I have string like this "24:00:00" and I would like to convert it to time. I tried convert and DateTime.Parse but it seems like it needs a date too. Is there a way to just get time, or do I have to put in a date as well?
If you are only interested in the time component, consider using TimeSpan instead of the full DateTime.
var time = TimeSpan.Parse("23:59:59");
I am not sure "24:00:00" is going to be a valid time. Any how, you should not need to specify the date, you can do...
DateTime time = DateTime.ParseExact("23:59:59", "HH:mm:ss", null);
If your time is actually a time of the day, then I would suggest sticking with DateTime. If you are actually using an amount of time (i.e. can be more that 23:59:59) then you could use TimeSpan...
TimeSpan time = TimeSpan.ParseExact("23:59:59", "HH:mm:ss", null);
don't forget, both have a TryParseExact version if you are not sure you input will be valid
You can use DateTimeFormatInfo to format your DateTime.
string strDate = "23:10:00";
DateTimeFormatInfo dtfi = new DateTimeFormatInfo();
dtfi.ShortTimePattern = "hh:mm:ss";
dtfi.TimeSeparator = ":";
DateTime objDate = Convert.ToDateTime(strDate, dtfi);
Console.WriteLine(objDate.TimeOfDay.ToString());
I think you need TimeSpan.Parse instead?
You can use timespan

How about
var time = new DateTime.Today;
var str = "24:00:00";
var split = str.split(":");
time.AddHours(Convert.ToInt32(split[0]));
time.AddMinutes(Convert.ToInt32(split[1]));
time.AddSeconds(Convert.ToInt32(split[2]));
Hope this helps.

I am new to C# and I have a string like "2021-06-14 19:27:14:979". Now I want to have only the time "19:27:14:979". So do I parse the string to a specific DateTime format and then convert it back to a string or would you parse or cut the string itself?
It is important that I keep the 24h format. I don't want AM or PM.
I haven't found any solution yet. I tried to convert it to DateTime like:
var Time1 = DateTime.ParseExact(time, "yyyy-MM-dd HH:mm:ss:fff");
var Time2 = Time1.ToString("hh:mm:ss:fff");
But then I lost the 24h format.
Your code is almost working, but ParseExact needs two additional arguments and ToString needs upper-case HH for 24h format:
var Time1 = DateTime.ParseExact("2021-06-14 19:27:14:979", "yyyy-MM-dd HH:mm:ss:fff", null, DateTimeStyles.None);
var Time2 = Time1.ToString("HH:mm:ss:fff");
Read: https://learn.microsoft.com/en-us/dotnet/standard/base-types/custom-date-and-time-format-strings#uppercase-hour-h-format-specifier
Instead of passing null as format provider(means current culture) you might want to pass a specifc CultureInfo, for example CultureInfo.CreateSpecificCulture("en-US").
You can just split it at the blank and take the last part like this
var timestamp = "2021-06-14 19:27:14:979";
var timePart = timestamp.Split(' ')[1];
in your case that seems easier than parsing into a DateTime and back into a string.
I have two parameters one for date and another for time, and i need date value part and time values part.
My two parameters are below.
// For Date parameter
DateTime dt = DateTime.ParseExact("01-jan-1999", "dd-MMM-yyyy", CultureInfo.InvariantCulture);
bo.Dateused5 = dt;
// For Time parameter
string Fromtiming = ddl_FromHours.SelectedItem.ToString() + ":" + ddl_FromMinutes.SelectedItem.ToString();
DateTime InterviewTime = Convert.ToDateTime(Fromtiming);//StartTime
bo.Dateused4 = InterviewTime;//InterviewTime
so i need to send mail to the candidate to only date part, should not contain time and time part, should not contain date.
are you looking for this:
DateTime dt = DateTime.ParseExact("01-jan-1999", "dd-MMM-yyyy", CultureInfo.InvariantCulture);
string mailDate = dt.ToString("dd-MMM-yyyy");// will give 01-jan-1999
string date = dt.ToString("dd-MM-yyyy"); // will give 01-01-1999
You can also try using String.Format()
string mailDate = String.Format("{0:dd-MM-yyyy}", dt); // will give 01-01-1999
You can use ToShortDateString():
DateTime dt = DateTime.ParseExact("01-jan-1999", "dd-MMM-yyyy", CultureInfo.InvariantCulture);
var date = dt.ToShortDateString();
Note that it uses date format attached to the current thread's culture info.
You would need to use strings rather than dates, so change the type of your variables to string so that
bo.Dateused5 = dt.ToString("dd-MMM-yyyy")
would set Dateused5 to a string of the date component, then
bo.Dateused4 = InterviewTime.ToString("HH:MM");
would set Dateused4 to the time component.
Couldn't test your code but I am very sure there are Functions "DateValue" and "TimeValue" you can make use of.
Something like,
Format(DateValue(any datetime), "dd-MM-yyyy")
gives you Only Date in the specified format. Similar way for TimeValue
I know there are allot of questions regarding this, but I've been trying all day to get this conversion to work and have had no luck when applying the answers to the same question posted here. Every time I try to Parse the string to a DateTime, I get a "String was not recognized as a valid DateTime" exception. If I use Convert.ToDateTime, I can get a Date back from my string, but I need the hh:ss as well.
Here is my simplified code that is ruining my day:
var test = "2015-05-08T05:00Z";
DateTime testTime = new DateTime();
//testTime = Convert.ToDateTime(test);
testTime = DateTime.ParseExact(test, "mm/DD/yyyy HH:ss",
System.Globalization.CultureInfo.InvariantCulture);
Console.WriteLine(testTime);
Why is this string not recognized as a valid DateTime when trying to convert?
All help is appreciated
Try this...
var test = "2015-05-08T05:00Z";
DateTime testTime = new DateTime();
testTime = DateTime.Parse(test, null, System.Globalization.DateTimeStyles.RoundtripKind);
Console.WriteLine(testTime);
Console.ReadLine();
Or even with DateTime.ParseExact()
var test = "2015-05-08T05:00Z";
DateTime testTime = new DateTime();
testTime = DateTime.ParseExact(test, "yyyy-MM-ddTHH:ssZ", System.Globalization.CultureInfo.InvariantCulture, DateTimeStyles.RoundtripKind);
Console.WriteLine(testTime);
Console.ReadLine();
Results:
The format string you are using ("mm/DD/yyyy HH:ss") doesn't match your input in any way.
Have you looked at the DateTime.ParseExact documentation? You could try something like this:
testTime = DateTime.ParseExact(test, "yyyy-MM-ddTHH:ssZ",
System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.AssumeUniversal);
A couple of notes:
There is no point in setting testTime = new DateTime() if you are going to parse it on the next line. Just drop that line entirely and use var testTime = DateTime.ParseExact(...);
Are you sure that HH:ss is what you want? That seems like a very strange way to write a time. HH:mm or mm:ss would make more sense.
You should fix your expected pattern and take the time zone into account.
If your need a DateTime of DateTimeKind.Local:
var date = DateTime.ParseExact("2015-05-08T05:00Z", "yyyy-MM-dd'T'HH:mm'Z'",
CultureInfo.InvariantCulture);
If your need a DateTime of DateTimeKind.Utc:
var date = DateTime.ParseExact("2015-05-08T05:00Z", "yyyy-MM-dd'T'HH:mm'Z'",
CultureInfo.InvariantCulture,
DateTimeStyles.AssumeUniversal
| DateTimeStyles.AdjustToUniversal);
You are doing an exact parse, which means that the parse format string must match exactly with your date literal string. But your parse format string in ParseExact
uses / instead of - in the test literal string.
has a space instead of the T in the test literal string
does not match Z at the end of your test literal string.
Further it is not in yyyy-MM-dd order of your test literal string.
#Shar1er80' s solution is nice and frees you from having to specify a correct parse format string for ParseExact. I'd recommend going with that.
However, if you want to use ParseExact, you need to do this:
testTime = DateTime.ParseExact(test, "yyyy-MM-ddTHH:ssZ",
System.Globalization.CultureInfo.InvariantCulture, System.Globalization.DateTimeStyles.AdjustToUniversal);
Note that I added a DateTimeStyle of AdjustToUniversal to ensure that your time is interpreted as UTC. The Z in the parse format string is just there to consume a Z. See https://stackoverflow.com/a/833143/49251 for more info on the issue of Z not actually being a part of the format string per se.
How can I convert a system date format (like 3/18/2014) to the format readable in DateTime?
I wanted to get the total days from two dates, which will come from two TextBoxes.
I have tried this syntax:
DateTime tempDateBorrowed = DateTime.Parse(txtDateBorrowed.Text);
DateTime tempReturnDate = DateTime.Parse(txtReturnDate.Text);
TimeSpan span = DateTime.Today - tempDateBorrowed;
rf.txtDaysBorrowed.Text = span.ToString();
But tempDateBorrowed always returns the minimum date for a DateTime varibale. I think this is because DateTime does not properly parse my system date format. As a consequence, it incorrectly displays the number of days. For example, if I try to enter 3/17/2014 and 3/18/2014 respectively, I always get -365241 days instead of 1.
Edit: I wanted my locale to be non-specific so I did not set a specific locale for my date format. (My system format by the way is en-US)
Try DateTime.ParseExact method instead.
See following sample code (I've used strings instead of TextBoxes since I used a Console app to write this code). Hope this helps.
class Program
{
static void Main(string[] args)
{
string txtDateBorrowed = "3/17/2014";
string txtReturnDate = "3/18/2014";
string txtDaysBorrowed = string.Empty;
DateTime tempDateBorrowed = DateTime.ParseExact(txtDateBorrowed, "M/d/yyyy", null);
DateTime tempReturnDate = DateTime.ParseExact(txtReturnDate, "M/d/yyyy", null);
TimeSpan span = DateTime.Today - tempDateBorrowed;
txtDaysBorrowed = span.ToString();
}
}
ToString is not Days
TimeSpan.TotalDays Property
You can try specifying the format of the datetime in the textboxes like this
DateTime tempDateBorrowed = DateTime.ParseExact(txtDateBorrowed.Text.Trim(), "M/d/yyyy", CultureInfo.InvariantCulture);
DateTime tempReturnDate = DateTime.ParseExact(txtReturnDate.Text.Trim(), "M/d/yyyy", CultureInfo.InvariantCulture);
Also you may have to check if the values from the textboxes are valid.
My first thought is to just replace the TextBox controls with a DateTimePicker or equivalent, depending on what platform you're developing on. Converting strings to dates or vice-versa is more of a pain than it seems at first.
Or you could try using DateTime.ParseExact instead, to specify the exact expected format:
DateTime tempDateBorrowed =
DateTime.ParseExact("3/17/2014", "M/dd/yyyy", CultureInfo.InvariantCulture);
Or you could specify a specific culture in the call to DateTime.Parse:
var tempDateBorrowed = DateTime.Parse("17/3/2014", new CultureInfo("en-gb"));
var tempDateBorrowed = DateTime.Parse("3/17/2014", new CultureInfo("en-us"));
try formatting your date to iso 8601 or something like that before parsing it with DateTime.Parse.
2014-03-17T00:00:00 should work with DateTime.Parse. ("yyyy-MM-ddTHH:mm:ssZ")
Try this:
if(DateTime.TryParseExact(txtDateBorrowed.Text, "M/d/yyyy", CultureInfo.InvariantCulture, DateTimeStyles.None, out tempDateBorrowed))
{
TimeSpan span = DateTime.Today - tempDateBorrowed;
}
I have a date that shows up as 10/18/2011 3:12:33 PM
How do I get only the time portion of this datetime?
I am using C#.
I tried:
string timeval = PgTime.ToShortTimeString();
but that did not work as Intellisense only showed ToString();
Assuming that
DateTime PgTime;
You can:
String timeOnly = PgTime.ToString("t");
Other format options can be viewed on MSDN.
Also, if you'd like to combine it in a larger string, you can do either:
// Instruct String.Format to parse it as time format using `{0:t}`
String.Format("The time is: {0:t}", PgTime);
// pass it an already-formatted string
String.Format("The time is: {0}", PgTime.ToString("t"));
If PgTime is a TimeSpan, you have a few other options:
TimeSpan PgTime;
String formattedTime = PgTime.ToString("c"); // 00:00:00 [TimeSpan.ToString()]
String formattedTime = PgTime.ToString("g"); // 0:00:00
String formattedTime = PgTime.ToString("G"); // 0:00:00:00.0000000
If you want a formatted string, just use .ToString(format), specifying only time portions. If you want the actual time, use .TimeOfDay, which will be a TimeSpan from midnight.
DateTime PgTime = new DateTime();
var hr = PgTime.Hour;
var min = PgTime.Minute;
var sec = PgTime.Second;
//or
DateTime.Now.ToString("HH:mm:ss tt") gives it to you as a string.
Don't now nothing about a class named PgTime. Do now about DateTime, though.
Try
DateTime instance = DateTime.Now ; // current date/time
string time = instance.ToString("t") ; // short time formatted according to the rules for the current culture/locale
Might want to read up on Standard Date and Time Format Strings and Custom Date and Time Format Strings
In C# 10 you can use TimeOnly.
TimeOnly date = TimeOnly.FromDateTime(PgTime);
