Parse Datetime string
I'm trying to parse the following DateTime in C#:
string date = "Wed Jul 25 19:41:36 2012 +0200"
DateTime result = DateTime.Parse(date);
And I'm getting the following error:
System.FormatException : String was not recognized as a valid DateTime.
Anybody knows what is the problem here?
You can use DateTime.ParseExact() for that. For example
UPDATED:
string dateString = "Your date";
string format = "ddd MMM dd HH:mm:ss yyyy %K";
DateTime dateTime = DateTime.ParseExact(dateString, format,
CultureInfo.InvariantCulture);
Console.WriteLine(dateTime);
Documentation Here and DateTime string formatting options here.
You can also view here {Complr.com}
You need to specify the parsing format as that is non-standard. DateTime.ParseExact allows you to specify the format.
Something like this will work, however I've yet to verify if that time-zone part is working correctly, seems to give me a date/time at 1800 hrs... Ah this is because where I am it is BST (GMT +1).
static void Main(string[] args)
{
string date = "Wed Jul 25 19:41:36 2012 +0200";
string format = "ddd MMM dd HH:mm:ss yyyy %K";
//string format = "ddd MMM dd HH:mm:ss yyyy zzz"; // Also works.
DateTime dateTime = DateTime.ParseExact(date, format, CultureInfo.InvariantCulture);
Console.ReadLine();
}
DateTime string formatting options are documented here, you can create a parse string using any combination of these to parse a DateTime successfully.

I want to parse dd-MM-yyyy date format into dd MMM yyyy I get the reference but it cannot convert date in a proper manner it mismatches the date and month.
Suppose my date is
string dat = "11-01-2019"
and I am using
string date = DateTime.Parse(dat).ToString("dd MMM yyyy");
but it returns 01 Nov 2019. But actually, it is 11 Jan 2019 because the format of date is dd-MM-yyyy I don't understand how to correct it any method of parsing I am using it returns 01 Nov 2019 that is wrong. Please help me to resolve the issue
You'll need to specify the culture the date is formatted for. I'm assuming UK here:
var ukCulture = System.Globalization.CultureInfo.GetCultureInfo("en-gb");
string dat = "11-01-2019";
string date = DateTime.Parse(dat, ukCulture).ToString("dd MMM yyyy");
Console.WriteLine(date);
Try it online
Note that you'll get a FormatException if you enter an invalid date here, so it might be better to use TryParse:
var ukCulture = System.Globalization.CultureInfo.GetCultureInfo("en-gb");
string dat = "11-01-2019";
DateTime parsedDate;
if (DateTime.TryParse(dat, ukCulture, System.Globalization.DateTimeStyles.None, out parsedDate))
{
string date = parsedDate.ToString("dd MMM yyyy");
Console.WriteLine(date);
}
else
{
Console.WriteLine("invalid date");
}

Adding to John's great answer, here's a list of CultureInfo codes for reference:
http://www.csharp-examples.net/culture-names/
I have a string passed from kendo grid filter as follows,
2018-05-01T18:30:00.000Z
i need to conver the above to this format,
May 05 2018
i tried with the following,
string date = (DateTime.ParseExact(constant.ToString(), "MMM dd yyyy", CultureInfo.InvariantCulture)).ToString("MMM dd yyyy");
bit its not working as expected
The format of the call to DateTime.ParseExact is not the format of the date that you're passing. You could change the format, or call DateTime.Parse directly as that format is recognized by it:
String dateString = "2018-05-01T18:30:00.000Z";
DateTime date1 = DateTime.Parse(dateString);
DateTime date2 = DateTime.ParseExact(dateString, "yyyy-MM-ddTHH:mm:ss.fffZ", null);
Console.WriteLine(date1.ToString("MMM dd yyyy"));
Console.WriteLine(date2.ToString("MMM dd yyyy"));
All you need is the following. And please note that the datetime string actually represents May 1 2018, not May 5 2018 as mentioned in the question.
var d = DateTime.Parse("2018-05-01T18:30:00.000Z");
Console.WriteLine(d.ToString("MMM dd yyyy"));
Im making a post from a view and getting it in a actionresult as a string.
The value I get is:
Tue Feb 18 2014 00:00:00 GMT-0300 (Hora oficial do Brasil)
Using DateTime.Parse throws an exception:
String was not recognized as a valid DateTime.
What makes this string invalid, and how can I successfully convert it to a DateTime?
DateTime.Parse throws exception for this string because it does not have a standart date/time format.
If your GMT-0300 (Hora oficial do Brasil) is stable in your string, you can use;
var s = "Tue Feb 18 2014 00:00:00 GMT-0300 (Hora oficial do Brasil)";
var date = DateTime.ParseExact(s,
"ddd MMM dd yyyy HH:mm:ss 'GMT'K '(Hora oficial do Brasil)'",
CultureInfo.InvariantCulture);
Console.WriteLine(date);
Output will be;
2/18/2014 12:00:00 AM
Here is a demonstration.
I don't think there is a way to parse your (Hora oficial do Brasil) part except using string delimiter.
Take a look at;
The "K" Custom Format Specifier
I don't know why K specifier doesn't work on Ideone actually. I have to put -0300 part also as a string delimiter for generating example. It can be an issue with DateTimeKind enumeration but I'm not sure..
The string is invalid because of the 'GMT' and the '(Hora oficial do Brasil)' parts.
Simply put: the parser is unable to determine what is part of a date time and what is not.
By using format strings you will be able to parse the string into the DateTime format.
see: MSDN: Custom Date and Time Format Strings
in your case this format string will work: "ddd MMM dd yyyy hh:mm:ss 'GMT'K '(Hora oficial do Brasil)'".
You can use it like this:
string input = "Tue Feb 18 2014 00:00:00 GMT-0300 (Hora official do Brasil)";
string[] format = { "ddd MMM dd yyyy hh:mm:ss 'GMT'K '(Hora official do Brasil)'" };
DateTime date;
if (DateTime.TryParseExact(input, format, CultureInfo.InvariantCulture, DateTimeStyles.None, out date))
{
//Yepee the input was parsed correct
}
else
{
//system was unable to parse the string
}
Or like this if error handling is not nessesary:
string input = "Tue Feb 18 2014 00:00:00 GMT-0300 (Hora official do Brasil)";
string format = "ddd MMM dd yyyy hh:mm:ss 'GMT'K '(Hora official do Brasil)'";
DateTime date = DateTime.ParseExact(input, format, CultureInfo.InvariantCulture);
How to convert "yyyy-MM-ddTHH:mm:ss" into "dd MMM yyyy" format? For Instance, i want to convert 2013-04-16 05:30:05 into 16 April 2013. What is the correct method to achieve this?
First ParseExact then do ToString (I assume that you have string object, if you have DateTime object, skip first line)
var dateTime = DateTime.ParseExact(yourDateString, "yyyy-MM-ddTHH:mm:ss", CultureInfo.InvariantCulture);
var yourNewString = dateTime.ToString("dd MMM yyyy");
Note that representation of DateTime you see in debugger is dependant on your current culture.
First, a DateTime has no format. But if you've already a string that represents a DateTime with the format yyyy-MM-ddTHH:mm:ss and you want to convert it to a string-date with format dd MMM yyyy you need to parse it to DateTime first.
Therefore use DateTime.ParseExact:
DateTime dt = DateTime.ParseExact("2013-04-16 05:30:05", "yyyy-MM-dd HH:mm:ss", null);
Now you can use DateTime.ToString:
string result = dt.ToString("dd MMM yyyy");
Note that you need to pass a different CultureInfo object to ParseExact/ToString if you want to parse with another DateTimeFormat than your current (f.e. force english month names instead of german: dt.ToString("dd MMM yyyy", CultureInfo.InvariantCulture)).
As others mentioned, a DateTime has no format. To parse a string literal to a Date you need to call DateTime.Parse (if the string is in a culture-specific format) or DateTime.ParseExact if you need to pass a format string.
The format can be a custom format like yyyy-MM-dd HH:mm:ss or one of the standard format strings, eg. s for yyyy-MM-ddTHH:mm:ss.
2013-04-16 05:30:05 it not in one of the standard formats, so you have to parse by passing a custom format string:
var dt = DateTime.ParseExact("2013-04-16 05:30:05", "yyyy-MM-dd HH:mm:ss", null);
On the other hand, yyyy-MM-ddTHH:mm:ss is the s standard format so you can just write:
var dt = DateTime.ParseExact("2013-04-16T05:30:05", "s", null);
I have a source where dates comes in this string form:
Sat Sep 22 13:15:03 2018
Is there an easy way I can parse that into a DateTime in C#? I've tried with DateTime.(Try)Parse, but it doesn't seem to recognize this specific format...
You should prefer DateTime.ParseExact and TryParseExact; these methods let you specify the expected format(s) in your program.
The DateTime.Parse and TryParse methods are dangerous because they accept the current date/time format configured on the machine where the code is running -- which the user can change from the default -- along with a couple of culture-neutral formats. In other words, the user can change settings in Control Panel and break Parse/TryParse.
This works:
DateTime dt = DateTime.ParseExact ("Sat Sep 22 13:15:03 2018", "ddd MMM d HH:mm:ss yyyy", null)
Try DateTime.ParseExact
This code takes your date string and applies a format to create a DateTime object.
CultureInfo provider = CultureInfo.InvariantCulture;
string dateString = "Sat Sep 22 13:12:03 2018";
string format = "ddd MMM dd HH':'mm':'ss yyyy";
DateTime result = DateTime.ParseExact(dateString, format, provider);
var str = "Sat Sep 22 13:15:03 2018";
var date = DateTime.ParseExact(str, "ddd MMM dd HH:mm:ss yyyy", CultureInfo.InvariantCulture);
