excelApp = new Microsoft.Office.Interop.Excel.Application();
               excelWBs = excelApp.Workbooks;
               excelWB = excelWBs.Add(Type.Missing);
excelWB = excelApp.Workbooks.Open(filePath, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
                                  Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
                   excelSheets = excelWB.Sheets;
                   excelWSheet = excelSheets.get_Item(1) as Excel._Worksheet;
                   excelWSheet.Activate();
                   range = excelWSheet.UsedRange;
               int intRowCount = range.Rows.Count;为什么明明我的Excel文件里面只用了5行,但是intRowCount返回的却是15行,哪位高手能帮忙看看到底哪里出了问题?有什么方法可以解决吗?
