My system date format is dd-MM-yyyy(20-10-2012) and I'm getting the date and using separator to split the date, month and year. I need to convert date format (dd/MM/yyyy) whether the formats returns at any date format.
string sDate = string.Empty;
DateTime _date = DateTime.Now;
int count = 0;
string format = "dd-MM-yyyy";
sDate = dateFormat.ToString(format);
string[] Words = sDate.Split(new char[] { '-' });
foreach (string Word in Words)
{
count += 1;
if (count == 1) { Day = Word; }
if (count == 2) { Month = Word; }
if (count == 3) { Year = Word; }
}
Here is what you are looking for:
String sDate = DateTime.Now.ToString();
DateTime datevalue = (Convert.ToDateTime(sDate.ToString()));
String dy = datevalue.Day.ToString();
String mn = datevalue.Month.ToString();
String yy = datevalue.Year.ToString();
OR
Alternatively, you can use split function to split string date into day, month and year here.
Hope, it will helps you... Cheers. !!
You can do like follow:
String date = DateTime.Now.Date.ToString();
String Month = DateTime.Now.Month.ToString();
String Year = DateTime.Now.Year.ToString();
On the place of datetime you can use your column..
You can split date month year from current date as follows:
DateTime todaysDate = DateTime.Now.Date;
Day:
int day = todaysDate.Day;
Month:
int month = todaysDate.Month;
Year:
int year = todaysDate.Year;
You should use DateTime.TryParseExcact if you know the format, or if not and want to use the system settings DateTime.TryParse. And to print the date,DateTime.ToString with the right format in the argument. To get the year, month or day you have DateTime.Year, DateTime.Month or DateTime.Day.
See DateTime Structures in MSDN for additional references.
Without opening an IDE to check my brain works properly for syntax at this time of day...
If you simply want the date in a particular format you can use DateTime's .ToString(string format). There are a number of examples of standard and custom formatting strings if you follow that link.
So
DateTime _date = DateTime.Now;
var _dateString = _date.ToString("dd/MM/yyyy");
would give you the date as a string in the format you request.
TL&DR; The DateTime Object in C# has the ability to extract the string information using the ToString() function with the correct format string. (ie: "yyyy-mm-dd");
string onlyDateWithoutTimeStamp = lastDate.ToString("yyyy-MM-dd");

I got every part of date in the code that you can see below. But the problem is if we consider today's date I need day and month as 02 not as 2.
I need that 0 char in the beggining. How can I manage it?
DateTime dategift = DateTime.Now;
var year = dategift.Year.ToString();
var month = dategift.Month.ToString();
var day = dategift.Day.ToString();
var hour = dategift.Hour.ToString();
var min = dategift.Minute.ToString();
var sec = dategift.Second.ToString();
use the Zero placeholder
string day = dategift.Day.ToString("00");
or the "dd" custom format specifier
string day = dategift.ToString("dd");
If you're wanting to format the date, you can do so without pulling out all the various values as strings.
Something like:
DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss.fff");
I trying to parse a string like 4212021 where 4 is the month, 21 is the day, and 2021 is the year, into a DateTime object. I've tried using the following code but for some reason I am getting 'String '4212021' was not recognized as a valid DateTime.':
string datetimestring = "4122021";
var date = DateTime.ParseExact(datetimestring, "Mddyyyy", CultureInfo.InvariantCulture, DateTimeStyles.AssumeLocal);
All help is appreciated. Thanks.
This doesn't work without date separators. So you could add them:
string format = "Mddyyyy";
CultureInfo culture = CultureInfo.InvariantCulture;
string separator = culture.DateTimeFormat.DateSeparator;
if(datetimestring.Length >= format.Length)
{
int firstIndex = datetimestring.Length % 2 == 0 ? 2 : 1;
datetimestring = datetimestring.Insert(firstIndex, separator);
datetimestring = datetimestring.Insert(firstIndex + 2 + separator.Length, separator);
}
DateTime date = DateTime.Parse(datetimestring, culture, DateTimeStyles.None);
This works also if the month has two digits like in "12122021".
Another, maybe simpler way was to use ParseExact with "Mddyyyy HHmmss" and append zero time:
datetimestring = datetimestring + " 000000"; // check first length ofc
DateTime date = DateTime.ParseExact(datetimestring, "Mddyyyy HHmmss", culture, DateTimeStyles.None);
It's just the "M" modificator that does not work if you use it without separators AND with variable length. If you ensure leading zeros, it should work. ("04" instead of "4")
string datetimestring = 4122021.ToString("D8");
var date = DateTime.ParseExact(datetimestring, "Mddyyyy", CultureInfo.InvariantCulture, DateTimeStyles.AssumeLocal);
Since your day is always 2 digits (dd) you can just append a 0 to the start of the string when the month only has 1 digit, and use the MM for month:
string datetimestring = "4122021";
var date = DateTime.ParseExact(datetimestring.PadLeft(8,'0'), "MMddyyyy", CultureInfo.InvariantCulture, DateTimeStyles.AssumeLocal);
I am imagining you have a special reason for not changing the input. You can try this way, it will work.
string datetimestring = "4122021";
var date = DateTime.ParseExact(datetimestring.Length < 8 ? $"0{datetimestring}" : datetimestring, "Mddyyyy", CultureInfo.InvariantCulture, DateTimeStyles.AssumeLocal);
See if it is appropriate for your context?
All of my friend.
I want to convert informal string to dateTime in c#. Here my string value is "01042016".How can convert? can i need another step to change DateTime.
This is my code:
string FinancialYear = "01042016-31032017";
string[] splitDate = FinancialYear.Split('-');
DateTime startDate = Convert.ToDateTime(splitDate[0].ToString(),"dd/MM/yyyy"));
As we can see that the input date will be in the format ddMMyyyy so here the best option for converting the input to DateTime object is DateTime.TryParseExact the code for this will be :
string FinancialYear = "01042016-31032017";
string[] splitDate = FinancialYear.Split('-');
DateTime startDate ;
if(DateTime.TryParseExact(splitDate[0],"ddMMyyyy",CultureInfo.InvariantCulture,DateTimeStyles.None,out startDate))
{
// Proceed with the startDate it will have the required date
}
else
// Show failure message
This will create an Enumerable where index 0 is the first date and index 1 is the second date.
string FinancialYear = "01042016-31032017";
var dateRange = FinancialYear.Split('-')
.Select(d => DateTime.ParseExact(d, "ddMMyyyy", CultureInfo.InvariantCulture);
If you are not sure of the format your best bet is using DateTime.Parse() or DateTime.TryParse()
You are not 100% guaranteed that the date will be parsed correctly, especially in cases where the day and month numbers could be in the wrong order.
It is best to specify a required date format if you can so you can be sure the date was parsed correctly.
if you string is in static format, you can convert it by reconvert it to valid string format first such as
string validstring = splitDate[0].ToString().Substring(4,4)+"-"+splitDate[0].ToString().Substring(2,2) +"-"+ splitDate[0].ToString().Substring(0,2);
DateTime startDate = Convert.ToDateTime(validstring,"dd/MM/yyyy"));
I have a string which contains a date and time. Date is in any of the following formats:
"M/D/YYYY" or "MM/D/YYYY" or "M/DD/YYYY" or "MM/DD/YYYY".
And time is either in:
"hh:mm:ss" or "h:mm:ss".
The string is retrieved from SQL Server in C# code.
How do I convert this into a string containing date in the format "CCYYMMDD"?
var inputDate = "4/28/2006 12:39:32:429AM";
//1 - parse into date parts
char[] delimiterChars = { '/' };
string[] dateParts = inputDate.Split(delimiterChars);
var month = int.Parse(dateParts[0].ToString());
var day = int.Parse(dateParts[1].ToString());
var year = 0;
string yearString = dateParts[2].ToString();
//strip of the time for the year part
if (yearString.Length > 5)
year = int.Parse(yearString.Substring(0, 4));
//2 - Create date object
DateTime testDate = new DateTime(year, month, day);
//3 - format date
var outputDate = testDate.ToString("yyyyMMdd");
Console.WriteLine("Input date: " + inputDate);
Console.WriteLine("Output date: " + outputDate);
Console.ReadLine();
You can refer to MSDN for formatting dates here . You may also want to do some validation to ensure you're getting a valid date from SQL Server.
Actually, this way is better. I don't know what I was thinking before.. use the DateTime.TryParse method validate if the string is a date. If TryParse comes back as false, the string is not in a valid date format. The format you are expecting in your requirement are valid date formats.
DateTime date;
var inputDate = "4/28/2006 12:39:32";
var outputDate = "Could not format the date. The input date is not in a correct date format!";
if (DateTime.TryParse(inputDate,out date))
{
outputDate = date.ToString("yyyyMMdd");
}
Console.WriteLine("Input date: " + inputDate);
Console.WriteLine("Output date: " + outputDate);
Console.ReadLine();
In my database, date is stored as dd/mm/yyyy. When I retrieve it I want to split the date in string day, string month and string year respectively. How should I go about doing it? "/" will be the delimiter is that right?
You need can use DateTime.ParseExact with format "dd/MM/yyyy": (Where myString is the birthday from the database.)
string myString = "01/02/2015"; // From Database
DateTime birthday = DateTime.ParseExact(myString, "dd/MM/yyyy", CultureInfo.InvariantCulture);
int year = birthday.Year;
int month = birthday.Month;
int day = birthday.Day;
You can then use the DateTime object to get the year, month, day, etc.
Using string.Split is an option too, but storing as a DateTime allows you to use many handy methods/properties it contains, but you can do it using string.Split as so:
string[] birthday = myString.Split('/');
int year, month, day;
int.TryParse(birthday[0], out day);
int.TryParse(birthday[1], out month);
int.TryParse(birthday[2], out year);
If you get birthDate from database as string, you can use split function to split that string into array like:
string birthDate = "2015/02/01";
var split = birthDate.Split('/');
If you get birthDate from database as datetime, you can extract date parts from it like:
DateTime birthDate = DateTime.Now.Date;
var year = birthDate.Year;
var month = birthDate.Month;
var day = birthDate.Day;
