美好的一天,我有一个使用Open XML上传excel文件的MVC应用程序。该文件具有我传递回teh视图的deciml值,但是当我将应用程序转发给teh服务器时,它返回带有前面小数位的值,例如292,28返回为292.27999999999997,而85,7703返回为85.770300000000006。我已尝试在代码中添加数字格式,但它似乎无法正常工作,请参阅下面的代码

在这里,我将我的Excel值映射到我的对象。

 private static CleanSupplierClaim MappExcelOpenXMLtoGenericList(IList<string> rowData, IList<string> columnNames)
    {


        var cleanSupplierClaims = new CleanSupplierClaim()
        {
            Action = rowData[columnNames.IndexFor("Action")],
            Line_Number = rowData[columnNames.IndexFor("Lineno")],
            Total_Claim = rowData[columnNames.IndexFor("TotalClaim")].ToDecimalNullable(), //Convert.ToDecimal(Math.Round(Convert.ToDouble(rowData[columnNames.IndexFor("TotalClaim")].ToDoubleNullable()),2)),
            Currency = rowData[columnNames.IndexFor("Currency")],
            ClaimReference = rowData[columnNames.IndexFor("ClaimReference")]
        };

        return cleanSupplierClaims;
    }

这里我获取单元格值并尝试格式化从文件中获得的十进制类型

private static string GetCellValue(SpreadsheetDocument document, Cell cell)
{
    var culture = new CultureInfo("en-us");
    culture.NumberFormat.CurrencyDecimalDigits = 3;

    if (cell == null) return null;
    string value = cell.InnerText;

    //Process values particularly for those data types.
    if (cell.DataType != null)
    {
        switch (cell.DataType.Value)
        {
            //Obtain values from shared string table.
            case CellValues.SharedString:
                var sstPart = document.WorkbookPart.GetPartsOfType<SharedStringTablePart>().FirstOrDefault();
                value = sstPart.SharedStringTable.ChildElements[Int32.Parse(value)].InnerText.Trim();
                break;

            //Optional boolean conversion.
            case CellValues.Boolean:
                var booleanToBit = ConfigurationManager.AppSettings["BooleanToBit"];
                if (booleanToBit != "Y")
                {
                    value = value == "0" ? "FALSE" : "TRUE";
                }
                break;






                //specifire = "F";
            case CellValues.Number:
                return Convert.ToDecimal(cell.CellValue.Text).ToString(culture);
            default:
                if (cell.CellValue != null)
                    return cell.CellValue.Text;
                return string.Empty;

        }
    }
    return value;
}

我在我的sql数据库中将十进制字段设置为3的小数位,但它仍然返回不正确的十进制值,格式不正确。

关于如何解决这个问题的任何想法,亲切的问候

1 个答案:

答案 0 :(得分:0)

希望这有帮助:

 string stringNumber = "0.1230000";

 decimal decimalNumber = decimal.Parse(stringNumber, CultureInfo.InvariantCulture);//or another culture

 decimal roundedNuber = decimal.Round(decimalNumber, 3);
