Excel 工作表阅读 - ClosedXML - 日期显示为数字

Question

I have an excel sheet which i am trying to parse. All works correctly except when i have a date eg 01-Nov-2016 . When trying to read this value via _value = cell.Value.ToString(); it is returning just a number.

After the sheet has been parsed the value 4426979 is displayed.

When I debug the codebase the cell.Value equals [$-4426979]d-mmm-yy .

has anyone encountered this issue? if so, How do you fix it?

the full Function is:

protected string GetCellContents(IXLCell cell)
{
    string _value = string.Empty;
    if (cell.HasFormula)
    {
        _value = cell.ValueCached.ToString();
    }
    else
    {
        _value = cell.Value.ToString();
    }

    return _value;
}

Answer 1

你试过用 .ToString("dd-MMM-yyyy") 替换 .ToString() 吗？

Answer 2

You can try this:

string strValue = cell.ValueCached.ToString();
double doubleValue = double.Parse(strValue); // or use double.TryParse if you need
DateTime dateTimeValue = DateTime.FromOADate(doubleValue);
_value = dateTimeValue.ToString();
