", Missing.Value, Missing.Value, Missing.Value,
    Excel.XlSearchOrder.xlByRows, Excel.XlSearchDirection.xlPrevious, false, Missing.Value,
    Missing.Value).Row;
