Hello all,

Is there a default or easy way in C# to convert a string which has this
format DDMMYYYYHHNN convert to a DateTime ?

Thanks,

Peter.
 
This code snippet should work for you:

DateTime date = DateTime.ParseExact(t, "ddMMyyyyHHmm",
System.Globalization.CultureInfo.InvariantCulture)

DateTime d = DateTime.ParseExact(input, "ddMMyyyyhhmm", null);

Thanks Sergey !

It works but with a little strange result - a little example to show : (see
inside the code)
Is there a explanation for this strange result ?

Regards,
Peter.

It should work with the ParseExact method

DateTime mydatetime =
Datetime.ParseExact(sourcestring,"ddMMyyyyyHHmm",Thread.CurrentThread.CurrentCulture)
I assume HHNN means hours and minutes in 24 hours style

Thanks Norbert,

C# doesn't recognize Thread.CurrentThread.CurrentCulture ?
Is this not in the CF ? Or am I doing something wrong ?

Regards,
Peter.
 
Just tested it, the result for dt.Hour was 12, as expected. The only one
thing I've changed in your code:

"ddMMyyyyhhmm" => ddMMyyyyHHmm (see my previous post)

Also before pass that value to WinCESetSystemTime don't forget to call
ToUniversalTime.
