I have a string 2016. I am wondering how can I parse this string to a date time?
I have tried Datetime.ParseExact but it said it is not a valid format
string period = "2016"
DateTime date = DateTime.ParseExact(period, "YYYY", CultureInfo.InvariantCulture);
Help will be appreciated. Thanks
use "yyyy" instead for YYYY then you will get the expected answer;
string period = "2016";
DateTime date = DateTime.ParseExact(period, "yyyy", CultureInfo.InvariantCulture);

I'm trying to parse a date string in mm/dd/yyyy to date type, but it triggers an error saying:
String was not recognized as a valid DateTime.
This is the code I'm using:
Dim mydate As Date
If filter = 4 Then
mydate = Date.ParseExact(datepart, "mm/dd/yy", System.Globalization.DateTimeFormatInfo.InvariantInfo)
End If
I don't understand what I did wrong, any help is appreciated.
You have two little errors in your format string:
DateTime mydate = DateTime.ParseExact("07/27/2016",
"MM/dd/yyyy",
System.Globalization.DateTimeFormatInfo.InvariantInfo);
Months are parsed by "MM" not "mm" (lower case is for minutes)
The four digit year is parsed by "yyyy" not "yy"
Your date format is wrong, use MM/dd/yyyy instead mm/dd/yy try below
Date.ParseExact(datepart, "MM/dd/yyyy", CultureInfo.InvariantCulture)
CultureInfo provider = CultureInfo.InvariantCulture;
// Parse date-only value with invariant culture.
string dateString = "06/15/2008";
string format = "d";
var result = DateTime.ParseExact(dateString, format, provider);
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);
I have I have Excel file from where I am getting date in string format as "30-12-1899 07:50:00:AM"
When I am trying to convert it to DATETIME then it is giving error as
String was not recognized as a valid DateTime
I am trying to convert it like this
Convert.ToDateTime(homeToSchool[7],new DateTimeFormatInfo { ShortDatePattern = "dd-MM-yyyy", DateSeparator = "-" })
Use DateTime.ParseExact
string myDate = "30-12-1899 07:50:00:AM";
DateTime dt1 = DateTime.ParseExact(myDate, "dd-MM-yyyy hh:mm:ss:tt",
CultureInfo.InvariantCulture)

Since you are reading this from excel I hope this would help
DateTime.FromOADate(homeToSchool[7].ToString("dd-MMM-yyyy");
I have a string like this:
3/4/2013 or like this 11/10/2012. This is in mm/dd/yyyy format which I want to convert to MM/dd/yyy. I am doing like this:
DateTime publicationDate = DateTime.ParseExact(myDate, "MM/dd/yyyy", CultureInfo.InvariantCulture);
This is throwing me an error:
String was not recognized as a valid DateTime.
What is going on here?
EDIT:
After reviewing all the answers, I want to show Month and Day of the DateTime variable.
So I cannot do something like this:
string publicationDate = DateTime.ParseExact(myDate, "M/d/yyyy", CultureInfo.InvariantCulture).ToString("MM/dd/yyyy");
Having a string will not solve my problem because I am using this variable to show only day and month.
When I tried parsing this 'publicationDate' back to DateTime is truncates the '0's from month and day.
Hope I made my point here.
Answered:
string publicationDate = DateTime.ParseExact(myDate, "M/d/yyyy", CultureInfo.InvariantCulture).ToString("MM/dd");
You should add leading zeroes to the month and day.
This way: 04/03/2013
var myDateTime = DateTime.ParseExact(
"03/04/2013",
"MM/dd/yyyy",
System.Globalization.CultureInfo.InvariantCulture);
If leading zeroes are a problem, then do:
var myDateTime = DateTime.ParseExact(
"3/4/2013",
"M/d/yyyy",
System.Globalization.CultureInfo.InvariantCulture);
Finally, if you want to add leading zeroes:
string myFormattedDateTime = DateTime.ParseExact(
"3/4/2013",
"M/d/yyyy",
System.Globalization.CultureInfo.InvariantCulture)
.ToString("MM/dd/yyyy");
Use this pattern instead: "M/d/yyyy" to parse it and "MM/dd/yyyy" for ToString:
DateTime publicationDate = DateTime.ParseExact(dt, "M/d/yyyy", CultureInfo.InvariantCulture);
// if you want to display two digits for day and month:
Console.WriteLine(publicationDate.ToString("MM/dd/yyyy"));
It works for both as you can see here: http://ideone.com/M7luBD
Simple solution was this:
string publicationDate = DateTime.ParseExact(myDate, "M/d/yyyy", CultureInfo.InvariantCulture).ToString("MM/dd");
Thank you all for your answers!
Convert your string ToDateTime first. Make sure you have leading zeroes.
string date = "03/04/2013";
DateTime dt = Convert.ToDateTime(date);
[TestCase("3/4/2013", 3, 4, 2013)]
[TestCase("11/4/2013", 11, 4, 2013)]
public void DateTest(string date, int month, int day, int year)
{
var publicationDate = DateTime.ParseExact(date, "M/d/yyyy", CultureInfo.InvariantCulture);
Assert.AreEqual(day, publicationDate.Day);
Assert.AreEqual(month, publicationDate.Month);
Assert.AreEqual(year, publicationDate.Year);
}
Both test cases pass.
If your format asks for MM/dd/yyyy then you need to supply the string as such (04/03/2013 instead of 4/3/2013). So either
use M/d/yyyy if your supplied date is without leading zero's
or use the MM/dd/yyyy if you can supply leading zero's
My app parses a string data, extracts the date and identify the format of the date and convert it to yyyy-MM-dd.
The source date could be anything lime dd-mm-yyyy, dd/mm/yyyy, mm-dd-yyyy, mm/dd/yyyy or even yyyy-MM-dd.
Other than attempting different permutations and combinations using switch case, is there any other efficient way to do it?
string sourceDate = "31-08-2012";
String.Format("{0:yyyy-MM-dd}", sourceDate);
The above code simply returns the same sourceDate "31-08-2012".
string DateString = "11/12/2009";
IFormatProvider culture = new CultureInfo("en-US", true);
DateTime dateVal = DateTime.ParseExact(DateString, "yyyy-MM-dd", culture);

DateTime.ToString() Patterns
String Format for DateTime [C#]
Convert your string to DateTime and then use DateTime.ToString("yyyy-MM-dd");
DateTime temp = DateTime.ParseExact(sourceDate, "dd-MM-yyyy", CultureInfo.InvariantCulture);
string str = temp.ToString("yyyy-MM-dd");
string sourceDateText = "31-08-2012";
DateTime sourceDate = DateTime.Parse(sourceDateText, "dd-MM-yyyy")
string formatted = sourceDate.ToString("yyyy-MM-dd");
You can write your possible date formats in array and parse date as following:
public static void Main(string[] args)
{
string dd = "12/31/2015"; //or 31/12/2015
DateTime startDate;
string[] formats = { "dd/MM/yyyy", "dd/M/yyyy", "d/M/yyyy", "d/MM/yyyy",
"dd/MM/yy", "dd/M/yy", "d/M/yy", "d/MM/yy", "MM/dd/yyyy"};
DateTime.TryParseExact(dd, formats,
System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.None, out startDate);
Console.WriteLine(startDate.ToString("yyyy-MM-dd"));
}
You can change your Date Format From dd/MM/yyyy to yyyy-MM-dd in following way:
string date = DateTime.ParseExact(SourceDate, "dd/MM/yyyy", CultureInfo.InvariantCulture).ToString("yyyy-MM-dd");
Here, SourceDate is variable in which you will get selected date.
You will need to parse the input to a DateTime object and then convert it to any text format you want.
If you are not sure what format you will get, you can restrict the user to a fixed format by using validation or datetimePicker, or some other component.
This is your primary problem:
The source date could be anything like dd-mm-yyyy, dd/mm/yyyy,
mm-dd-yyyy, mm/dd/yyyy or even yyyy-MM-dd.
If you're given 01/02/2013, is it Jan 2 or Feb 1? You should solve this problem first and parsing the input will be much easier.
I suggest you take a step back and explore what you are trying to solve in more detail.
Try this code:
lblUDate.Text = DateTime.Parse(ds.Tables[0].Rows[0]["AppMstRealPaidTime"].ToString()).ToString("yyyy-MM-dd");
if (DateTime.TryParse(datetoparser, out dateValue))
{
string formatedDate = dateValue.ToString("yyyy-MM-dd");
}
string sourceDate = "15/06/2021T00.00.00";
DateTime Date = DateTime.Parse(sourceDate)
string date = Date.ToString("yyyy-MM-dd");
Convert.toDateTime(sourceDate).toString("yyyy-MM-dd");
Convert.ToDateTime((string)item["LeaveFromDate"]).ToString("dd/MM/yyyy")
