使用OpenXml SDK 向Excel工作簿单元格中插入公式

函数实现：

private static void FillData(string path, string sheetName)
        {
            using (SpreadsheetDocument document = SpreadsheetDocument.Open(
               path, true))
            {
                // find sheets by sheet name
                IEnumerable sheets = document.WorkbookPart.Workbook.Descendants().Where(s => s.Name == sheetName);
                if (sheets.Count() == 0)
                {
                    // The specified worksheet does not exist.
                    return;
                }
                WorksheetPart worksheetPart = (WorksheetPart)document.WorkbookPart.GetPartById(sheets.First().Id);
                Worksheet worksheet = worksheetPart.Worksheet;
                SheetData sheetData = worksheet.GetFirstChild();
 
                // fill data to Cell F4
                Row row1 = new Row()
                {
                    RowIndex = (UInt32Value)4U,
                    Spans = new ListValue() { InnerText = "5:6" }
                };
                                
                //CellFormula cellformula = new CellFormula();
                //cellformula.Text = "SUM(A1:A2)";
 
                //Cell cell = new Cell()
                //{
                //    CellReference = "F4",
                //    DataType = new EnumValue(CellValues.Number),
                //    CellFormula = cellformula
                //};
 
                Cell cell = new Cell() { CellReference = "E4" };
                CellFormula cellformula = new CellFormula();
                cellformula.Text = "SUM(A1,C5)";
                CellValue cellValue = new CellValue();
                cellValue.Text = "0";
                cell.Append(cellformula);
                cell.Append(cellValue);
 
                Cell cell1 = new Cell() { CellReference = "F4" };
                CellValue cellValue1 = new CellValue();
                cellValue1.Text = "222";
                cell1.Append(cellValue1);
 
                // create formula in E4
                row1.Append(cell);
                // fill data to F4
                row1.Append(cell1);
 
                // fill data to Cell C5
                Row row2 = new Row() { RowIndex = (UInt32Value)5U };
                Cell cell2 = new Cell() { CellReference = "C5" };
                CellValue cellValue2 = new CellValue();
                cellValue2.Text = "111";
                cell2.Append(cellValue2);
                row2.Append(cell2);
 
                // append rows to SheetData elment
                sheetData.Append(row1);
                sheetData.Append(row2);
 
                // save worksheet
                worksheet.Save();
            }
