如何使用openxml和c＃在Excel表格中获取范围

我必须读取Excel（.xlsx）文件。 我正在使用OpenXML NuGet pkg。 我想获得范围（ xlRange ），所以我可以从特定的单元格中获取数据。 但没有获得成功。 此代码在控制台环境中创build。

 static void Main(string[] args) { bool flagDataError = false; string sDuplicateRows = string.Empty; string sCreatedRows = string.Empty; string sFileTypeError = string.Empty; string filepath = @"C:\test.xlsx"; var fileName = Path.GetFileName(filepath); var fileExtension = Path.GetExtension(filepath); if ((fileExtension != ".xlsx") && (fileExtension != ".xls")) sFileTypeError = "Invalid file. \n\nPlease browse a correct Excel file to upload."; else { using (SpreadsheetDocument doc = SpreadsheetDocument.Open(filepath, false)) { WorkbookPart workbookPart = doc.WorkbookPart; WorksheetPart worksheetPart = workbookPart.WorksheetParts.First(); SheetData sheetData = worksheetPart.Worksheet.Elements<SheetData>().First(); List<AxisData> data = new List<AxisData>(); for (int i = 5; i <= 16; i++) { for (int j = 2; j <= 13; j++) { AxisData axisDetails = new AxisData(); axisDetails.ProductCode = "AXIS " + xlRange.Cells[i, 1].Value; axisDetails.ContractPeriod = Convert.ToDateTime(xlRange.Cells[4, j].Value); axisDetails.SettlePrice = Convert.ToDecimal(xlRange.Cells[i, j].Value); axisDetails.EffectiveStartDate = efectiveStartDate; } } } } } } }

 IEnumerable<Row> ShRows = sheetData.Elements<Row>(); var _RCount = SHRows.Count();
