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);

I read date-time strings from a file in 2 different formats:
19/02/2019 08:24:59
2/17/2019 12:25:46 PM
For the first format the custom format string I wrote is:
string firstDate = "19/02/2019 08:24:59";
string customFormatForFirstDateTimeString = "dd/mm/yyyy hh:mm:ss";
and I use it as follows:
string firstResultingDateAndTime;
bool parsingSuccessful = DateTime.TryParseExact(
firstDate,
customFormatForFirstDateTimeString,
System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.None,
out firstResultingDateAndTime);
The problem is that parsingSuccessful results false.
For the second date-time string, the code is as follows:
string secondDate = "2/17/2019 12:25:46 PM";
string customFormatForSecondDateTimeString = "m/dd/yyy hh:mm:ss PM";
string secondResultingDateAndTime;
parsingSuccessful = DateTime.TryParseExact(
secondDate,
customFormatForSecondDateTimeString,
System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.None,
out secondResultingDateAndTime);
Also here I receive
parsingSuccessful == false;
I reckon that the custom format strings do not fit the date-time strings, but I was not able to figure out why.
Please help.
Thank you in advance.
Well, mm stands for minutes, not months (we have MM for it) that's why dd/mm/yyyy format should be dd/MM/yyyy.
Another issue with hour format where we have hh for 0..12 range (with tt for AM/PM) and HH for 0..23 interval:
string firstDate = "19/02/2019 08:24:59";
// Since we don't have AM / PM we can conclude that hour is in 0..23 range
string customFormatForFirstDateTimeString = "dd/MM/yyyy HH:mm:ss";
string secondDate = "2/17/2019 12:25:46 PM";
string customFormatForSecondDateTimeString = "M/dd/yyyy hh:mm:ss tt";
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"));

string final = Convert.ToString(DateTime.Parse(date, System.Globalization.CultureInfo.InvariantCulture) + TimeSpan.Parse(duration));
Hi, I use the above code to add two date's to eachother. It do work very well on Windows and returns the required format yyyy-MM-dd HH:mm:ss in a correct fashion. HOWEVER, when on Linux building with Mono it returns the following format dd/MM/yyyy HH:mm:ss which is not what I want.
How can I specify that I ONLY want the first formatting and nothing else? I tried playing around with ParseExact but it did not do very well. What I've heard ParseExact should not really be needed for this?
Here is a example of input:
string date = "2014-10-30 10:00:04"; // On windows
string duration = "05:02:10"; // duration to be added to date
Greetings.
Use ToString("yyyy-MM-dd HH:mm:ss") instead of Convert.ToString.
string date = "2014-10-30 10:00:04";
string duration = "05:02:10";
DateTime dt1 = DateTime.Parse(date, CultureInfo.InvariantCulture);
TimeSpan ts = TimeSpan.Parse(duration, CultureInfo.InvariantCulture);
DateTime dtFinal = dt1.Add(ts);
string final = dtFinal.ToString("yyyy-MM-dd HH:mm:ss", CultureInfo.InvariantCulture);
Convert.ToString uses your current culture's date separator, use CultureInfo.InvariantCulture.
Read: Custom Date and Time Format Strings
You can use the ToString() Method of the DateTime object.
var dt = DateTime.Now;
dt.ToString("yyyy-MM-dd HH:mm");
Using your code:
string _final = (DateTime.Parse(date, System.Globalization.CultureInfo.InvariantCulture) + TimeSpan.Parse(duration)).ToString("yyyy-MM-dd HH:mm:ss");
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)
Given two strings
string date = "02Mar13";
string duration = "03.20min";
How do I parse them to DateTime and show them in the following format
string date = "02 March 2013";
string duration = "00:03:20";
I went through the list here but no one match my requirements.
You need to parse these using a Custom Date and Time format string, and output using one as well:
DateTime dt = DateTime.ParseExact(date + duration,
"ddMMMyymm.ss'min'",
CultureInfo.InvariantCulture);
string newDate = dt.ToString("dd MMMM yyyy");
string newDuration = dt.ToString("HH:mm:ss");
Things to note: I am using 'min' to represent the min literal in the string - this is part of custom format strings, allowing inner string literals.
string date = "02Mar13";
string duration = "03.20min";
DateTime newDate = DateTime.ParseExact(date + duration, "ddMMMyymm.ss\\min", null);
date = newDate.ToString("dd MMMM yyyy");
duration = newDate.ToString("hh:mm:ss");
How can produce the dateResult
string date = "02Mar13";
string duration = "03.20min";
var mat=Regex.Match(duration, "(.+?)min");
var dateResult = DateTime.ParseExact(date + mat.Groups[1].Value.Replace(".",":"), "ddMMMyyHH:mm", Thread.CurrentThread.CurrentCulture);
DateTime parsing is pretty much straightforward using DateTime.ParseExact:
DateTime.ParseExact(date, "ddMMMyy", null).ToString("dd MMMM yyyy"); // "02 March 2013"
As for the second part, if it is a duration semantically, then it is more suitable to use TimeSpan.ParseExact (although it required some fiddling with format strings):
TimeSpan.ParseExact(duration, "mm\\.ss'min'", null).ToString("hh\\:mm\\:ss"); // "00:03:20"
