I am developing windows application.
In that i have date in the string format as>> fileDate="15/03/2013"
I want it to be get converted into date format as my database field is datetime.
I used following things for it>>
DateTime dt = DateTime.ParseExact(fileDate, "yyyyy-DD-MM", CultureInfo.InvariantCulture);
DateTime dt = DateTime.Parse(fileDate);
Both of these methods proved failure giving me error>>
String was not recognized as a valid DateTime.
What can be mistake?
Is there another technique to do that?
string fileDate = "15/03/2013";
DateTime dt = DateTime.ParseExact(fileDate, "dd/mm/yyyy", CultureInfo.InvariantCulture);
You have to give the date format according to the date string you have to ParseExact. You can see more on Custom DateTime format - MSDN
Change
"yyyy-MM-dd HH:ss"
To
"dd/MM/yyyy"
Your code would be
DateTime dt = DateTime.ParseExact(fileDate, "dd/MM/yyyy", CultureInfo.InvariantCulture);
You should do this:
DateTime dt = DateTime.ParseExact(fileDate, "dd/MM/yyyy",CultureInfo.InvariantCulture);
You must pass in the string for the format ("dd/MM/yyyy") in the same style that you pass in the string fileDate.
u may try with this
SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
Date convertedDate = dateFormat.parse("ur_dateString")
In your current code you are using format "yyyyy-DD-MM" which is wrong since date part require lower case d not upper case D. , Also for year part you are specifying 5 ys, it should be 4, like yyyy, the order according to your date string should be: "dd/MM/yyyy". To be on the safe side you can even use "d/M/yyyy", which would work for single digit or double digit day/month.
So your code should be:
string fileDate="15/03/2013";
DateTime dt = DateTime.ParseExact(fileDate, "dd/MM/yyyy", CultureInfo.InvariantCulture);

It's because string "15/03/2013" cannot really be parsed as DateTime with format string "yyyy-MM-dd HH:ss".

I have a string like this:
250920111414
I want to create a DateTime object from that string. As of now, I use substring and do it like this:
string date = 250920111414;
int year = Convert.ToInt32(date.Substring(4, 4));
int month = Convert.ToInt32(date.Substring(2, 2));
...
DateTime dt = new DateTime(year, month, day ...);
Is it possible to use string format, to do the same, without substring?
Absolutely. Guessing the format from your string, you can use ParseExact
string format = "ddMMyyyyHHmm";
DateTime dt = DateTime.ParseExact(value, format, CultureInfo.InvariantCulture);
or TryParseExact:
DateTime dt;
bool success = DateTime.TryParseExact(value, format,
CultureInfo.InvariantCulture, DateTimeStyles.None, out dt);
The latter call will simply return false on parse failure, instead of throwing an exception - if you may have bad data which shouldn't cause the overall task to fail (e.g. it's user input, and you just want to prompt them) then this is a better call to use.
EDIT: For more details about the format string details, see "Custom Date and Time Format Strings" in MSDN.
You could use:
DateTime dt = DateTime.ParseExact(
date,
"ddMMyyyyHHmm",
CultureInfo.InvariantCulture);
string iDate = "05/05/2005";
DateTime oDate = Convert.ToDateTime(iDate);
DateTime oDate = DateTime.ParseExact(iString, "yyyy-MM-dd HH:mm tt",null);
DateTime Formats
I want to convert a string of date and time to DateTime structure, but it is giving this error :
String was not recognized as a valid DateTime
DateTime dt = Convert.ToDateTime("5/15/2018 11:54:18 AM");
string date= dt.ToString("HH:mm");
I'm reading this question but I can't solve this code. What is my mistake?
What is the difference between Convert.ToDateTimeand DateTime.ParseExact() in C#?
Based on all the comments, here's how your code should look like
DateTime dt = DateTime.ParseExact("05/15/2018 11:54:18 AM", "MM/dd/yyyy HH:mm:ss tt", CultureInfo.InvariantCulture);
string date = dt.ToString("HH:mm");
What is my mistake?
You Mistake is You are Providing argument Convert.ToDateTime() in a wrong Format.
try Providing "DD/MM/YYYY HH:MM:SS" according to Your system date Time Format .Else you need to use TryParseExatct with Specifying Format
I am using this code to convert a date 03/01/2018 12:00 AM to 2018-03-01 in C#:
DateTime startDate = DateTime.ParseExact(TextBox1.Text.ToString(),
"yyyy-mm-dd",
System.Globalization.CultureInfo.InvariantCulture);
but it throws an exception
String was not recognized as valid datetime
This Will Work Like A Charm
string bs = "03/01/2018 12:00 AM";
String startDate = DateTime.ParseExact(bs,"MM/dd/yyyy hh:mm tt",System.Globalization.CultureInfo.InvariantCulture).ToString("yyyy-MM-dd");
Console.WriteLine(startDate);
// Outputs 2018-03-01
You can verify the code here
A DateTime represents a particular point in time. ParseExact is a way of turning a string into a DateTime. By saying ParseExact with "yyyy-mm-dd" you are telling it that the string you are giving it begins with a four digit year, which it doesn't. Fix the format string that you are supplying so that the parse works.
Once you have the value in your DateTime variable, you can use ToString("yyyy-mm-dd") to turn that DateTime back into a string.
Remove AM from your Textbox and edit format string, then your sample code will work.
This line run successfully :
DateTime startDate = DateTime.ParseExact("03/01/2018 12:00", "MM/dd/yyyy hh:mm", System.Globalization.CultureInfo.InvariantCulture);
string inputDate = "03/01/2018 12:00 AM";
string outputDate = DateTime.Parse(inputDate).ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);
string final = Convert.ToString(DateTime.Parse(date, System.Globalization.CultureInfo.InvariantCulture) + TimeSpan.Parse(duration));
Hi, I use the above code to add two date's to eachother. It do work very well on Windows and returns the required format yyyy-MM-dd HH:mm:ss in a correct fashion. HOWEVER, when on Linux building with Mono it returns the following format dd/MM/yyyy HH:mm:ss which is not what I want.
How can I specify that I ONLY want the first formatting and nothing else? I tried playing around with ParseExact but it did not do very well. What I've heard ParseExact should not really be needed for this?
Here is a example of input:
string date = "2014-10-30 10:00:04"; // On windows
string duration = "05:02:10"; // duration to be added to date
Greetings.
Use ToString("yyyy-MM-dd HH:mm:ss") instead of Convert.ToString.
string date = "2014-10-30 10:00:04";
string duration = "05:02:10";
DateTime dt1 = DateTime.Parse(date, CultureInfo.InvariantCulture);
TimeSpan ts = TimeSpan.Parse(duration, CultureInfo.InvariantCulture);
DateTime dtFinal = dt1.Add(ts);
string final = dtFinal.ToString("yyyy-MM-dd HH:mm:ss", CultureInfo.InvariantCulture);
Convert.ToString uses your current culture's date separator, use CultureInfo.InvariantCulture.
Read: Custom Date and Time Format Strings
You can use the ToString() Method of the DateTime object.
var dt = DateTime.Now;
dt.ToString("yyyy-MM-dd HH:mm");
Using your code:
string _final = (DateTime.Parse(date, System.Globalization.CultureInfo.InvariantCulture) + TimeSpan.Parse(duration)).ToString("yyyy-MM-dd HH:mm:ss");
I have a date time string "12-24-2013 15:19:29" which is in "MM-dd-yyyy HH:mm:ss". I want to convert this string to datetime. But the format should not change.ie, it should be the same "MM-dd-yyyy HH:mm:ss" format.
When I used following method,
DateTime dt2 = DateTime.ParseExact(date31strin, "MM-dd-yyyy HH:mm:ss", CultureInfo.InvariantCulture);
the format is changed to "dd-MM-yyyy HH:mm:ss". I have tried some other method also, but still getting this same format.
First, you should be parsing the string to a DateTime and then format it to the second format using ToString() method.
//Convert your string to a DateTime
DateTime dt2 = DateTime.ParseExact(date31strin,
"MM-dd-yyyy HH:mm:ss", CultureInfo.InvariantCulture);
//If you want to change the format
string secondFormat = dt2.ToString("Second format string");
Note: Date is a Date and it does not have a format. If you need to convert the string to a DateTime, first line of code is enough
You are not changing the format.
You are parsing a string into a DateTime object which does not have a format.
When you decide to present the DateTime, you can format it any way you wish.
to parse String to DateTime use method DateTime.TryParse (http://msdn.microsoft.com/cs-cz/library/ch92fbc1%28v=vs.110%29.aspx) and then use DateTime formating (http://msdn.microsoft.com/en-us/library/az4se3k1%28v=vs.110%29.aspx) to output to aspx page
//frndzz if you are using j query and you don't convert date in(MM/dd/yyyy) to //(dd/MM/yyyy) then this code will help you
// i try it and i get the answer
string sd=txtmydate.Text //sd=04/27/2015 (MM-dd-yyyy) format
string [] sdate = sd.Split('-');
string fd = sdate[1];
fd=string.Concat(sdate[1],"-",sdate[0],"-",sdate[2]);
DateTime dt = Convert.ToDateTime(fd);
txtshow.Text = dt.ToString("dd/MM/yyyy");
//txtshow will show you date as 27-04-2015 (dd/MM/yyyy) format
thanks
How to convert string to DateTime:
string iDate = "Absent";
aEmployeeAttendence.Intime = DateTime.Parse(iDate);
