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
