I have this:
var dateString = string.Format("{0:dd/MM/yyyy}", date);
But dateString is 13.05.2011 instead of 13/05/2011. Can you help me?
You could use DateTime.ToString with CultureInfo.InvariantCulture instead:
var dateString = date.ToString("dd/MM/yyyy", CultureInfo.InvariantCulture);
The reason why / is replaced with . is that / is a custom format specifier
The "/" custom format specifier represents the date separator, which
is used to differentiate years, months, and days. The appropriate
localized date separator is retrieved from the
DateTimeFormatInfo.DateSeparator property of the
current or specified culture.
So either use InvariantCulture which uses / as date separator or - more appropriate - escape this format specifier by embedding it within ':
var dateString = date.ToString("dd'/'MM'/'yyyy");
Why this is more appropriate? Because you can still apply the local culture, f.e. if you want to output the month names, but you force / as date separator anyway.
// date separator in german culture is "." (so "/" changes to ".")
String.Format("{0:d/M/yyyy HH:mm:ss}", dt); // "9/3/2012 16:05:07" - english (en-US)
String.Format("{0:d/M/yyyy HH:mm:ss}", dt); // "9.3.2012 16:05:07" - german (de-DE)
so you have to change Culture from German to English!
you can write :
date.ToString(new CultureInfo("en-EN"));
try this:
var dateString = string.Format("{0:dd}/{0:MM}/{0:yyyy}", date);
Also check out Steve X's site for string formatting:
http://blog.stevex.net/string-formatting-in-csharp/
Simply try
var dateString = date.ToString("dd/MM/yyyy", new System.Globalization.CultureInfo("en-GB"));
If you want to force the date separator regardless of culture you can escape it, like this:
var dateString = string.Format(#"{0:dd\/MM\/yyyy}", date);
http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx
It seems a date seperator problem. Use this;
String.Format("{0:d/M/yyyy}", date);
Check String Format DateTime and look at DateTimeFormatInfo.DateSeperator property.
Try this:
var dateString = string.Format("{0:dd/MM/yyyy}", DateTime.Today, new System.Globalization.CultureInfo("en-GB"));

I know there is a lot of asked question here about DateTime but I saw them all already and seems not to find the right solution for my case.
Here is my code:
return DateTime.ParseExact(partialDate + dtfi.DateSeparator + _baseDate.ToString(), "dd/MM/yyyy", new CultureInfo("en-us");
This is throwing me an Exception.
Here is the value of the variables:
string partialDate = "1/22";
string dtfi.DateSeparator = "/";
int _baseDate = 2004;
You should use format "m/dd/yyyy" because datestring becomes 1/22/2004
return DateTime.ParseExact(partialDate + dtfi.DateSeparator + _baseDate.ToString(), "m/dd/yyyy", new CultureInfo("en-us"));
Unfortunately, both answers are wrong.
So, we all agree your result string will be "1/22/2004". Before looking which formats exactly matches your characters, let's look at your string is a standard date and time format for en-US culture or not.
DateTime.Parse("1/22/2004",
CultureInfo.GetCultureInfo("en-US")) // 22 January 2004 00:00:00
BANG!
We have a DateTime perfectly. But what if our string wouldn't be a standard date and time format for en-US culture? Then we can specify our format with DateTime.TryParseExact method. Let's look at which formats we can use to parsing our string.
1 matches with "M" custom format specifier which is from 1 to 12 and single-digit month is formatted without a leading zero.
/ is a DateSeparator and we can use it the same in our format because en-US culture has / as a DateSeparator already. Remember, "/" custom format specifier has a special meaning of replace me with current culture or supplied culture date separator
22 matches with "dd" custom format string which is from 01 to 31 and single-digit days is formatted with a leading zero. Remember, you can also use d format specifier in such a case but using wider formats is recommended.
2004 matches with "yyyy" custom format specifier which represents the year with a four digits.
So, the right format will be M/dd/yyyy in result.
string s = "1/22/2004";
DateTime dt;
if(DateTime.TryParseExact(s, "M/dd/yyyy", CultureInfo.GetCultureInfo("en-US"),
DateTimeStyles.None, out dt))
{
Console.WriteLine(dt); // 22 January 2004 00:00:00
}
You are referring to wrong format, so obviously it will throw exception. Below is what you are doing
string partialDate = "1/22";
string dtfi.DateSeparator = "/";
int _baseDate = 2004;
string ex = partialDate + dtfi.DateSeparator + _baseDate.ToString();
which gives you 1/22/2014 i.e., MM/dd/yyyy
and in code you are referring to
return DateTime.ParseExact(partialDate + dtfi.DateSeparator + _baseDate.ToString(), "dd/MM/yyyy", new CultureInfo("en-us");
Try using correct Format, to get the right result.
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"));

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 want to convert the date time to "MM/dd/yyyy" and when i am converting to this format the date is getting like "xx-xx-xxxx". I have written code like
var format = "MM/dd/yyyy HH:mm";
DateTime dt = DateTime.Now;
var dateString = dt.toString(format); // the value i am getting is 05-28-2014 12:47 but i require the 'dateString' value to be `05/28/2014 12:53`.
What is the issue with that.
Your currrent culture's date-separator seems to be - that's why you get it. You have to specify InvariantCulture:
string dateString = dt.toString("MM/dd/yyyy HH:mm", CultureInfo.InvariantCulture);
See: The "/" Custom Format Specifier
The "/" custom format specifier represents the date separator, which
is used to differentiate years, months, and days. The appropriate
localized date separator is retrieved from the
DateTimeFormatInfo.DateSeparator property of the current or specified
culture.
Another way is to escape the / with \:
string dateString = dt.toString(#"MM\/dd\/yyyy HH\:mm");
But in my opinion, if you already know the special meaning of / as "current culture's date-separator", it's better(in terms of readability) to use the correct CultureInfo (or InvariantCulture) instead.
This depends on your current culture date-separator. Try to include InvariantCulture as follows:
var dateStringFormat= dt.toString("MM/dd/yyyy HH:mm", CultureInfo.InvariantCulture);
Another way from #TimSchmelter's answer is to escape special symbols / and : so they are not treated as day and time separators.
var dateString = dt.toString(#"MM\/dd\/yyyy HH\:mm");
you will specified the format while converting date and time i.e. DateTime.Now.ToString("MM/dd/yyyy hh:mm ss tt")

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)
