Question

I am fetching date from textbox and passing it to dateTime by passing it though a function,

BUT it gives me two different results

DateTime Fromdate1 = devTools.ParseDate(datepicker1.Text);

TextBox —>OutPut

02/09/2012 –> 2/9/2012 12:00:00 AM

30/08/2012 –> 8/30/2012 12:00:00 AM

public DateTime ParseDate(string s)
    {
        DateTime result;
        if (!DateTime.TryParse(s, out result))
        {
            string[] formats = { "dd'/'MM'/'yyyy" };
            result = DateTime.ParseExact(s, formats, new CultureInfo("en-US"), DateTimeStyles.None);
            //result = DateTime.ParseExact(s, "dd'/'MM'/'yyyy", System.Globalization.CultureInfo.InvariantCulture);
            //result = result.AddDays(1);
        }
        return result;
    }

What is the problem here,Is there a prper way to get constant output type,also it will create problems in DB since 08/09 will be checked against 09/08 and vice versa !

One more problem in SQL :

Select convert(nchar(10),FromDate, 103) AS FromDate,convert(nchar(10),ToDate, 103) AS ToDate FROM Tbl_PropertyRoomSeasonPrices

OUTPUT :

28/08/2012 | 09/01/2012

dd/mm/yyyy | mm/dd/yyyy
(CORRECT) (WRONG)

but 103 for fromDate and 101 for toDate makes it both same,Why the variations ??

Answer 1

It seems to me that the “problem” here is just how you’re interpreting the output. Your method returns a DateTime – not a string – so when you’ve written. “02/09/2012 –> 2/9/2012 12:00:00 AM” you presumably mean that an input of string “02/09/2012” gives you a result DateTime which happens to have a string representation of “2/9/2012 12:00:00 AM” in whatever way you’re converting it to a string, e.g. by looking in the debugger. That will use the current culture and the default format – but that’s not part of the DateTime value itself.

Look at the properties of the DateTime and you’ll see it’s been parsed correctly.

also it will create problems in DB since 08/09 will be checked against 09/08 and vice versa

No it won’t. Not if you’re doing things properly – using parameterized SQL and specifying the DateTime value for the property. It could well give you problems if you’re including the value directly in your SQL, but that’s a bad idea anyway.
