I am trying to convert the string value in the date time. I know this question was asked so many times. But I checked mostly all the answers. But I didn't get answer for my problem.
Following is my code:
string ObjTime = "5/4/2013 10:30 PM";
DateTime d = DateTime.ParseExact(ObjTime, "dd/MM/yyyy H:mm", CultureInfo.CurrentCulture);
I have also checked by chenging my System datetime format.
And also I have use this:
DateTime d = DateTime.ParseExact(ObjTime, "d/M/yyyy H:mm tt", CultureInfo.CurrentCulture);
Can any one please help me to solve this problem?
And also I have check by changing the format as d/m/yyy H:mm but still it is giving me error. I am using Visual Studio 2012.
I checked the problem and it seems like your string is not in correct format hence the ParseExact is throwing error.
If you change your string from
string ObjTime = "5/4/2013 10:30 PM";
to
string ObjTime = "05/04/2013 10:30 PM";
The code works
Also checked this
Your string has day and month in single digit, and you are trying to parse it with format which supports only double digits day/month
You should do:
string ObjTime = "5/4/2013 10:30 PM";
DateTime d = DateTime.ParseExact(ObjTime, "d/M/yyyy h:mm tt", CultureInfo.CurrentCulture);
You should use single d and M, which would support single digit and double digit day/month for parsing.
You should also use lower case h since you have PM in the string. So your final format should be "d/M/yyyy h:mm tt"
Instead of specifying the format string explicitly, you can try specifying the culture, in which this format is valid. For EN-US culture:
DateTime.Parse(ObjTime, CultureInfo.GetCultureInfo("en-us"));

I'm parsing date from server, date is in this format 6/16/2016 3:15:29 PM Could you help me please convert date to 2016-06-16?
I tried:
DateTime date = DateTime.ParseExact(datestring, "MM/dd/yyyy h-m-s t", System.Globalization.CultureInfo.InvariantCulture);
string formattedDate = date.ToString("yyyy-MM-dd")
but it's giving me error.
You've got 3 problems
You're not using the correct time separators
You're using only one t when you need two
You're using two M when you only need one
Try
DateTime date = DateTime.ParseExact(datestring, "M/d/yyyy h:m:s tt", System.Globalization.CultureInfo.InvariantCulture);
string formattedDate = date.ToString("yyyy-MM-dd");
The reason you need only one M is because MM expects a leading zero. Since the values of the date and time are delimited it's better to use the single versions for month, day, minutes, and seconds because they will work for values with or without leading zeros.
To execute DateTime.ParseExact() format of the input string and the format string must be the same. try this:
DateTime date = DateTime.ParseExact(datestring, "M/dd/yyyy h:mm:ss tt", System.Globalization.CultureInfo.InvariantCulture);
string formattedDate = date.ToString("yyyy-MM-dd");
These are interesting in the given input string(6/16/2016 3:15:29 PM):
The month is represented in single digit so it should be M instead for MM. We use MM if it is specified as 06.
Same in the case of Hours too. It should be h instead for normal hh
There is a single space in between Date and Time as well as Time and PM.
So we must consider all of these while generating the Format-string for ParseExact
I have one object {System.DateTime} value is {5/17/2010 12:00:00 AM}.
I want to convert this datetime format to "d-MMM-yyyy",
string msStartDt="5/17/2010 12:00:00 AM";
DateTime.ParseExact(msStartDt, "MM/dd/yyyy HH:mm:ss",CultureInfo.InvariantCulture).ToString("d-MMM-yyyy");
String was not recognized as a valid DateTime.
second parameter of ParseExac() method is a format specifier that defines the required format of msSartDt.
If I change {5/17/2010 12:00:00 AM} to {17-Dec-2010 12:00:00 AM} we need to change 2nd parameter of DateTime.ParseExact()
My question is how we can find programatically the format of msStartDt so we can put in second parameter of DateTime.ParseExact() method.
You need to use
M specifier instead of MM specifier since single digit numbers don't have leading zero
hh specifier instead of HH specifier since you are using 12-hour format
tt specifier for AM/PM designators
string msStartDt = "5/17/2010 12:00:00 AM";
var str = DateTime.ParseExact(msStartDt, "M/dd/yyyy hh:mm:ss tt",
CultureInfo.InvariantCulture).ToString("d-MMM-yyyy");
On the other hand, your question is vauge. You said I have one object DateTime value is 5/17/2010 12:00:00 AM but you have a string in your code as it.
If you have already a DateTime, you just need to format it with ToString method. You don't need parsing at all.
DateTime dt = ...
var str = dt.ToString("d-MMM-yyyy", CultureInfo.InvariantCulture);
My question is how we can find programatically the format of msStartDt
so we can put in second parameter of DateTime.ParseExact() method.
It is not possible.
Think about you have a string like 01/02/2015. What is the proper format of this string? It is 1st February or 2nd January? Is it dd/MM/yyyy or MM/dd/yyyy? It is totally ambiguous as you can see. If you have a string formatted, you have to know it's proper format to parse a DateTime.
You need to specify AM/PM in your string format:
DateTime.ParseExact(msStartDt, "M/dd/yyyy hh:mm:ss tt",CultureInfo.InvariantCulture)
also you need to change from HH to hh because HH is for 24h dates
Here you have all datetime fromat constants.
Please try this one:
DateTime.ParseExact(msStartDt, "M/dd/yyyy hh:mm:ss tt",CultureInfo.InvariantCulture);
When we use the ParseExact the format of the string we parse must be exactly the same with the string. In your case you had omitted the AM/PM designator. Furthermore you need to correct the months and hours. For futher information, please have a look here.
You should specify the correct parse format
DateTime.ParseExact(msStartDt, "M/d/yyyy h:mm:ss tt", CultureInfo.InvariantCulture).ToString("d-MMM-yyyy")
Firstly, convert your specified date from String to DateTime, then convert to another date format:
string dateString;
CultureInfo provider = CultureInfo.InvariantCulture;
dateString = "05/17/2010 12:00:00 AM";
DateTime dt = Convert.ToDateTime(dateString, provider);
Console.WriteLine(dt.ToString("d-MMM-yyyy HH:mm:ss tt"));
See other date time formats in the following link: http://www.csharp-examples.net/string-format-datetime/
Your output should be like the follow screenshot:
I have two Timestamps that are saved to and read from two XML files.
Currently I am reading the timestamps from the xml files in a WCF Service method, so they are coming in as Strings , but I need them to be converted into DateTime so they can be compared.
The obvious Convert.ToDateTime(TimeStampString) renders this error at Runtime -
String was not recognized as a valid DateTime
As does
DateTime.ParseExact(TimeStampString, "mm/dd/yyyy hh:MM:ss", CultureInfo.InvariantCulture);
Both Timestamps are in the correct format for DateTime (mm/dd/yyyy hh:MM:ss).
I've even tried splitting the timstamp strings into String[] and assembling my own DateTime object by hand, and I still received the error.
Is this a format issue? How can I make my String a valid DateTime?
It's a format issue
mm/dd/yy hh:MM:ss
should be
MM/dd/yyyy hh:mm:ss
(basically, swap the upper case MM in the date & the lowercase mm in the time)
I resolved the issue by removing any attempts to alter the format from US, so Strings came in with US format - then used an IFormatProvider to alter the format at conversion time.
IFormatProvider localFormat = new System.Globalization.CultureInfo("fr-FR", true);
DateTime ContentLastUpdatedTime = DateTime.Parse(ContentLastUpdatedStamp, localFormat , System.Globalization.DateTimeStyles.AssumeLocal);
DateTime ContentLastGrabbedTime = DateTime.Parse(LastGrabbedTimeStamp, localFormat , System.Globalization.DateTimeStyles.AssumeLocal);
You need to use
DateTime.ParseExact(TimeStampString, "MM/dd/yyyy hh:mm:ss", CultureInfo.InvariantCulture);
instead of
DateTime.ParseExact(TimeStampString, "mm/dd/yyyy hh:MM:ss", CultureInfo.InvariantCulture);
The issue is lower case mm which is used for minutes, You need MM upper case MM, plus your date is in 24 hours format, and you need upper case HH for hour part , so your format should be:
MM/dd/yyyy HH:mm:ss
(considering you have yyyy in your original code based on your comment)
See: Custom Date and Time Format Strings
Here you go
var dtedatetime = DateTime.Now.ToString("yyyy-MM-ddTHH:mm:sszzz");
DateTimeOffset dto;
bool bIsParsed = DateTimeOffset.TryParseExact(dtedatetime , "yyyy'-'MM'-'dd'T'HH':'mm':'sszzz",
System.Globalization.CultureInfo.InvariantCulture,
DateTimeStyles.AdjustToUniversal, out dto);
var result = dto.DateTime;
I have been trying many different solutions found here but none works. I want to convert the string to the format of dd/MM/yyyy
editField["ExpiryTime"] = "5/19/2011 12:00:00 AM";
DateTime dt = DateTime.ParseExact(editField["ExpiryTime"].ToString(), "dd/MM/yyyy HH:mm:ss tt", CultureInfo.InvariantCulture);
But I always get an error of invalid System.DateTime. Pleaes help!
Use CultureInfo.InvariantCulture to avoid culture issues like invalid date separators and this format:
M/dd/yyyy hh:mm:ss tt
Uppercase M is for months, dd are the days, yyyy the four digit years. Lowercase hh are the hours in 12h format(required in combination with AM/PM), mm are the minutes, ss the seconds and tt the AM/PM designator.
string input = editField["ExpiryTime"].ToString(); // "5/19/2011 12:00:00 AM"
DateTime dt = DateTime.ParseExact(input, "M/dd/yyyy hh:mm:ss tt", CultureInfo.InvariantCulture);
I want to convert the string to the format of dd/MM/yyyy
Then use ToString in the same way, CultureInfo.InvariantCulture forces / as date separator, without it will be replaced with your current culture's date-separator:
string result = dt.ToString("dd/MM/yyyy", CultureInfo.InvariantCulture);
If you need it as string, then you should try this
var dt = string.Format("{0:dd/MM/yyyy}",DateTime.Now);
Note: Also check your local system date time format. If it mismatches with the used one , still you might experience the same exception..
I want to convert a String to Datetime. I'm getting an error This is not a valid datetime.
The string I want to convert and code are as follows.
string date1 = "9/13/2012 5:26:06 PM";
TimePart = DateTime.ParseExact(date1, "M/d/yyyy HH:mm:ss tt", System.Globalization.CultureInfo.InvariantCulture);
I think it should be M/dd/yyyy h:mm:ss tt in your format parameter.
It looks like your format is really M/d/yyyy h:mm:ss tt. The difference is h (12-hour, with only as many digits as needed) instead of HH (24-hour, with leading 0 to pad to 2 digits).
If the input format can vary at all, you should use DateTime.Parse instead so that you don't have to tell it the exact format. ParseExact is faster, and requires that it matches the specified format, which may be preferable in your cast.
You need to use the lowercase h:
DateTime TimePart = DateTime.ParseExact(
date1,
"M/d/yyyy h:mm:ss tt",
CultureInfo.InvariantCulture);
Console.WriteLine(TimePart); // 09/13/2012 17:26:06
Uppercase "H" is 24-hour time, lowercase "h" is 12-hour time with AM/PM.
You should be using a lower case h for a 12 hour clock (since you have an AM/PM designator).
Additionally, you should only use one h, as you don't have a leading 0 to the hours, and hh expects it.
A format string that works:
"M/d/yyyy h:mm:ss tt"
It looks like the HH isn't matching the "5". Try h.
