Hello,

I am trying to convert a string representation of a date in the format of yyyymmdd to a DateTime.

I'm trying to use inbuilt methods rather than write something custom.

Am I missing something very easy here (quite possible)?

Appreciate any replies.

Here is one way to do it:

            DateTime dt;
            string InputDateString = "20040421";

            int theYear = System.Convert.ToInt32(InputDateString.Substring(0 ,4));
            int theMonth = System.Convert.ToInt32(InputDateString.Substring(4 ,2));
            int theDay = System.Convert.ToInt32(InputDateString.Substring(6 ,2));


            dt = new DateTime(theYear, theMonth, theDay);

            Console.WriteLine(dt.Date);
            Console.Write(dt.Month+" "+dt.Day+", "+dt.Year);
            Console.ReadLine();

HTH,

Will

Sorry, should have replied to myself earlier. My original code was failing because my time string was 95900 (meaning 9am and 59mins). I couldn't figure out why the DateTimeFormat below wasn't working. Have since resorted to appending a 0 on the front of any single digit hour - and then my code works as follows:

String date = "20041414 095900";
String DateTimeFormat = "yyyyMMdd Hmmss";
DateTime.ParseExact(date, DateTimeFormat, DateTimeFormatInfo.InvariantInfo,
DateTimeStyles.AllowLeadingWhite|DateTimeStyles.Al lowTrailingWhite);


Thanks for the response.

ParseExact method will allow you to specify the exact format of your date string to use for parsing. It is good to use this if your string is always in the same format.

string iString = "2005-05-05 22:12 PM";
DateTime oDate = DateTime.ParseExact(iString, "yyyy-MM-dd HH:mm tt", System.Globalization.CultureInfo.InvariantCulture) ;


The CultureInfo.InvariantCulture property is neither a neutral nor a specific culture. It is a third type of culture that is culture-insensitive. It is associated with the English language but not with a country or region.
