我有一个Excel文件,其中单元格C4中的公式为=SUM(C2:C3)。我在单元格C2和C3中分别有数值15和17。从程序上讲,我希望能够执行C4公式并获得值32(即公式的结果)。
有人建议我使用OpenXml SDK。因为这个代码将被Windows Azure Website托管和使用。
这是我的代码目前的情况,但单元格不会执行C4的公式。
string filename = Server.MapPath("/") + "ExcelData.xlsx";
using (SpreadsheetDocument document = SpreadsheetDocument.Open(filename, true))
{
document.WorkbookPart.Workbook.CalculationProperties.ForceFullCalculation = true;
document.WorkbookPart.Workbook.CalculationProperties.FullCalculationOnLoad = true;
Sheet sheet = document.WorkbookPart.Workbook.Descendants<Sheet>().SingleOrDefault(s => s.Name == "myRange1");
if (sheet == null)
{
throw new ArgumentException(
String.Format("No sheet named {0} found in spreadsheet {1}", "myRange1", filename), "sheetName");
}
WorksheetPart worksheetPart = (WorksheetPart)document.WorkbookPart.GetPartById(sheet.Id);
int rowIndex = int.Parse("C4".Substring(1));
Row row = worksheetPart.Worksheet.GetFirstChild<SheetData>().
Elements<Row>().FirstOrDefault(r => r.RowIndex == rowIndex);
Cell cell = row.Elements<Cell>().FirstOrDefault(c => "C4".Equals(c.CellReference.Value));
}
