I am trying to convert this e.g. 12/31/2012 format into DateTime, however when I run this code the conversion works but the time is not current. I am looking to convert to DateTime but with the current time:
Example: When I run the below code and enter date: 12/31/2012
I get: 12/31/2012 12:00:00 AM
I am not sure how to get the current time instead of 12:00:00 AM
Console.Write("Enter Current Date: ");
string strMyDate = Console.ReadLine();
DateTime dt = DateTime.Parse(strMyDate);
Console.WriteLine(dt);
Console.ReadKey();
You can extract only the time from DateTime.Now by using the TimeOfDay property and add it to your manually entered date, e.g.
var time = dt.Add(DateTime.Now.TimeOfDay);
As an additional note, I would use DateTime.TryParse instead, as the value entered by the user may not be a parseable date, e.g.
DateTime dt;
var isDate = DateTime.TryParse(strMyDate, out dt);
if(isDate)
{
var time = dt.Add(DateTime.Now.TimeOfDay);
}
DateTime.Now will give you current time. Than combine date portion from first value with time portion from Now to get the result.
Add this to your string:
string strMyDate = Console.ReadLine();
strMyDate = string.Format("{0} {1}",
strMyDate,
DateTime.Now.ToShortTimeString());
Haven't actually compiled this but something like this should work:
DateTime dt = DateTime.Parse("12/31/2012 " + DatTime.Now.TimeOfDay.ToString());
You can build up the time from the hours, minutes and seconds portion of DateTime.Now;
string strMyDate = "12/31/2012";
DateTime dt = DateTime.Parse(strMyDate);
DateTime current = DateTime.Now;
dt = dt.AddHours(current.Hour).AddMinutes(current.Minute).AddSeconds(current.Second);
Console.WriteLine(dt);

I have a DataGrid which contains a few values that are in hours and I wanted to know:
How to get ONLY the time from my DataGrid and convert it into an int (or double) variable.
My goal is to do a few operations with my DataGrid time values, like to add numbers into it
EXAMPLE:
Using my "dataGridView1.Rows[1].Cells[2].Value.ToString();" It'll show a DateTime value (which is inside my DataGrid), with this value, I wanna filter ONLY the time from this and convert it into an int
the part of my code which I wanna "capture" the time:
txtAtiv.Text = dataGridView1.Rows[0].Cells[1].Value.ToString();
string value = dataGridView1.Rows[0].Cells[2].Value.ToString();
lblLeft.Text = value.Split(' ')[1];
I wanna get the "value" (which is a DateTime value from the DataGrid) and convert it into an int.
note:
- The date for me in my dataGrid it's not relevant, I only have to pick the time (and yes, I know that I can't "split" DateTime to do them separately)
If you are willing to be limited to millisecond resolution, then this is fairly easy.
Given a date/time that you want to get the time part from as an int, you can get the number of milliseconds since midnight, like so:
DateTime dateTime = DateTime.Now;
int timeMsSinceMidnight = (int)dateTime.TimeOfDay.TotalMilliseconds;
If you want to reconstitute the original date and time from this, you need the original date and the time since midnight in milliseconds:
DateTime date = dateTime.Date; // Midnight.
DateTime restoredTime = date.AddMilliseconds(timeMsSinceMidnight);
Test program:
DateTime dateTime = DateTime.Now;
Console.WriteLine("Original date/time: " + dateTime );
int timeMsSinceMidnight = (int)dateTime.TimeOfDay.TotalMilliseconds;
DateTime date = dateTime.Date; // Midnight.
DateTime restoredTime = date.AddMilliseconds(timeMsSinceMidnight);
Console.WriteLine("Restored date/time: " + restoredTime);
The value returned from time.TimeOfDay is of type TimeSpan, which is convenient for storing time-of-day values.
If you want to turn your "milliseconds since midnight" back into a TimeSpan, you just do this:
var timeSpan = TimeSpan.FromMilliseconds(timeMsSinceMidnight);
First step is to convert string to DateTime. Use DateTime.TryParse(string value, out DateTime dt). Then as Mathew Watson rightly suggested, get the value of variable dt converted to milliseconds using dt.TimeOfDay.TotalMilliseconds. It is also possible to convert the span in TotalSeconds or TotalMinutes if it suits your requirement.
Try to avoid calling ToString() method directly before checking if cell value is null. If I want to avoid the check, I would make compiler to do it by using something like : Rows[3].Cells[2].Value + "" instead of Value.ToString().
Mixing Mathew's and Mukesh Adhvaryu's answers, I got into this one, and it fits perfectly on what I need, thank you guys for your support!
txtAtiv.Text = dataGridView1.Rows[0].Cells[1].Value + "";
string value = dataGridView1.Rows[0].Cells[2].Value + "";
lblLeft.Text = value.Split(' ')[1];
textStatus.Text = "";
DateTime timeConvert;
DateTime.TryParse(value, out timeConvert);
double time;
time = timeConvert.TimeOfDay.TotalMilliseconds;
var timeSpan = TimeSpan.FromMilliseconds(time);
lblSoma.Text = timeSpan.ToString();
static void Main(string[] args)
{
string time1 = "11:15 AM";
string time2 = "11:15 PM";
var t1 = ConvertTimeToInt(time1);
var t2 = ConvertTimeToInt(time2);
Console.WriteLine("{0}", t1);
Console.WriteLine("{0}", t2);
Console.WriteLine("{0:dd/MM/yyyy hh:mm tt}", ConvertIntToTime(t1));
Console.WriteLine("{0:dd/MM/yyyy hh:mm tt}", ConvertIntToTime(t2));
Console.ReadLine();
}
static long ConvertTimeToInt(string input)
{
var date = DateTime.ParseExact(input, "hh:mm tt", CultureInfo.InvariantCulture);
TimeSpan span = date.TimeOfDay;
Console.WriteLine("{0:dd/MM/yyyy hh:mm tt}", date);
return span.Ticks;
}
static DateTime ConvertIntToTime(long input)
{
TimeSpan span = TimeSpan.FromTicks(input);
var date = new DateTime(span.Ticks);
Console.WriteLine("{0:dd/MM/yyyy hh:mm tt}", date);
return date;
}
How can I get a DateTime based on a string
e.g:
if I have mytime = "14:00"
How can I get a DateTime object with current date as the date, unless current time already 14:00:01, then the date should be the next day.
This is as simple as parsing a DateTime with an exact format.
Achievable with
var dateStr = "14:00";
var dateTime = DateTime.ParseExact(dateStr, "H:mm", null, System.Globalization.DateTimeStyles.None);
The DateTime.ParseExact() (msdn link) method simply allows you to pass the format string you wish as your parse string to return the DateTime struct. Now the Date porition of this string will be defaulted to todays date when no date part is provided.
To answer the second part
How can I get a DateTime object with current date as the date, unless
current time already 14:00:01, then the date should be the next day.
This is also simple, as we know that the DateTime.ParseExact will return todays date (as we havevnt supplied a date part) we can compare our Parsed date to DateTime.Now. If DateTime.Now is greater than our parsed date we add 1 day to our parsed date.
var dateStr = "14:00";
var now = DateTime.Now;
var dateTime = DateTime.ParseExact(dateStr, "H:mm", null, System.Globalization.DateTimeStyles.None);
if (now > dateTime)
dateTime = dateTime.AddDays(1);
You can use DateTime.TryParse(): which will convert the specified string representation of a date and time to its DateTime equivalent and returns a value that indicates whether the conversion succeeded.
string inTime="14:00";
if(DateTime.TryParse(inTime,out DateTime dTime))
{
Console.WriteLine($"DateTime : {dTime.ToString("dd-MM-yyyy HH:mm:SS")}");
}
Working example here
There is a datetime constructor for
public DateTime(
int year,
int month,
int day,
int hour,
int minute,
int second
)
So then parse the string to find the hours, minutes, and seconds and feed that into this constructor with the other parameters supplied by Datetime.Now.Day and so on.
I think you want to do something like this:
string myTime = "14:00";
var v = myTime.Split(":".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);
DateTime obj = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, int.Parse(v[0]), int.Parse(v[1]), DateTime.Now.Second);
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 want to split this 2015-08-11 10:59:41.830 value which is in datetime datatype format and convert it to the following format using c# asp.net.
August 11, 45 minutes ago
The given datetime(i.e-2015-08-11 10:59:41.830) will compare with the current datetime and display like the above format.Please help me to do this.
You will need to parse your date using DateTime.Parse(string s) and once you have that, you take the current date (DateTime.Now) and subtract from it the parsed date.
This should yield a TimeSpan struct. Assuming that both of the dates will refer to the same date, you can then construct your string by taking the pieces you need from the parsed date (Day and Month) and from the time span (Hours, minutes and seconds).
For your specific format you can try ParseExact() "yyyy-MM-dd HH:mm:ss.fff"
static void Main(string[] args)
{
//Given that previous and and now is the same day
DateTime previous = DateTime.ParseExact("2015-08-18 10:59:41.830", "yyyy-MM-dd HH:mm:ss.fff",
System.Globalization.CultureInfo.InvariantCulture);
DateTime now = DateTime.Now;
double value = now.Subtract(previous).TotalMinutes;
Console.WriteLine(string.Format("{0:MMMM dd}, {1} minutes ago", now, (int)value));
Console.ReadLine();
}
npinti already explained it, here the code part;
string s = "2015-08-18 10:59:41.830";
DateTime dt;
if(DateTime.TryParseExact(s, "yyyy-MM-dd HH:mm:ss.fff", CultureInfo.InvariantCulture,
DateTimeStyles.None, out dt))
{
var ts = dt - DateTime.Now;
Console.WriteLine("{0}, {1} minutes ago",
dt.ToString("MMMM dd", CultureInfo.InvariantCulture),
ts.Minutes);
}
I run this code 2015-08-18 09:50 in my local time and it's generate August 18, 9 minutes ago as a result.
Remember, Minutes property represents minute component of the TimeSpan object and it's range is from -59 to 59. If you wanna get all minutes based on TimeSpan object value, you can use TotalMinutes property (or even as (int)ts.TotalMinutes).
You need this
var yourString = "2015-08-11 10:59:41.830";
var oldDate = DateTime.ParseExact(yourString, "yyyy-MM-dd hh:mm:ss.fff", CultureInfo.InvariantCulture);
//The above two steps are only for if you have date in `string` type, but if you have date in `DateTime` format then skip these.
var difference = DateTime.Now - oldDate;
//here old date is parsed from string or your date in `DateTime` format
var result = string.Format("{0:MMMM dd}, {1} minutes ago", oldDate, difference.Minutes);
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);
