OpenXml 2.0 读取Excel

Excel 单元格中的数据类型包括7种：

Boolean、Date、Error、InlineString、Number、SharedString、String

读取源代码：

 List<string> returnList = new List<string>();
             using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Open(filename, false))
             {
                 foreach (Sheet sheet in spreadsheetDocument.WorkbookPart.Workbook.Descendants<Sheet>())
                 {
                     returnList.Add(sheet.Name);
                 }

                 foreach (Sheet sheet in spreadsheetDocument.WorkbookPart.Workbook.Descendants<Sheet>())
                 {
                     IEnumerable<Sheet> IEnumerableSheet = spreadsheetDocument.WorkbookPart.Workbook.Descendants<Sheet>().Where(s => s.Name == sheet.Name);
                     WorksheetPart worksheetPart = (WorksheetPart)spreadsheetDocument.WorkbookPart.GetPartById(IEnumerableSheet.First().Id);
                     IEnumerable<Row> rows  = worksheetPart.Worksheet.Descendants<Row>();
                     SharedStringTable sharedStringTable = spreadsheetDocument.WorkbookPart.SharedStringTablePart.SharedStringTable;
                     foreach (Row row in rows)
                     {
                         foreach (Cell cell in row.Descendants<Cell>())
                         {
                             if (cell.ChildElements.Count == )
                             {

                             }
                             else
                             {
                                 if (cell.DataType != null)
                                 {
                                      //获取其中共享数据类型
                                     if (cell.DataType.Value == CellValues.SharedString)
                                     {
                                        string cellValue = sharedStringTable.ChildElements[int.Parse(cell.CellValue.InnerText)].InnerText;
                                        returnList.Add(cellValue);
                                     }
                                 }
                             }

                         }
                     }
                 }
                 return returnList;
             }

其中Bool类型数据0会处理为False 1处理成True；

其中最不好处理的数据就是时间Date；

因为工作需要，目前只处理共享数据
