ObjectDataSource fails to parse string to DateTime

问题

I have a textbox with value that stores ValidFrom form value:

31.01.2012

and cultures set to:

<globalization culture="en-GB" uiCulture="en-GB"/>

in web.config.

And now, ObjectDataSource update method:

    public static void UpdateLac(int id, DateTime ValidFrom)
    {
        /// ...
    }

fails as I get exception that string cannot be parsed. However date in format dd.mm.yyyy (31.01.2012) is valid en-GB format and can be parsed (as far as I know). I have tested it with following code:

            DateTimeFormatInfo dtfi = CultureInfo.CreateSpecificCulture("en-GB").DateTimeFormat;
            var date = DateTime.Parse("31.01.2012", dtfi);
            Console.Write(date.ToLongDateString());

So how come that ObjectDataSource internal conversion fails to convert string (31.01.2012) to DateTime in this example?

回答1:

As far as I know the culture info is loaded directly from the OS ( in this case windows), you can check on your regional setting for the format specified. This is a screenshot from my pc:

As you can see the format for short date is: dd/MM/aa, so maybe there is something going on with your server regional settings or the input should be: 31/01/12 instead of 31.01.2012

Hope this helps.
