Tryparseexact
trying to parse a date string into a DateTime variable. I've found out that ParseExact is the way to do it, but I try this I get the error: String was not recognized as a valid DateTime. string timeFormat = "dd-MM-yyyy hh:mm:ss"; DateTime startDate = DateTime.ParseExact(reader["startdate"].ToString(), timeFormat, CultureInfo.InvariantCulture); DateTime nextDate = DateTime.ParseExact(reader["nextdate"].ToString(), timeFormat, null); I've tried both with null (which happens to work on another page), and the CultureInfo.InvariantCulture. reader["startdate"].ToString() output: datetime format in c# 01-08-2012 15:39:09 and reader["nextdate"].ToString() output: 01-08-2012 15:39:09 I think it should work, but it doesn't. Somebody have an idea what is wrong? :) c# asp.net parsing datetime share|improve this question edited Aug 1 '12 at 19:32 Luke Hutton 4,18831941 asked Aug 1 '12 at 19:18 DesignMonkeyDK 73116 add a comment| 4 Answers 4 active oldest votes up vote 26 down vote accepted You're using hh in your format string. That's a 12-hour "hour of day" field. The value 15 isn't in range... You want HH instead, which is the 24-hour specifier. See the MSDN custom date and time format strings documentation for more information. share|improve this answer answered Aug 1 '12 at 19:19 Jon Skeet 898k48665147452 Ofcourse. So when I said it worked on another page, I was just lucky it was before 12 last time I tested. But this works. Thank you very much! :) –DesignMonkeyDK Aug 1 '12 at 19:26 And pretty fast answer btw. I cant even accept the the answer yet :) –DesignMonkeyDK Aug 1 '12 at 19:27 add a comment| up vote 1 down vote Most probably due to the difference between your Server locale and the UI locale One easier method will be to specify the globalization details in the web.config like here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us Learn more about Stack Overflow the company Business Learn more about hiring developers or posting ads with us Stack Overflow Questions Jobs Documentation Tags Users Badges Ask Question x Dismiss Join the Stack Overflow Community Stack Overflow is a community of 4.7 million programmers, just like you, helping each other.

Join them; it only takes in c# a minute: Sign up DateTime.ParseExact FormatException String was not recognized as a valid DateTime up vote 5 down vote favorite I'm completely stumped on this one. As far as I can see the documentation and other posts on SO I've read say this should work. I must be missing something silly, but I just cannot see it. I get a FormatException with datetime.parse gives error the message "String was not recognized as a valid DateTime." on the following line of code: return DateTime.ParseExact(value, DateFormat, null, DateTimeStyles.AllowWhiteSpaces | DateTimeStyles.AssumeUniversal); value is "11/04/2013" DateFormat is "dd/MM/yyyy" The current culture is en-GB I've tried various variants of DateTimeStyles but to no effect. My original intent was for the format ddd, dd/MMM/yyyy but that didn't work either (the value in that instance was Tue, 30/Apr/2013) I've also tried forcing the culture to en-GB by passing in new CultureInfo("en-GB") instead of the null I also extracted the code into its own console application to see if there was different about the environment (ASP.NET MVC 3) using System; using System.Collections.Generic; using System.Globalization; using System.Linq; using System.Text; namespace ConsoleApplication2 { class Program { static void Main(string[] args) { var DateFormat = "dd/MM/yyyy"; var value = "30/04/2013"; var culture = new CultureInfo("en-GB"); var result = DateTime.ParseExact(value, DateFormat, culture, DateTimeStyles.AllowWhiteSpaces | DateTimeStyles.AssumeUniversal); Console.WriteLine("\"{0}\" as \"{1}\" ==> {2}", value, DateFormat, result); Console.ReadKey(); } } } And that still gives me the same error. c# .net-4.0 share|improve this question asked Apr 9 '13 at 11:07 Colin Mackay 11.9k SQL Server 2014 Express resources Windows Server 2012 resources Programs MSDN subscriptions Overview Benefits Administrators Students Microsoft Imagine Microsoft Student Partners ISV Startups TechRewards Events Community Magazine Forums Blogs Channel 9 Documentation APIs and reference Dev centers Retired content Samples We’re sorry.

You've added a space between "Oct" and "23", and removed one between your milliseconds and your AM/PM specifier. You'll need to create an array of possible formats using the format guidelines on MSDN. Then you'll pass that array into the DateTime.ParseExact method. If you have a string that's in the wrong format, you'll get this error. Since you've added a space between "oct" and "23", and removed the space between your milliseconds and your AM/PM specifier, you'll have to add the space between the month specifiers and the date specifiers in your format string, and remove the one between the millisecond and AM/PM specifier. MMMdd yyyy hh:mm:ss:fff ttIt's now:MMM dd yyyy hh:mm:ss:fffttYou can handle both like this:string formats = { "MMMdd yyyy hh:mm:ss:fff tt", "MMM dd yyyy hh:mm:ss:ffftt" };DateTime date = DateTime.ParseExact(str, formats, CultureInfo.InvariantCulture, DateTimeStyles.None);Does this clear it up for you?David Morton - http://blog.davemorton.net/ Marked as answer by Prakash4 Monday, November 17, 2008 7:16 PM Monday, November 17, 2008 7:12 PM Moderator All replies 0 Sign in to vote Use DateTime.ParseExact:DateTime date = DateTime.ParseExact(str, "MMMdd yyyy hh:mm:ss:fff
