DateTime constraint on route with time?

Question

How would a constraint for a route look like that needs to be in the format:yyyy-MM-dd hh:mm?

especially with the space there?

I got @"\d{4}-\d{2}-\d{2}" so far, but not sure about the rest

How's it done?

You can ensure the format with the regex, but you probable want to ensure that the datetime is valid. You can try DateTime.TryParseExact

Something like that:

public static bool IsDateValid(string s)
{
    DateTime d;
    return DateTime.TryParseExact(s, "yyyy-MM-dd hh:mm",null,System.Globalization.DateTimeStyles.None,out d);
}

Nothing to do with the question – Jan Jongboom Dec 17 '09 at 14:20
Using regex matching is the only way to create validation for your data? "How would a constraint for a route look like that needs to be in the format:yyyy-MM-dd hh:mm?" – Svetlozar Angelov Dec 17 '09 at 14:24
He wants to create an asp.net-mvc route, which is based on regex matching your url to redirect the request to a handler. – Jan Jongboom Dec 17 '09 at 14:28

The easy way would be

@"\d{4}-\d{2}-\d{2} \d{2}:\d{2}"

But that wont guarantee that its indeed a Date Time Value, you will have to re-check post binding, maybe with Angelov answer.

The other thing to notice is that your URL will get an ugly %20 for the space.
