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：

 1 List<string> returnList = new List<string>();

 2             using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Open(filename, false))

 3             {

 4                 foreach (Sheet sheet in spreadsheetDocument.WorkbookPart.Workbook.Descendants<Sheet>())

 5                 {

 6                     returnList.Add(sheet.Name);

 7                 }

 8 

 9                 foreach (Sheet sheet in spreadsheetDocument.WorkbookPart.Workbook.Descendants<Sheet>())

10                 {

11                     IEnumerable<Sheet> IEnumerableSheet = spreadsheetDocument.WorkbookPart.Workbook.Descendants<Sheet>().Where(s => s.Name == sheet.Name);

12                     WorksheetPart worksheetPart = (WorksheetPart)spreadsheetDocument.WorkbookPart.GetPartById(IEnumerableSheet.First().Id);

13                     IEnumerable<Row> rows  = worksheetPart.Worksheet.Descendants<Row>();

14                     SharedStringTable sharedStringTable = spreadsheetDocument.WorkbookPart.SharedStringTablePart.SharedStringTable;

15                     foreach (Row row in rows)

16                     {

17                         foreach (Cell cell in row.Descendants<Cell>())

18                         {

19                             if (cell.ChildElements.Count == 0)

20                             {

21 

22                             }

23                             else

24                             {

25                                 if (cell.DataType != null)

26                                 {

27                                      //获取其中共享数据类型

28                                     if (cell.DataType.Value == CellValues.SharedString)  

29                                     {

30                                        string cellValue = sharedStringTable.ChildElements[int.Parse(cell.CellValue.InnerText)].InnerText;

31                                        returnList.Add(cellValue);

32                                     }

33                                 }

34                             }

35 

36                         }

37                     }

38                 }

39                 return returnList;

40             }

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
