打開XML SDK 2.0使用公式讀取Excel單元格值

Question

我正在使用openXML sdk閱讀excel文件。 一些Excel單元格包含公式，我想讀取單元格的值，但是當我使用下面的代碼時，它將獲取公式。 如何獲得價值。

WorksheetPart wsPart = (WorksheetPart)(wbPart.GetPartById(theSheet.Id));
using(SpreadsheetDocument document = SpreadsheetDocument.Open(fileName, false))
{
  WorkbookPart wbPart = document.WorkbookPart;
  Sheet theSheet = wbPart.Workbook.Descendants<Sheet>().Where(s => s.Name == sheetName).FirstOrDefault();
  WorksheetPart wsPart = (WorksheetPart)(wbPart.GetPartById(theSheet.Id));
  Cell theCell = wsPart.Worksheet.Descendants<Cell>().Where(c => c.CellReference == "D16").FirstOrDefault();
  value = theCell.InnerText;
}

在這里，我正在閱讀包含公式的特定單元格“ D16”。

需要更多幫助，無法讀取該單元格的日期。 我有一些電話。 對於日期單元格，數據類型為Null，因此以下代碼不起作用。 我如何從牢房中獲取日期谷

  if (theCell != null)
                {
                    value = theCell.CellValue.InnerText;
                    if (theCell.DataType != null)
                    {
                        switch (theCell.DataType.Value)
                        {
                            case CellValues.SharedString:
                                var stringTable = wbPart.GetPartsOfType<SharedStringTablePart>().FirstOrDefault();
                                if (stringTable != null)
                                {
                                    value = stringTable.SharedStringTable.ElementAt(int.Parse(value)).InnerText;
                                }
                                break;

                            case CellValues.Boolean:
                                switch (value)
                                {
                                    case "0":
                                        value = "FALSE";
                                        break;
                                    default:
                                        value = "TRUE";
                                        break;
                                }
                                break;
                        }
                    }
                }

Answer 1

嘗試單元格的CellValue屬性。

WorksheetPart wsPart = (WorksheetPart)(wbPart.GetPartById(theSheet.Id));
using(SpreadsheetDocument document = SpreadsheetDocument.Open(fileName, false))
{
  WorkbookPart wbPart = document.WorkbookPart;
  Sheet theSheet = wbPart.Workbook.Descendants<Sheet>().Where(s => s.Name == sheetName).FirstOrDefault();
  WorksheetPart wsPart = (WorksheetPart)(wbPart.GetPartById(theSheet.Id));
  Cell theCell = wsPart.Worksheet.Descendants<Cell>().Where(c => c.CellReference == "D16").FirstOrDefault();
  value = theCell.CellValue;
}

我假設您是出於調試目的對單元格引用進行硬編碼。 否則，我強烈建議不要這樣做。

嘗試這個：

WorksheetPart wsPart = (WorksheetPart)(wbPart.GetPartById(theSheet.Id));
using(SpreadsheetDocument document = SpreadsheetDocument.Open(fileName, false))
{
    WorkbookPart wbPart = document.WorkbookPart;
    Sheet theSheet = wbPart.Workbook.Descendants<Sheet>().Where(s => s.Name == sheetName).FirstOrDefault();
    WorksheetPart wsPart = (WorksheetPart)(wbPart.GetPartById(theSheet.Id));
    Cell theCell = wsPart.Worksheet.Descendants<Cell>().Where(c => c.CellReference == "D16").FirstOrDefault();
    var value = theCell.CellValue.InnerText;
}
