I am trying to convert a string (which represents date in invariantCulture) to dateTime in given culture. The problem is that when the date is converted to German culture, the day becomes month and month becomes day.
What is wrong with below code or am i missing something ?
var day = 11; var month = 12; var year = 2014;
var someDate = new DateTime(year, month, day);
var theDay = someDate.Day;//11 ok as expected
var theMonth = someDate.Month; //12 ok as expected
var dateString = someDate.ToString(CultureInfo.InvariantCulture);
var date1 = DateTime.Parse(dateString, CultureInfo.GetCultureInfo("de-De"));
var day1 = date1.Day;//12 this should be 11 ?
var month1 = date1.Month; //11 this should be 12 ?
The second argument to DateTime.Parse is used to tell the parser what format the string is in, not what format you want to convert it to. You are generating an invariant string and then parsing it as a German string which is why your day and month are getting swapped.
If your goal is to get a German string representation of the date, just use var dateString = someDate.ToString(CultureInfo.GetCultureInfo("de-DE")).
I guess de-De culture doesn't have a standard date and time format as MM/dd/yyyy HH:mm:ss.
Since you using DateTime.ToString() method with InvariantCulture, result string will be "G" standard format which is MM/dd/yyyy HH:mm:ss for InvariantCulture.
Because of that, dateString will be 12/11/2014 00:00:00 and de-DE culture doesn't have a standard date and time format MM/dd/yyyy HH:mm:ss but has dd/MM/yyyy HH:mm:ss which is dd.MM.yyyy HH:mm:ss for de-DE culture.
That's why DateTime.Parse method matches pattern which is dd/MM/yyyy HH:mm:ss (since it's DateSeparator is . it should be dd.MM.yyyy HH:mm:ss format).
That's why it parses your 12 as a Day and 11 as a Month.
If you already a DateTime (which you have) just use .ToString() method with your de-DE culture like;
var culture = new CultureInfo("de-De");
var dateString = someDate.ToString(culture);
Remember, a DateTime doesn't have any implicit format or culture. It just have date and time values. String representations of them can have formats.
By the way, you can find all standard date and time patterns your de-DE culture like;
var culture = new CultureInfo("de-De");
foreach (var format in culture.DateTimeFormat.GetAllDateTimePatterns())
{
Console.WriteLine(format);
}
Change the following line and test it again:
var dateString = someDate.ToString(CultureInfo.InvariantCulture);
to:
var dateString = someDate.ToString("O");
or:
var dateString = someDate.ToString("S");
ok, here is what i think what you want to accomplish, not sure if i got you right: you want to read an invariant cultured date string and convert it to a german cultured date string.
but in your example you are trying to parse an invariant cultured date AS a german cultured date. of course that leads to a misinterpretation. try this:
string invariantCultureDateString = "12/11/2014 00:00:00";
var dateTime = DateTime.Parse(invariantCultureDateString, CultureInfo.InvariantCulture);
string germanCultureDateString = dateTime.ToString(CultureInfo.GetCultureInfo("de-De"));

I am getting a date time from a URL as string and convert it to Date Time format
I get this exception
Input string was not in correct format
And this is my code that i tried
string time = expiredorno;
var result = Convert.ToDateTime(time);
string timeleft = result.ToString("dd/MM/yyyy HH:mm:ss tt", CultureInfo.CurrentCulture);
Note: in the code The variable 'expiredorno' have this value "2021/05/03 14:54:14 PM"
The input string format is likely invalid under the default culture settings. You could set the culture for the convert method as specified here:
https://learn.microsoft.com/en-us/dotnet/api/system.convert.todatetime?view=net-5.0#System_Convert_ToDateTime_System_String_
CultureInfo culture = new CultureInfo("en-US");
Convert.ToDateTime(time, culture);
string time = "2021/05/03 14:54:14 PM";
var result = Convert.ToDateTime(time, CultureInfo.InvariantCulture);
string timeleft = result.ToString("dd/MM/yyyy HH:mm:ss tt", CultureInfo.InvariantCulture);
We can try adding CultureInfo.InvariantCulture.
We can use one of the proper parse methods from the DateTime Struct (System) | Microsoft Docs https://learn.microsoft.com/en-us/dotnet/api/system.datetime?view=netframework-4.7.2
I have a project that contain 3 string variables.
DateFormatStr is the format string I need to use to output dates.
DateFormatFrom is the start date a request will apply from
FilloutDateTo is the end date the request will apply to.
The problem is that I don't want to manually specify the dates. As you can see in my example below (a working example), I need to specify the dates, but is there a way to make it that the from date has time 00:00:00 and the end date has time 23:59:59?
string DateFormatStr = "MM/dd/yy hh:mm:ss tt";
string DateFormatFrom = "12/04/14 00:00:00";
string FilloutDateTo = "12/04/14 23:59:59";
So I would like to the system time to recognize the from date and the start date respecting the formatStr variable.
Thanks
If I understand correctly, you can use DateTime.Today property like;
var dt1 = DateTime.Today;
var dt2 = DateTime.Today.AddDays(1).AddSeconds(-1);
and use DateTime.ToString() to format them like;
var DateFormatFrom = dt1.ToString("MM/dd/yyyy HH:mm:ss", CultureInfo.InvariantCulture);
var FilloutDateTo = dt2.ToString("MM/dd/yyyy HH:mm:ss", CultureInfo.InvariantCulture);
Results will be;
12/04/2014 00:00:00
12/04/2014 23:59:59
You used hh format specifier but it is for 12-hour clock. Use HH format specifier instead which is for 24-hour clock. And since your result strings doesn't have any AM/PM designator, you don't need to use tt format specifier.
In C# 6.0 you can use string interpolation in order to display formatted dates.
DateTime startOfDay = DateTime.Today;
DateTime endOfDay = DateTime.Today.AddDays(1).AddTicks(-1);
string dateFormatFrom = $"{startOfDay: MM/dd/yy hh:mm:ss tt}";
string filloutDateTo = $"{endOfDay: MM/dd/yy hh:mm:ss tt}";
string idate = "01/11/2019 19:00:00";
DateTime odate = Convert.ToDateTime(idate);
DateTime sdate1 = DateTime.Parse(idate);
string outDate1 = String.Format("{0}/{1}/{2}", sdate1.Day, sdate1.Month,sdate1.Year);
Console.WriteLine(outDate1);
Why this line of code sometimes throws System.FormatException?
DateTime d = DateTime.ParseExact("01.07.2014", "dd/MM/yyyy", CultureInfo.InvariantCulture);
Because your string and format doesn't match.
From documentation;
Converts the specified string representation of a date and time to its
DateTime equivalent using the specified format and culture-specific
format information. The format of the string representation must match
the specified format exactly.
Use dd.MM.yyyy format instead.
DateTime d = DateTime.ParseExact("01.07.2014",
"dd.MM.yyyy",
CultureInfo.InvariantCulture);
Here a demonstration.
Remember, "/" custom format specifier has a special meaning in custom date and time formats. It means as; replace me with the current culture date separator.
In your profile, it says you are from Azerbaijan. That means your CurrentCulture is probably az-Cyrl-AZ (Cyrillic, Azerbaijan) or az-Latn-AZ (Latin, Azerbaijan).
Actually, doesn't matter which culture you use on this case because both culture has . as a DateSeparator property.
That means your original code also works with your CurrentCulture.
DateTime d = DateTime.ParseExact("01.07.2014",
"dd/MM/yyyy",
CultureInfo.CurrentCulture);
// or you can use null
For more information, take a look;
Custom Date and Time Format Strings
You need a culture where "." is the DateSeparator, for example:
DateTime d = DateTime.ParseExact("01.07.2014", "dd/MM/yyyy",
CultureInfo.GetCultureInfo("az-Cyrl-AZ"));
if you are in Azerbaijan and use Azerbaijani language with the Cyrillic script.
You can use:
DateTime d = DateTime.ParseExact("01.07.2014", "dd/MM/yyyy",
null);
to just take the current culture.
Maybe you just need "d" instead of the verbose "dd/MM/yyyy", since the standard short date format in Azerbaijani is just like "01.07.2014".
The "invariant culture" uses "/" as its DateSeparator, so therefore you should not use it in your case.
Also, this works:
DateTime d = DateTime.ParseExact("01.07.2014", "dd/MM/yyyy",
new DateTimeFormatInfo { DateSeparator = ".", }
);
because new DateTimeFormatInfo() makes a read/write "invariant-culture" date/time info for which you can change the relevant property.
The / in the date format will match the date separator of the culture that you specify. If you use a culture that has period as date separator, the parsing will work.
Example:
DateTime d = DateTime.ParseExact("01.07.2014", "dd/MM/yyyy", CultureInfo.GetCultureInfo("de"));
You can also use a literal period instead of the date separator specificer, then it works with the invariant culture:
DateTime d = DateTime.ParseExact("01.07.2014", "dd.MM.yyyy", CultureInfo.InvariantCulture);
Ref: Custom Date and Time Format Strings
The format you have is different from the string provided:
Try either of the below, it will work :)
DateTime d1 = DateTime.ParseExact("01/07/2014", "dd/MM/yyyy", CultureInfo.InvariantCulture);
DateTime d2 = DateTime.ParseExact("01.07.2014", "dd.MM.yyyy", CultureInfo.InvariantCulture);
Problem:
Your separator in date is . while in string format it is /
Solution:
Your format should be "dd.MM.yyyy" or "MM.dd.yyyy" as your date is "01.07.2014". 01 and 07 exist both as date and month.
This date can be 01st July 2014 or 07 Jan 2014.
Your code should be
DateTime d = DateTime.ParseExact("01.07.2014",
"dd.MM.yyyy",
CultureInfo.InvariantCulture);
OR
DateTime d = DateTime.ParseExact("01.07.2014",
"MM.dd.yyyy",
CultureInfo.InvariantCulture);
I'm trying to convert string which comes from textbox, for example in this format '03/24/2014' to DateTime. This is what I'm trying:
CultureInfo us = new CultureInfo("en-US");
dtAssemblyDate = DateTime.ParseExact(txtOperationSignatureDate.Value, "dd/MM/yyyy", us);
or
dtAssemblyDate = DateTime.ParseExact(txtOperationSignatureDate.Value, "dd/MM/yyyy", null);
But no luck and I'm getting exceptions that the value cannot be casted as DateTime. How can I fix this problem?
03/24/2014 isn't a valid date in dd/MM/yyyy format (there are only 12 months in a year1).
Either change your format string to MM/dd/yyyy or use a valid date in your chosen format.
1: Or 13 months in some types of Calendar, but "en-US" uses the 12-month Gregorian calendar.
DateTime myDate = DateTime.ParseExact("24/03/2014", "dd/MM/yyyy",
System.Globalization.CultureInfo.InvariantCulture);
03/24/2014 has the day of the month as the middle component. That might seem strange, but that's how it's done in some parts of the world (mostly Northern America).
Thus, when specifying the format for parsing, you also have to put the day of the month (dd) in the middle:
CultureInfo us = new CultureInfo("en-US");
dtAssemblyDate = DateTime.ParseExact(txtOperationSignatureDate.Value, "MM/dd/yyyy", us);
Obviously, it is not possible to parse a text field that accepts both middle-endian (MM/dd/yyyy) and small-endian (dd/MM/yyyy) dates, because ambiguities like 01/02/2014 cannot be resolved automatically.
If the string is expressed in the format MM/dd/yyyy then
CultureInfo us = new CultureInfo("en-US");
dtAssemblyDate = DateTime.ParseExact(txtOperationSignatureDate.Value, "MM/dd/yyyy", us);
but I prefer to use DateTime.TryParse to avoid surprises...
if(DateTime.TryParse(txtOperationSignatureDate.Value,
CultureInfo.InvariantCulture,
DateTimeStyles.None,
out dtAssemblyDate))
Console.WriteLine(dtAssemblyDate.ToShortDateString());
CultureInfo us = new CultureInfo("en-US");
DateTime dt = Convert.ToDateTime(txtOperationSignatureDate.Value, us.DateTimeFormat);
Whatever DateTimeFormat you require, you just need to pass corresponding culture with it.
Try using
string date = textbox.Value;
DateTime dt = Convert.ToDateTime(date);
I want to format the input string into MM/dd/yyyy hh:mm:ss format in C#.
The input string is in format MM/dd/yyyy hh:mm:ss
For example :"04/30/2013 23:00"
I tried Convert.ToDateTime() function, but it considers 4 as date and 3 as month which is not what I want. Actually month is 04 and date is 03.
I tried DateTime.ParseExact() function also, But getting Exception.
I am getting error:
String was not recognized as a valid DateTime.
Your date time string doesn't contains any seconds. You need to reflect that in your format (remove the :ss).
Also, you need to specify H instead of h if you are using 24 hour times:
DateTime.ParseExact("04/30/2013 23:00", "MM/dd/yyyy HH:mm", CultureInfo.InvariantCulture)
See here for more information:
Custom Date and Time Format Strings
You can use DateTime.ParseExact() method.
Converts the specified string representation of a date and time to its
DateTime equivalent using the specified format and culture-specific
format information. The format of the string representation must match
the specified format exactly.
DateTime date = DateTime.ParseExact("04/30/2013 23:00",
"MM/dd/yyyy HH:mm",
CultureInfo.InvariantCulture);
Here is a DEMO.
hh is for 12-hour clock from 01 to 12, HH is for 24-hour clock from 00 to 23.
For more information, check Custom Date and Time Format Strings
try this:
string strTime = "04/30/2013 23:00";
DateTime dtTime;
if(DateTime.TryParseExact(strTime, "MM/dd/yyyy HH:mm",
System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.None, out dtTime))
{
Console.WriteLine(dtTime);
}
This can also be the problem if your string is 6/15/2019. DateTime Parse expects it to be 06/15/2019.
So first split it by slash
var dateParts = "6/15/2019"
var month = dateParts[0].PadLeft(2, '0');
var day = dateParts[1].PadLeft(2, '0');
var year = dateParts[2]
var properFormat = month + "/" +day +"/" + year;
Now you can use DateTime.Parse(properFormat, "MM/dd/yyyy"). It is very strange but this is only thing working for me.
change the culture and try out like this might work for you
string[] formats= { "MM/dd/yyyy HH:mm" }
var dateTime = DateTime.ParseExact("04/30/2013 23:00",
formats, new CultureInfo("en-US"), DateTimeStyles.None);
Check for details : DateTime.ParseExact Method (String, String[], IFormatProvider, DateTimeStyles)
DateTime dt1 = DateTime.ParseExact([YourDate], "dd-MM-yyyy HH:mm:ss",
CultureInfo.InvariantCulture);
Note the use of HH (24-hour clock) rather than hh (12-hour clock), and the use of InvariantCulture because some cultures use separators other than slash.
For example, if the culture is de-DE, the format "dd/MM/yyyy" would expect period as a separator (31.01.2011).
Below code worked for me:
string _stDate = Convert.ToDateTime(DateTime.Today.AddMonths(-12)).ToString("MM/dd/yyyy");
String format ="MM/dd/yyyy";
IFormatProvider culture = new System.Globalization.CultureInfo("fr-FR", true);
DateTime _Startdate = DateTime.ParseExact(_stDate, format, culture);
You may use this type format (get formatted data from sql server)
FORMAT(convert(datetime,'16/04/2018 10:52:20',103),'dd/MM/yyyy HH:mm:ss', 'en-us')
CONVERT(VARCHAR,convert(datetime,'16/04/2018 10:52:20',103), 120)
