The user is supposed to enter date in format: %m %d %Y
What I need to do is convert the date to: 11 11 2013 ( which is today`s date). I have not worked much with dates. Is there some method that does this conversion out of the box? I looked through DateTime options but couldn't find what I need.
Edit:
From the answers received it seems that it is not very clear what I am asking.
In our software the user can insert dates in format like this:
http://ellislab.com/expressionengine/user-guide/templates/date_variable_formatting.html
I am trying to parse this user input and return the today date. So from the link above:
%m - month - “01” to “12”
%d - day of the month, 2 digits with leading zeros - “01” to “31”
%Y - year, 4 digits - “1999”
I was wondering if there is a method that takes %m %d %Y as an input and returns the corresponding today date in the specified format ( which is 11 11 2013 today). Or at least something close to that.
Hope it is more clear now.
EDIT 2:
After digging a little bit more I found that what I am looking for is an equivalent of C++ strftime in C#.
http://www.cplusplus.com/reference/ctime/strftime/
But for some reason I cannot see an example this to implemented in C#.
You can use DateTime.TryParseExact to parse a string to date and DateTime-ToString to convert it back to string with your desired format:
DateTime parsedDate;
if (DateTime.TryParseExact("11 11 2013", "MM dd yyyy", System.Globalization.CultureInfo.InvariantCulture, System.Globalization.DateTimeStyles.None, out parsedDate))
{
// parsed successfully, parsedDate is initialized
string result = parsedDate.ToString("MM dd yyyy", System.Globalization.CultureInfo.InvariantCulture);
Console.Write(result);
}
My go-tos for DateTime Input and Output:
http://www.dotnetperls.com/datetime-parse for input (parsing)
http://www.csharp-examples.net/string-format-datetime/ for output (formatting)
string dateString = "01 01 1992";
string format = "MM dd yyyy";
DateTime dateTime = DateTime.ParseExact(dateString, format, CultureInfo.InvariantCulture);
Edit since his edit makes my above answer irrelevant (but will leave there for reference):
From what you're saying, you want to output today's date in a dynamically-defined format?
So if I want to see month, date, year, I say "MM dd YY" and you return it to me?
If so:
DateTime dt = DateTime.Today; // or initialize it as before, with the parsing (but just a regular DateTime dt = DateTime.Parse() or something quite similar)
Then
String formatString = "MM dd YY";
String.Format("{0:"+ formatString+"}", dt);
Your question is still quite unclear, though.
Use ParseExact:
var date = DateTime.ParseExact("9 1 2009", "M d yyyy", CultureInfo.InvariantCulture);

I have a list of DateTime as strings: dd.MM.yyyy H:mm:ss (The time is 24 hours format but the hour is single digit: 6 instead of 06)
14.12.2016 6:20:21
15.12.2016 8:30:00
16.12.2016 12:30:00
17.12.2016 14:33:00
18.12.2016 18:10:00
I am trying to parse exact the string values as a DateTime object like this:
DateTime.ParseExact(dt, "dd.MM.yyyy H:mm:ss", CultureInfo.InvariantCulture) (dt is the string value from the list)
The problem is I get an error saying the string is not a valid DateTime ...
With the current format, the first and second values in the list work fine, when it get's to the third 'boooom' I get the error.
Am I missing something in my format?
Use the overload of DateTime.ParseExact that accepts an array of valid formats:
string[] formats = { "dd.MM.yyyy H:mm:ss", "dd.MM.yyyy HH:mm:ss" };
var result = DateTime.ParseExact(dt, formats, CultureInfo.InvariantCulture, 0);
UPDATE: As others have noted, H should match both one-digit and two-digit hours, so something else is going on. The following code runs successfully on my system (.NET 4.5.2):
string dt = "16.12.2016 12:30:00";
var result = DateTime.ParseExact(dt, "dd.MM.yyyy H:mm:ss", CultureInfo.InvariantCulture);
I had to parse exact the using Hour, Minute, and Second then use the ToString method to convert to a Month, day, and year format
$myStringDate=[Datetime]::ParseExact($item.myDateObject,'MM/dd/yyyy H:mm:ss',$null).ToString('MM/dd/yyyy')
I am Trying to Convert Hijri Date into Gregorian Date I was following this article and My Code is as follows :
var cultureInfo = CultureInfo.CreateSpecificCulture("ar-sa");
string date = "19/12/36 12:00:00 ص";
Getting
string was not recognized as a valid datetime
error in below line
DateTime tempDate = DateTime.ParseExact(date, "dd/MM/yyyy", cultureInfo.DateTimeFormat, DateTimeStyles.AllowInnerWhite);
lblDate.Text = tempDate.ToString("dd/MM/yyyy");
I am getting string was not recognized as a valid datetime. Please can somebody tell me whats wrong with this code?
I think I'm on the right way but.. Let's try something at least.
First of all, DateTime values are always in the Gregorian calendar, basically. There's no such thing as "A DateTime in a UmAlQuraCalendar calendar" - which is used by ar-sa culture - you have to use the UmAlQuraCalendar to interpret a DateTime in a particular way.
Second, when you use DateTime.ParseExact for parsing your string, your string and format does match exactly based on culture you use. Since ص
character seems AMDesignator of ar-sa culture, you should provide tt specifier with your time part as well.
string s = "19/12/36 12:00:00 ص";
DateTime dt;
if(DateTime.TryParseExact(s, "dd/MM/yy hh:mm:ss tt", CultureInfo.GetCultureInfo("ar-sa"),
DateTimeStyles.None, out dt))
{
Console.WriteLine(dt);
}
Note: Since TwoDigitYearMax is 1451 of UmAlQuraCalendar calendar, your 36 will be parsed as 1436 with yy format specifier.
This perfectly parse your question but WAIT! What will be the result? Here it is.
02/10/2015 00:00:00
Why? As I said in the top, you have to use the UmAlQuraCalendar to interpret this DateTime instance.
UmAlQuraCalendar ul = new UmAlQuraCalendar();
Console.WriteLine(ul.GetYear(dt)); // 1436
Console.WriteLine(ul.GetMonth(dt)); // 12
Console.WriteLine(ul.GetDayOfMonth(dt)); // 19
i want to calculate a checktime to the time now and get the hours.
I have a string "time" for example...
Jun 06 2013 07:23:06
and with DateTime.Now I get the Time now. The Problem is now that i can't calculate the difference :(
I need them in my Project where I get from the License Server the time from a user and I want to show the difference to now. I want show this in hours.
You can use the Parse method of the DateTIme class to parse a string as a date and the subtract that from now.
TimeSpan diff = DateTime.Now - DateTime.Parse(dateString);
var hours = diff.Hours
The above exsmple of course requires the date to be in a specific format. You can if needed use DateTIme.ParseExact and specify a specific format yourself
You need to first convert your string to DateTime. here you have custom format so you can use DateTime.ParseExact or DateTime.TryParseExact method as below
DateTime dt;
if (DateTime.TryParseExact("Jun 06 2013 07:23:06", "MMM dd yyyy HH:mm:ss", CultureInfo.InvariantCulture,
DateTimeStyles.None, out dt))
{
// get difference
var inDays = (DateTime.Now - dt).Days;
}
You can use TimeSpan.Hours property like;
Gets the hours component of the time interval represented by the
current TimeSpan structure.
string dateString = "Jun 06 2013 07:23:06";
var differenceHours = (DateTime.Now - DateTime.Parse(dateString)).Hours;
Console.WriteLine(differenceHours);
Here a DEMO.
If you want to convert your custom formatted string to DateTime, you can use DateTime.ParseExact which need exact format matching between string and datetime.
Converts the specified string representation of a date and time to its
DateTime equivalent. The format of the string representation must
match a specified format exactly or an exception is thrown.
u may try it
DataTime diff = DateTime.Now - Convert.ToDataTime(dateString);
var hours = diff.Hours
I have a datetime column in database.
DateTime end_date = DateTime.ParseExact("2013-Jan-31", "yyyy-MM-dd", CultureInfo.InvariantCulture);
Why isn't this working?
This is not working because MM would mean January to be 01. If this is the format of the date you're trying to parse, try the format "yyyy-MMM-dd".
Hope this helps
Try like this;
DateTime a = DateTime.ParseExact("2013-Jan-31", "yyyy-MMM-dd", System.Globalization.CultureInfo.InvariantCulture);
Console.WriteLine (a);
Output:
31.01.2013
Look at from MSDN Custom Date and Time Format Strings
To use such a name of the month you need to take "MMM" so it will be
myObject.end_date = DateTime.ParseExact("2013-Jan-31", "yyyy-MMM-dd", System.Globalization.CultureInfo.InvariantCulture);
MM represents a two-digit numerical month (such as "01").
MMM represents the abbreviated month (such as "Jan").
Which means that you need
myObject.end_date = DateTime.ParseExact("2013-Jan-31", "yyyy-MMM-dd", System.Globalization.CultureInfo.InvariantCulture);
See http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx for a list of string format specifiers.
I have some date returned from FTP server like this
Aug 28 11:03
Aug 28 18:06
Sep 6 16:03
Im using this code to parse the time
CultureInfo provider = new CultureInfo("en-US");
_fileDateTime = DateTime.ParseExact(timestring, "MMM dd H:mm", provider);
The first two date work, but the last won't. Does any one have better ideas in parsing these kind of date format?
MMM d H:mm will work with Sep 6 16:03 but in my case its Sep 6 16:03 will not work, note the double space between Sep and 6
The first two date work, but the last won't.
That's because you are using dd for date and the last date returned is 6 and not 06. Use Single d. If last date returned was 06 your format would have worked like a charm.
Its should be like
DateTime.ParseExact(timestring, "MMM d H:mm", provider);
There are multiple issues, one is which is already pointed out in other answers i.e. using single d for date since last date is 6 not 06. The other problem with the last date is that it has multiple spaces in between date and month because of that your format which is taking care of dates with single space is not working. You need to first remove the extra space and then parse using format with single d. Try the following code:
string timestring = "Sep 6 16:03";
//string[] array = timestring.Split(" ".ToCharArray(),StringSplitOptions.RemoveEmptyEntries);
//timestring = string.Join(" ", array);
timestring = System.Text.RegularExpressions.Regex.Replace(timestring, #"\s+", " ");
CultureInfo provider = new CultureInfo("en-US");
DateTime _fileDateTime = DateTime.ParseExact(timestring, "MMM d H:mm", provider);
Use one d so it expects possible single-digit days (ie, "6" instead of "06").
MMM d H:mm
