i have a text-box in a detailview and the value of the text-box is a Date but it only shows the Month and Year and it is like this:November 2013 so i want to take this value and convert like this: 20131101. So as you can see, i would like the format to be YYYYMMDD but the day should always be 01 which is the first of the month. So how can i go from this November 2013 to this 20131101? here is my code and i know i have to convert from string to date first:
string myDate = ((TextBox)DetailView1.FindControl("InputDate")).Text.ToString();
Convert it:
TextBox txtInputDate = (TextBox)DetailView1.FindControl("InputDate");
DateTime dt = DateTime.ParseExact(txtInputDate.Text, "MMMM yyyy", CultureInfo.InvariantCulture);
then convert it to string again:
txtInputDate.Text = dt.ToString("yyyyMMdd", CultureInfo.InvariantCulture);
C# is pretty good at parsing stringy dates, you could lean on the build it parsing:
string myDateString = ((TextBox)DetailView1.FindControl("InputDate")).Text.ToString();
DateTime myDate;
if (DateTime.TryParse(myDateString, out myDate)) {
// myDate now contains a proper .NET date.
}
Now you have a proper DateTime, you can output it in any format you like.
DateTime test = DateTime.Parse("November 2013");
Console.WriteLine(test.ToString("yyyyMMdd"));
Use the DateTime.ParseExact() method, like this:
var theParsedDate = DateTime.ParseExact(myDate, "MMMM yyyy",
CultureInfo.InvariantCulture);
Now you can use the parsed date however you wish, convert it to string, send it to database, etc.

I have a textbox in my project where user enters date, like ddmmyyyy. I need to convert it to dd-mm-yyyy format so that I could fetch particular data from database.
You can parse your string to DateTime first and then generate it's string representation with that format.
For example;
var s = "11062016";
var dt = DateTime.ParseExact(s, "ddMMyyyy", CultureInfo.InvariantCulture);
Console.WriteLine(dt.ToString("dd-MM-yyyy", CultureInfo.InvariantCulture));
By the way, I assume you wanna say MM instead of mm since mm specifier is for minutes but MM specifier is for months.
On the other hand, you never told the data you wanna fetch but, it is not a good idea to get DateTime values (if they are) with strings. Use DateTime values to get DateTime data from your database (which most of of RDMS supports), not strings.
Try
string str = "06112016";
DateTime date = new DateTime();
DateTime.TryParseExact(str, "ddMMyyyy", System.Globalization.CultureInfo.InvariantCulture, System.Globalization.DateTimeStyles.None, out date);
string FormattedDate = date.ToString("MM-dd-yyyy");
I want to get the last seen of user and save it to my sql database in mvc5 . I got the last seen in controller with code like this:
users.userlast=DateTime.Now;
and saved to my database in this format "2015-08-06 12:12:13.443". I want to get datetime only format day,month,year, hour and minute.
I can't use something like this,
var dateTime = DateTime.ParseExact("12/02/21 10:56:09", "yy/MM/dd HH:mm", CultureInfo.InvariantCulture);
var text = dateTime.ToString("MMM. dd, yyyy HH:mm");
It did not work because my last seen column is a datetime type not string. What should i do?
Thanks.
Edit:
Like whatsup App., i want to see only hour and minute, not seconds as last seen.
You say that you are storing as a datetime type, in which case the you shouldn't need to convert a string to a DateTime. In fact you shouldn't need to do any parsing.
When you query the database you should get a DateTime, on which you can call the ToString() you want.
to get datetime in format day, month, year, hour and minute only (without seconds, milliseconds), create a new DateTime value before save:
var dt = DateTime.Now;
users.userlast = dt.Date.AddHours(dt.Hour).AddMinutes(dt.Minute);
You don't have to worry about the format you save in the database. When you want to represent it in your specific format you can ToString it accordingly.
I want to get datetime only format day,month,year, hour and minute.
string text = dateTime.ToString("yyyy-MM-dd HH:mm",
CultureInfo.InvariantCulture);
CultureInfo.InvariantCulture is to use your specified culture regardless of the user's current culture.
You can use InvariantCulture because your user must be in a culture that uses a dot instead of a colon:
DateTime.ToString("yyyy-MM-dd HH:mm", CultureInfo.InvariantCulture);
Just do like that
var formattedDateTime = yourLastSeenDateTime.ToString("MMM. dd, yyyy HH:mm", CultureInfo.InvariantCulture);
EDIT: Try this as you mentioned in comments
DateTime dbDate = yourLastSeenDateTime;
DateTime newDateTime = new DateTime(dbDate.Year, dbDate.Month, dbDate.Day, dbDate.Hour, dbDate.Minute, 0);
I have a date string with dd/mm format like 06/03.Now i have to store this string into mysql table column with DATETIME format.
I am getting the problem as How can i add the current year generically because i don't want to hard code it.Subsequently how will i convert it into MySql DATETIME format for saving it.
Please help me .
You can use Parse method of DateTime:
DateTime dateTime = DateTime.Parse("06/03");
UPDATE
For your comment:
Also after parsing into DateTime i am getting date correct but time i
dont want to be 12:00:00 AM instead i want it to be 00:00:00.
12:00:00 AM corresponds to 00:00:00 only. You can verify that by getting Hour property which will return 0 and also TimeOfDay will too return 00:00:00.
Even if you try to parse exact date, it also creates the same format.
DateTime dateTime = DateTime.ParseExact("06/03 00:00:00", "dd/MM hh:mm:ss",
CultureInfo.InvariantCulture);
And you don't need conversion from DateTime object to SQL compliant DateTime object. You can pass the .Net object to SQL writer.
Consider the code:
C#
string s = "06/03";
System.DateTime dateNow = Convert.ToDateTime(s);
will give the output as you required
in VB.Net :
Dim s As String = "06/03"
Dim dateNow As Date = CDate(s)
MsgBox(dateNow)
You could do something like
var some_date = "06/03";
var year = DateTime.Now.Year;
var option = some_date+"/"+year;
Or use any of the string formats to bend it to your needs
More on date string format can be found on this MSDN page.
Edit:
If you want zeroes in the time, like your comment said, you can usit Rohit vats answer and do:
DateTime dateTime = DateTime.Parse("06/03");
var s1 = dateTime.ToString("MM/dd/yy 00:00:00");
// Output: 03/06/14 00:00:00
var s2 = dateTime.ToString("MM/dd/yyyy 00:00:00");
// Output: 03/06/2014 00:00:00
i have textbox that accepts time format like this 12:40 PM but would like to convert it into time format like this 12:40:00 basically without the PM or AM. Here is what i have so far:
string StartTime = ((TextBox)TestDV.FindControl("txtBST")).Text.ToString();
thanks
One option would be to parse into a DateTime and then back to a string:
string s = "12:40 PM";
DateTime dt = DateTime.Parse(s);
string s2 = dt.ToString("HH:mm:ss"); // 12:40:00
Be aware, however, that most operations work better with a DateTime versus a string representation of a DateTime.
First you should parse it to a DateTime, then format it. It sounds like your input format is something like hh:mm tt and your output format is HH:mm:ss. So, you'd have:
string input = "12:40 PM"
DateTime dateTime = DateTime.ParseExact(input, "hh:mm tt",
CultureInfo.InvariantCulture);
string output = dateTime.ToString("HH:mm:ss", CultureInfo.InvariantCulture);
Note that:
I've used DateTime.ParseExact which will throw an exception if the parsing fails; you may want to use DateTime.TryParseExact (it depends on your situation)
I've used the invariant culture for both operations here. I don't know whether or not that's correct for your scenario.
I've used hh:mm, but you might want h:mm... would you expect "1 PM" or "01 PM"?
You don't parse seconds, so that part will always be 0... is that okay?
Since you are bringing it in as a string this is actually kind of easy.
string StartTime = ((TextBox)TestDV.FindControl("txtBST")).Text.ToString();
DateTime dt = new DateTime();
try { dt = Convert.ToDateTime(StartTime); }
catch(FormatException) { dt = Convert.ToDateTime("12:00 AM"); }
StartTime = dt.ToString("HH:mm");
So you bring in your string, and convert it to a date. if the input is not a valid date, this will default it to 00:00. Either way, it gives you a string and a DateTime object to work with depending on what else you need to do. Both represent the same value, but the string will be in 24-Hour format.
Cheers!!
I have a datetime column in database.
DateTime end_date = DateTime.ParseExact("2013-Jan-31", "yyyy-MM-dd", CultureInfo.InvariantCulture);
Why isn't this working?
This is not working because MM would mean January to be 01. If this is the format of the date you're trying to parse, try the format "yyyy-MMM-dd".
Hope this helps
Try like this;
DateTime a = DateTime.ParseExact("2013-Jan-31", "yyyy-MMM-dd", System.Globalization.CultureInfo.InvariantCulture);
Console.WriteLine (a);
Output:
31.01.2013
Look at from MSDN Custom Date and Time Format Strings
To use such a name of the month you need to take "MMM" so it will be
myObject.end_date = DateTime.ParseExact("2013-Jan-31", "yyyy-MMM-dd", System.Globalization.CultureInfo.InvariantCulture);
MM represents a two-digit numerical month (such as "01").
MMM represents the abbreviated month (such as "Jan").
Which means that you need
myObject.end_date = DateTime.ParseExact("2013-Jan-31", "yyyy-MMM-dd", System.Globalization.CultureInfo.InvariantCulture);
See http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx for a list of string format specifiers.
