parsing a string with DateTime.ParseExact
-
Hi. I am having trouble parsing a string into the format I want. Basically, I want the string to end up being "MMdd" where MM is the month (with a leading zero if necessary) and dd is the day (with a leading zero if necessary). This is what I have tried: String today = DateTime.Today.Date.ToShortDateString(); String pattern = "MMdd"; DateTime dt_today = DateTime.ParseExact(today, pattern, null); // line 3 today = dt_today.ToString(); Console.WriteLine("today's date is: " + today); The problem is that my program crashes once run. If you look at the third line, in place of null, I have tried sending: System.Globalization.CultureInfo.InvariantCulture, System.Globalization.CultureInfo.CurrentCulture Both yielded the same result. I have also tried using "Now" instead of "Today" in the first line. What am I doing wrong? I'd appreciate any help.

I'd use an overload of the ToString method on the datetime, which allows you to specify the format. This looks like too many steps to take, to me.

Hi, if you want your ParseExact to succeed, today must consist of exactly four digits. So it all depends on your regional settings, which control the outcome of ToShortDateString(). You could try
String today = DateTime.Today.Date.ToString("MMdd");:)Luc Pattyn [Forum Guidelines] [My Articles]

What exactly are you trying to do? Do you already have a
DateTimeobject that you are trying to display in a specific format? If so, you just need to callToStringon that object and pass the format string you want. The code you show takes aDateTimeobject, converts it to a string, and then tries to parse that string and convert it back to aDateTimeobject, which you then callToStringon to turn it back into a string. You can accomplish the same thing by doing this:Console.WriteLine("today's date is: " + DateTime.Today.ToString("MMdd"));Scott.
