DateTime dt = DateTime.Now
dt.Date is created to 31.10.2012 00:00:00 .it is created to dd.mm.yyyy format but i need dd/mm/yyyy. Can i use: return new DateTime(d.Year, d.Month, d.Day, 0, 0, 0); it will create to me dd/mm/yyyy solution?Please dont translate String.i need datetime...
The DateTime struct doesn't store any formatting information internally. If you want to output the DateTime instance as a formatted string, you just need to call ToString() with the proper format string:
var date = DateTime.Now;
var formattedString = date.ToString("dd/MM/yyyy", CultureInfo.InvariantCulture);
If you need more information on exactly which specifiers to use in your format string, check out:
MSDN - Custom Date and Time Format Strings
Just the way to convert to string, DateTime itself has no format:
var result = DateTime.Now.Date
.ToString("dd/MM/yyyy", CultureInfo.InvariantCulture);
var dt = DateTime.Now;
var stringDt = dt.Date.ToString("dd/MM/yyyy");
In you case you can simply use :
dt.ToString("dd/MM/yyyy");
Anyway there al the string format you can use with DateTime : Here.
System.DateTime does not have any format. You can view its string representation in format.
Try this
Console.WriteLine(DateTime.Now.Date.ToString("dd'/'MM'/'yyyy"));
DateTime, numeric types and most other types do not store their values in a formatted way. Rather they store their data using a binary representation. If you want to display this data to the user, you must convert it to a string. This conversion involves formatting the data.
string formattedDate = DateTime.Now.ToString("dd/MM/yyyy",
CultureInfo.InvariantCulture);
Or
Console.WriteLine("Date = {0:dd/MM/yyyy}", DateTime.Now);
Console.WriteLine converts the date into a string in order to write it to the console.
DateTime structure always has the Date and Time stored in it. If you need to extract the date alone as text you can do the following.
var date = DateTime.Now.ToString("d");
Console.WriteLine(date);
This will print the date as in the format as specified by the culture set in the system. The list of standard datetime format strings supported by dotnet framework can be found here

I am querying SharePoint and my dates are returned as YYYY-MM-dd 16:27:12 - for display only I tried to modify the syntax to be
string dateInfo = xNode.Attributes[“Altered”].Value;
sb.Append(String.Format(“{0:MM/dd/yyyy}”, dateInfo));
However that is not formatting the date time. What do i need to change so that the date/time is returned in my required format?
My desired format is mm/dd/yyyy 4:27:12 12 hour format so
You have to parse it to DateTime first:
string dateInfo = xNode.Attributes["Altered"].Value;
DateTime dt = DateTime.Parse(dateInfo);
sb.Append(String.Format("{0:MM/dd/yyyy}", dt));
Try, like:
var result = DateTime.Parse(dateInfo).ToString("MM/dd/yyyy");
I have a string representing a date in a certain format, that I wish to format differently. Someone told me to use DateTime.(Try)ParseExact, so I did:
var dateString = "2016-02-26";
var formatString = "dd/MM/yyyy";
var parsedDate = DateTime.ParseExact(dateString, formatString, null);
You see, I want to format the date as dd/MM/yyyy, so 26/02/2016. However, this code throws a FormatException:
String was not recognized as a valid DateTime.
How can I format a DateTime differently?
First of all, DateTimes have no format. A DateTime holds a moment in time and a flag indicating whether that moment is Local, Utc or Unspecified.
The only moment a DateTime gets formatted, is when you output its value as a string.
The format string you provide to (Try)ParseExact is the format that the date(time) string to parse is in. See MSDN: Custom Date and Time Format Strings to learn how you can write your own format string.
So the code you're looking for to parse that string is this, and again, make sure the format string matches the format of the input date string exactly:
var dateString = "2016-02-26";
var formatString = "yyyy-MM-dd";
var parsedDate = DateTime.ParseExact(dateString, formatString, null);
Now parsedDate holds a DateTime value that you can output in your desired format (and note that you'll have to escape the /, as it'll be interpreted as "the date separator character for the current culture", as explained in above MSDN link):
var formattedDate = parsedDate.ToString("dd\\/MM\\/yyyy");
This will format the date in the desired format:
26/02/2016
You can use this for String date
DateTime.ParseExact(dateString, format, provider);
and for provider value
CultureInfo provider = CultureInfo.InvariantCulture;
as mentioned in Microsoft documentation
I'm having a troubles with converting strings to DateTime. Here is what I have. First I convert current date to string (this will be folder name).
string dateString = string.Format("{0:yyyy-MM-dd_HH-mm-ss}", DateTime.Now);
Output like this
2013-05-16_09-32-47
Then I create a folder. During program execution I get this folder and I need to convert it's name back to DateTime. Try to make it like this
DateTime directoreDate = DateTime.ParseExact(directory.Name, "0:yyyy-MM-dd_HH-mm-ss", CultureInfo.InvariantCulture);
But it throws FormatException. Can anybody tell me why this happening.
You are using the same composite format string that you used to format the original DateTime. This is not needed for ParseExact - drop the 0: from it:
DateTime directoreDate = DateTime.ParseExact(directory.Name,
"yyyy-MM-dd_HH-mm-ss",
CultureInfo.InvariantCulture);
Use
DateTime directoreDate = DateTime.ParseExact(directory.Name, "yyyy-MM-dd_HH-mm-ss", CultureInfo.InvariantCulture);
Remove 0: from DateTime.ParseExact, It was used as a place holder in string.Format().
Use as :
DateTime directoreDate = DateTime.ParseExact(directory.Name,
"yyyy-MM-dd_HH-mm-ss",
CultureInfo.InvariantCulture);
I have a conversion problem with datetime. I have a date string as MM/dd/yyyy. Now I need to convert it to yyyy-MM-dd.
But I'm facing some error. Please help
public static DateTime ToDBDateTime(string _dateTime)
{
string sysFormat = "MM/dd/yyyy hh:mm:ss tt";
string _convertedDate = string.Empty;
if (_dateTime != null || _dateTime != string.Empty)
{
_convertedDate = DateTime.ParseExact(_dateTime, sysFormat, System.Globalization.CultureInfo.InvariantCulture).ToString(_toDBDateFormat);
//_convertedDate = Convert.ToDateTime(_dateTime).ToString(_toDBDateFormat);
/// Debug.Print(sysFormat);
}
return Convert.ToDateTime(_convertedDate);
}
And I want to know that is there is any way to pass the datetime in various formats and it would return the expected format.
E.g.: if I pass date as dd/MM/yyyy or MM/dd/yyyy, the above function would return the date in format as yyyy-MM-dd.
Please provide some suggestion to solve datetime issues.
I have a date string as MM/dd/yyyy
Right... and yet you're trying to parse it like this:
string sysFormat = "MM/dd/yyyy hh:mm:ss tt";
...
_convertedDate = DateTime.ParseExact(_dateTime, sysFormat,
CultureInfo.InvariantCulture)
You need to give a format string which matches your input - so why are you including a time part? You probably just want:
string sysFormat = "MM/dd/yyyy";
However, that's not the end of the problems. You're then converting that DateTime back into a string like this:
.ToString(_toDBDateFormat)
... and parsing it once more:
return Convert.ToDateTime(_convertedDate);
Why on earth would you want to do that? You should avoid string conversions as far as possible. Aside from anything else, what's to say that _toDBDateFormat (a variable name which raises my suspicions to start with) and Convert.ToDateTime (which always uses the current culture for parsing) are going to be compatible?
You should:
Work out how you want to handle being given an empty string or null, and just return an appropriate DateTime then
Otherwise, just parse using the right format.
This part of your question also concerns me:
E.g.: if I pass date as dd/MM/yyyy or MM/dd/yyyy, the above function would return the date in format as yyyy-MM-dd.
There's no such thing as "the date in format as yyyy-MM-dd". A DateTime is just a date and time value. It has no intrinsic format. You specify how you want to format it when you format it. However, if you're using the value for a database query, you shouldn't be converting it into a string again anyway - you should be using parameterized SQL, and just providing it as a DateTime.
As you have a date in a string with the format "MM/dd/yyyy" and want to convert it to "yyyy-MM-dd" you could do like this:
DateTime dt = DateTime.ParseExact(dateString, "MM/dd/yyyy", CultureInfo.InvariantCulture);
dt.ToString("yyyy-MM-dd");
Use the inbuilt tostring like this:
Convert.ToDateTime(_convertedDate).ToString("MM/dd/yyyy") or whatever format you want.
I tried this and its working fine.
DateTime date1 = new DateTime(2009, 8, 1);
date1.ToString("yyyy-MM-dd hh:mm:ss tt");
You can apply any format in this ToString.
Hope that helps

I have a date that is stored as a string in the format YYYYDDMM. I would like to display that value in a 'MM/DD/YYYY' format. I am programming in c#. The current code that I am using is as follows:
txtOC31.Text = dr["OC31"].ToString().Trim();
strOC31date = dr["OC31DATE"].ToString().Trim();
DateTime date31 = DateTime.Parse(strOC31date);
strOC31date = String.Format("{0:MM/dd/yyyy}", date31);
However, I am getting an error because the YYYYMMDD string (strOC31date) is not being recognized as a valid datetime.
DateTime.ParseExact with an example
string res = "20120708";
DateTime d = DateTime.ParseExact(res, "yyyyddMM", CultureInfo.InvariantCulture);
Console.WriteLine(d.ToString("MM/dd/yyyy"));
Use ParseExact() (MSDN) when the string you are trying to parse is not in one of the standard formats. This will allow you to parse a custom format and will be slightly more efficient (I compare them in a blog post here).
DateTime date31 = DateTime.ParseExact(strOC31date, "yyyyMMdd", null);
Passing null for the format provider will default to DateTimeFormatInfo.CurrentInfo and is safe, but you probably want the invariant culture instead:
DateTime date31 = DateTime.ParseExact(strOC31date, "yyyyMMdd", DateTimeFormatInfo.InvariantInfo);
Then your code will work.
Instead of DateTime.Parse(strOC31date); use DateTime.ParseExact() method, which takes format as one of the parameters.
You want the method DateTime.ParseExact.
DateTime date31 = DateTime.ParseExact(strOC31date, "yyyyddMM", CultureInfo.InvariantCulture);
