使用数字格式的封闭XML导出到excel至特定列

Question

在使用封闭的xml导出到excel时尝试将字符串值转换为数字

//以下行显示无法将字符串转换为IXLNumber格式的错误

ws.Range（“ B2”，“ C5”）。Style.NumberFormat =“＃，## 0.00”;

                var ws = wb.Worksheets.Add(mydatatable, fileName);

                //below line works but without comma separated value
                ws.Range("B2","C5").SetDataType(XLCellValues.Number);

                //below line show error of cannot convert string to IXLNumber format
                ws.Range("B2", "C5").Style.NumberFormat = "#,##0.00";  

                ws.Columns("B").Style.NumberFormat = "[$$-409]#,##0.00";  


                wb.SaveAs(filePath);
