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 == 0)
                            {

                            }
                            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
