问题：我的代码总是返回一行而不是 13。

代码：

Excel.Application xlApp = null;
Excel.Workbook xlWorkBook = null;
Excel.Worksheet xlWorkSheet = null;
Excel.Range xlrange = null;

string sCurrentDir = Directory.GetCurrentDirectory();

xlApp = new Excel.Application();

xlWorkBook = xlApp.Workbooks.Open(sCurrentDir + @"\Res\res.xlsx", 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, 0, true, 1, 0);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

xlrange = xlWorkSheet.UsedRange;       
xlrange.AutoFilter(5, "4", Excel.XlAutoFilterOperator.xlFilterValues, Type.Missing, true);

Excel.Range filteredRange = xlrange.SpecialCells(Excel.XlCellType.xlCellTypeVisible,    Excel.XlSpecialCellsValue.xlTextValues);

MessageBox.Show(filteredRange.Rows.Count.ToString());

如您所见，我想用值“4”过滤第 5 列。它应该返回 13 行，但它总是返回 1 行。

任何帮助将不胜感激
