Question

I am writing a date in xml file & then reading a date from xml file to display.
I have used Datetimepicker which has customFormat= MM/dd/yyyy. & it sets <date>02/29/2001</date> in xmlfile.

while reading if value is "02/02/2001"it reads & shows it perfectly in datetimepicker

but if value is "02/22/2001". edited:

it throws an exception.
String was not recognized as a valid DateTime.

Answer 1

Have you set the cultureinfo of your application to expect the date in a MM/dd/yyyy format? It seems like it is expecting dd/MM/yyyy, that’s why 02/02/2001 works, I suspect 28/02/2001 would work as well.

Edit: Hang on, 2001 was not a leap year, 29/02/2001 will never be a valid date!

Edit: added sample

// C#
// Put the using statements at the beginning of the code module
using System.Threading;
using System.Globalization;
// Put the following code before InitializeComponent()
// Sets the culture to English (US)
Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
// Sets the UI culture to English (US)
Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US");
