I am getting an error when I run the following line of code:
DateTime dt = DateTime.ParseExact(bolShipdate, "dd/MMM/yyyy", null);
The error is:
String was not recognized as a valid DateTime.
The bolShipdate value is 02-21-2016. I need to convert the date to 21-Feb-16.
How can I resolve this?
Your format in ParseExact needs to match your string. dd/MMM/yyyy doesn't match the sample data provided. try:
var bolShipdate = "02-21-2016";
DateTime dt = DateTime.ParseExact(bolShipdate, "MM-dd-yyyy", null);
Console.WriteLine(dt.ToString("dd-MMM-yy")); // Dispays 21-Feb-16
(Example fiddle)
Declaration of DateTime.ParseExact is
public static DateTime ParseExact(
string s,
string format,
IFormatProvider provider
)
Here you will want to pass the format you are parsing not the expected result. And it looks like your string is of the format MM-dd-yyyy.
You can then use .ToString(string format to get the date in your desired format:
string date = "02-21-2016";
DateTime dt = DateTime.ParseExact(date, "MM-dd-yyyy", CultureInfo.InvariantCulture);
string newFormat = dt.ToString("dd-MMM-yy");
Console.WriteLine(newFormat);
Hope this can resolve:
var date = "02-21-2016";
DateTime dt = DateTime.ParseExact(date, "MM-dd-yyyy", CultureInfo.InvariantCulture);
string result = dt.ToString("dd-MMM-yy");

I have a string ("CompletionDate") which contains the value "2/28/2017 5:24:00 PM"
Now I have 2 variables (EDate and ETime). I want to assign the Date to EDate (i.e 2/28/2017) and Time to ETime (i.e. 5:24:00 PM).
How can I split the Date and Time from a single string.
Kindly Help.
My approach right now is like :
string CompletionDate = string.Empty;
string ProjectEDate = string.Empty;
string ProjectETime = string.Empty;
CompletionDate = "2017-03-29 12:58:00";
DateTime dt = DateTime.ParseExact(CompletionDate, "yyyy-MM-dd", CultureInfo.CreateSpecificCulture("en-us"));
DateTime dt1 = DateTime.ParseExact(CompletionDate, "HH:mm:ss", CultureInfo.CreateSpecificCulture("en-us"));
var ProjectEDate = dt.ToString();
var ProjectETime = dt1.ToString();
But its throwing exception that string is not in correct format. Kindly help
#Chris pointed one of your problems, but you have one more. You are passing full date time string and trying to treat it as date or time only, which is not true. Instead I suggest you to parse DateTime object with both date and time, and then take whatever you need from parsed object:
CultureInfo enUS = CultureInfo.CreateSpecificCulture("en-us");
DateTime dt = DateTime.ParseExact(CompletionDate, "yyyy-MM-dd HH:mm:ss", enUS);
var ProjectEDate = dt.Date.ToString();
var ProjectETime = dt.TimeOfDay.ToString();
You need to specify the full format as same as the input string to parse method.
DateTime dt = DateTime.ParseExact(CompletionDate, "yyyy-MM-dd HH:mm:ss", System.Globalization.CultureInfo.CreateSpecificCulture("en-us"));
To get results you can use below methods available by default in DateTime.
dt.ToShortTimeString()
"12:58 PM"
dt.ToLongTimeString()
"12:58:00 PM"
dt.ToLongDateString()
"Wednesday, March 29, 2017"
dt.ToShortDateString()
"3/29/2017"
Or you can specify the format to ToString method.
dt.ToString("yyyy-MM-dd")
"2017-03-29"
dt.ToString("HH:mm:ss")
"12:58:00"
DateTime.ParseExact(CompletionDate, "yyy-MM-dd", ...
You are missing 4th 'y' in date format string:
"yyyy-MM-dd"
^
here
and:
String was not recognized as a valid DateTime " format dd/MM/yyyy"
Why do you parse into DateTime and then convert to a string using ToString again? Couldn´t you just simply use String.Split when all you want is to split the time from the day and you know the exact format?
var CompletionDate = "2017-03-29 12:58:00";
var tmp = CompletionDate.Split(' ');
var ProjectEDate = tmp[0];
var ProjectETime = tmp[1];
I tried the following but couldn't get it
string s= "2015-FEB-17";
//I want it to be converted to date format as
date = "20150217"
//I tried doing as follows but didn't work
var myDate = DateTime.ParseExact(dt, "yyyy-MMM-dd", CultureInfo.InvariantCulture);
why not shorten it since you are using the .ToString("yyyyMMdd") you are dropping the time portion of the new value
string sDateStr = "2015-FEB-17";
var newDateFrmt = Convert.ToDateTime(sDateStr).ToString("yyyyMMdd");
20150217 becomes the expected answer based on the format..
not to be redundant this approach can also be taken
string sDateStr = "2015-FEB-17";
var someDate = DateTime.ParseExact(sDateStr, "yyyy-MMM-dd", CultureInfo.InvariantCulture);
var newDateFrmt = someDate.ToString("yyyyMMdd");
ParseExact turns the string into a DateTime. You then need to format the DateTime as a string.
string s= "2015-FEB-17";
DateTime myDate = DateTime.ParseExact(s, "yyyy-MMM-dd", CultureInfo.InvariantCulture);
string result = myDate.ToString("yyyyMMdd"); // now it's "20150217"
Also, you were missing dashes in the ParseExact format string.
If your application only handles US-style dates with no internationalization, it's best to specify CultureInfo.InvariantCulture.
Try
var myDate = DateTime.ParseExact(s, "yyyy-MMM-dd", CultureInfo.InvariantCulture);
var q = myDate.ToString("yyyyMMdd");
or just
var q = DateTime.ParseExact(s, "yyyy-MMM-dd", CultureInfo.InvariantCulture)
.ToString("yyyyMMdd");
I am getting a string in the following format
string dt= "\"2014-06-01T05:00:00.000Z\""
I am trying to convert it to Date following way
mDateTime dt = Convert.ToDateTime(dt)
I get error saying When converting string to date time use parse the string.
Please let me know how I can parse the string to date. Thanks
Convert.ToDateTime method fails because this is not a standard date and time pattern for your CurrentCulture (And probably no culture support this format).
You can use custom date and time formatting with DateTime.TryParseExact or DateTime.ParseExact methods.
Here an example on LINQPad;
string s = "\"2014-06-01T05:00:00.000Z\"";
DateTime dt;
if(DateTime.TryParseExact(s, "'\"'yyyy-MM-dd'T'HH:mm:ss.fff'Z\"'",
CultureInfo.InvariantCulture,
DateTimeStyles.None, out dt))
{
dt.Dump();
}
Output will be;
6/1/2014 5:00:00 AM
Here a demonstration.
At first you have to trim quotes, then parse:
DateTime result = DateTime.Parse(dt.Trim('\"'));
you can use below menioned code
string dt = "\"2014-06-01T05:00:00.000Z\"";
dt = dt.Replace("\"", "");
DateTime dt12 = Convert.ToDateTime(dt);
Try This:
string dt = "\"2014-06-01T05:00:00.000Z\"";
dt = dt.Replace("\"", "");
DateTime dtFinal = DateTime.ParseExact(dt,"yyyy-MM-ddTHH:mm:ss.fffZ",
CultureInfo.InvariantCulture);
Here I want to convert date into string using tostring but when I convert it back, (string to datetime), the format is different.
static void Main(string[] args)
{
string cc = "2014/12/2";
DateTime dt = DateTime.Parse(cc);
Console.WriteLine(dt);
Console.ReadLine();
}
expected output:
2014/12/2
But I get:
12/2/2014
string DateString = "06/20/1990";
IFormatProvider culture = new CultureInfo("en-US", true);
DateTime dateVal = DateTime.ParseExact(DateString, "yyyy-MM-dd", culture);
This will be your desire output
udpated
string DateString = "20/06/1990";;
IFormatProvider culture = new CultureInfo("en-US", true);
DateTime dt = DateTime.ParseExact(DateString,"dd/mm/yyyy",culture);
dt.ToString("yyyy-MM-dd");
Call ToString with format provided when you convert DateTime instance back to string:
Console.WriteLine(dt.ToString(#"yyyy/M/d");
try this
DateTime dt = DateTime.ParseExact(dateString, "ddMMyyyy",
CultureInfo.InvariantCulture);
dt.ToString("yyyyMMdd");
use this:
string cc = "2014/12/2";
DateTime dt = DateTime.Parse(cc);
string str = dt.ToString("yyyy/M/dd"); // 2014/12/02 as you wanted
Console.WriteLine(str);
Console.ReadLine();
As you can read here, DateTime.ToString() uses CurrentCulture to decide how to format its output (CurrentCulture of type CultureInfo provides information on how to format dates, currency, calendar etc. It is called locale in C++).
Thus, the simlplest solution as suggested by previous answers, is to use an overload of ToString() which accepts a format string, effectively overriding the CurrentCulture info:
dt.ToString(#"yyyy/MM/dd");
More on datetime formatting can be found here.
you can use
string formattedDate= dt.ToString("yyyy/M/d");
For reverse you can use
DateTime newDate = DateTime.ParseExact("2014/05/22", "yyyy/M/d", null);
So if your expected output is like : 2014/12/2
you have to use
newDate.ToString("yyyy/M/d");
This is simple, You just need to use date pattern during display
string cc = "2014/12/2";
string datePatt = #"yyyy/MM/d";
DateTime dt = Convert.ToDateTime(cc);
Console.WriteLine(dt.ToString(datePatt));
I need to use
SqlDateTime.Parse(val)
where val is a string such as " 23.3.1992 00:00:00 ".
The string is in European format, that is, day precedes month. However Parse wants "American" format. How I can tell it to use particular datetime format / locale?
Thanks in advance!
Try this:
string val = "23.12.1992 00:00:00";
// Parse exactly from your input string to the native date format.
DateTime dt = DateTime.ParseExact(val, "dd.M.yyyy hh:mm:ss", null);
// Part to SqlDateTime then
System.Data.SqlTypes.SqlDateTime dtSql = System.Data.SqlTypes.SqlDateTime.Parse(dt.ToString("yyyy/MM/dd"));
This could be done in one statement, but just separated for illustration.
Have you tried DateTime instead of SQLDateTime
DateTime d = DateTime.Parse(val);
String s = d.ToString(CultureInfo.CreateSpecificCulture("en-US"));
Can you try this ?
string valInEuropean = "23.3.1992 00:00:00";
DateTime dateInEuropean = DateTime.Parse(valInEuropean);
string valInAmerican = dateInEuropean.ToString("yyyy-MM-dd HH:mm:ww");
For converting a string to datetime object when the format is known(in this case )
use
DateTime dwweek = DateTime.ParseExact("23.3.1992 00:00:00", "dd.MM.yyyy hh:mm:ss", System.Globalization.CultureInfo.InvariantCulture);
