Convert custom date to mysql datetime

I have a custom date format that I want to convert to Datetime so I can then insert into my database, I tried using Datetime.ParseExact() But I think I'm misunderstanding something as the code throws a System.FormatException.
I have the following date format from a csv
> 6/11/2014 9:00
and I wish to convert it to the mysql datetime format
> 0000-00-00 00:00:00 OR yyyy-MM-dd HH:mm:ss
Notice they haven't included the seconds in the original date so I am unsure (without appending them to the end) how to set all records to just have "00" for seconds as it is not available.
I tried the following which throws an exception
DateTime myDate = DateTime.ParseExact("6/11/2014 9:00", "yyyy-MM-dd HH:mm",
System.Globalization.CultureInfo.InvariantCulture);

first thing you need to convert string to date time and than convert datetime tos tring
string strd = "6/11/2014 9:00";
DateTime dt ;
//convert datetime string to datetime
if(DateTime.TryParse(strd, out dt))
{
//convert datetime to custom datetime format
Console.WriteLine("The current date and time: {0: yyyy-MM-dd HH:mm:ss}",
dt); ;
}
output

I know this is late to answer that but I'm really surprised none of answer consider to use IFormatProvider to prevent a possible parsing error because of / format specifier or considering your string is a standard date and time format for your CurrentCulture or not so you can or can't use DateTime.TryParse(string, out DateTime) overload directly.
First of all, let's look at what DateTime.ParseExact documentation says:
Converts the specified string representation of a date and time to its
DateTime equivalent. The format of the string representation must
match a specified format exactly or an exception is thrown.
In your case, they don't match. You should use d/MM/yyyy H:mm format to parse your example string with a culture that have / as a DateSeparator. I almost always suggest to use DateTime.TryParseExact method in this kind of situations;
string s = "6/11/2014 9:00";
DateTime dt;
if(DateTime.TryParseExact(s, "d/MM/yyyy H:mm", CultureInfo.InvariantCulture,
DateTimeStyles.None, out dt))
{
Console.WriteLine(dt.ToString("yyyy-MM-dd HH:mm:ss"));
// result will be 2014-11-06 09:00:00
}

If you know formats of your dates, then you can do this:
string stringDate = "6/11/2014 9:00";
//Your date formats of input
string[] dateFormats = new string[]
{
"d/MM/yyyy H:mm",
"dd/MM/yyyy H:mm",
"dd/MM/yyyy HH:mm",
"dd/MM/yyyy H:mm:ss",
"dd/MM/yyyy HH:mm:ss"
/* And other formats */
};
DateTime convertedDate;
bool isSuccessful = DateTime.TryParseExact(stringDate, dateFormats,
System.Globalization.CultureInfo.InvariantCulture, System.Globalization.DateTimeStyles.None, out convertedDate);
if (isSuccessful)
{
//If conversion was successful then you can print your date at any format you like
//because you have your date as DateTime object
Console.WriteLine(convertedDate.ToString("dd-MM-yyyy HH:mm:ss")); /* Or other format you want to print */
}
I hope it will be helpful to you.

Converting string to date in another culture

I am trying to convert a string (which represents date in invariantCulture) to dateTime in given culture. The problem is that when the date is converted to German culture, the day becomes month and month becomes day.
What is wrong with below code or am i missing something ?
var day = 11; var month = 12; var year = 2014;
var someDate = new DateTime(year, month, day);
var theDay = someDate.Day;//11 ok as expected
var theMonth = someDate.Month; //12 ok as expected
var dateString = someDate.ToString(CultureInfo.InvariantCulture);
var date1 = DateTime.Parse(dateString, CultureInfo.GetCultureInfo("de-De"));
var day1 = date1.Day;//12 this should be 11 ?
var month1 = date1.Month; //11 this should be 12 ?

The second argument to DateTime.Parse is used to tell the parser what format the string is in, not what format you want to convert it to. You are generating an invariant string and then parsing it as a German string which is why your day and month are getting swapped.
If your goal is to get a German string representation of the date, just use var dateString = someDate.ToString(CultureInfo.GetCultureInfo("de-DE")).

I guess de-De culture doesn't have a standard date and time format as MM/dd/yyyy HH:mm:ss.
Since you using DateTime.ToString() method with InvariantCulture, result string will be "G" standard format which is MM/dd/yyyy HH:mm:ss for InvariantCulture.
Because of that, dateString will be 12/11/2014 00:00:00 and de-DE culture doesn't have a standard date and time format MM/dd/yyyy HH:mm:ss but has dd/MM/yyyy HH:mm:ss which is dd.MM.yyyy HH:mm:ss for de-DE culture.
That's why DateTime.Parse method matches pattern which is dd/MM/yyyy HH:mm:ss (since it's DateSeparator is . it should be dd.MM.yyyy HH:mm:ss format).
That's why it parses your 12 as a Day and 11 as a Month.
If you already a DateTime (which you have) just use .ToString() method with your de-DE culture like;
var culture = new CultureInfo("de-De");
var dateString = someDate.ToString(culture);
Remember, a DateTime doesn't have any implicit format or culture. It just have date and time values. String representations of them can have formats.
By the way, you can find all standard date and time patterns your de-DE culture like;
var culture = new CultureInfo("de-De");
foreach (var format in culture.DateTimeFormat.GetAllDateTimePatterns())
{
Console.WriteLine(format);
}

Change the following line and test it again:
var dateString = someDate.ToString(CultureInfo.InvariantCulture);
to:
var dateString = someDate.ToString("O");
or:
var dateString = someDate.ToString("S");

ok, here is what i think what you want to accomplish, not sure if i got you right: you want to read an invariant cultured date string and convert it to a german cultured date string.
but in your example you are trying to parse an invariant cultured date AS a german cultured date. of course that leads to a misinterpretation. try this:
string invariantCultureDateString = "12/11/2014 00:00:00";
var dateTime = DateTime.Parse(invariantCultureDateString, CultureInfo.InvariantCulture);
string germanCultureDateString = dateTime.ToString(CultureInfo.GetCultureInfo("de-De"));

ASP.NET format string date

I am connecting to a database, executing a query, and putting the data in a list. I have strings that have dates like so mm/dd/yyyy hour:minute:second AM or PM I am looking to format this data into yyyy-mm-dd with no time.
This is where I am assigning the data:
airportItems.ContractReceived_F = dataReader.GetValue(1).ToString();
how would I convert the dataReader.GetValue(1).ToString(); to the date format I want?
I have tried the following:
airportItems.ContractReceived_F = string.Format("{0:d}", dataReader.GetValue(1).ToString());
I am defining ContractReceived_F as string:
public string ContractReceived_F { get; set; }
and it still returned the time.

Use this:
airportItems.ContractReceived_F = dataReader.GetDateTime(1).ToString("yyyy-MM-dd");
where yyyy represents the year, MM represents the month and dd represents the day.

why not parse the data you need to like this
DateTime unparsed_date = mydatevalue; //any date in any date format
string parsed_date = unparsed_date.toString("dd mm yyyy");
Theres an article on the different parses on msdn that i found for you
check it out
Credit goes to fubo for the link (thumbs up)

I suggest to use the TryParseExact
Then you choose the date format that you need
For example :
DateTime OutputDate = null;
DateTime.TryParseExact(DateFromTheView, "yyyy/MM/dd H:mm:ss tt", System.Globalization.CultureInfo.InvariantCulture, DateTimeStyles.None, out OutputDate);
In the example : the format is "yyyy/MM/dd H:mm:ss tt" and the input date string is DateFromTheView. The OutputDate will take as value the new datetime object and if the instruction fails it will take null.

DateTime.ParseExact throws System.FormatException

Why this line of code sometimes throws System.FormatException?
DateTime d = DateTime.ParseExact("01.07.2014", "dd/MM/yyyy", CultureInfo.InvariantCulture);

Because your string and format doesn't match.
From documentation;
Converts the specified string representation of a date and time to its
DateTime equivalent using the specified format and culture-specific
format information. The format of the string representation must match
the specified format exactly.
Use dd.MM.yyyy format instead.
DateTime d = DateTime.ParseExact("01.07.2014",
"dd.MM.yyyy",
CultureInfo.InvariantCulture);
Here a demonstration.
Remember, "/" custom format specifier has a special meaning in custom date and time formats. It means as; replace me with the current culture date separator.
In your profile, it says you are from Azerbaijan. That means your CurrentCulture is probably az-Cyrl-AZ (Cyrillic, Azerbaijan) or az-Latn-AZ (Latin, Azerbaijan).
Actually, doesn't matter which culture you use on this case because both culture has . as a DateSeparator property.
That means your original code also works with your CurrentCulture.
DateTime d = DateTime.ParseExact("01.07.2014",
"dd/MM/yyyy",
CultureInfo.CurrentCulture);
// or you can use null
For more information, take a look;
Custom Date and Time Format Strings

You need a culture where "." is the DateSeparator, for example:
DateTime d = DateTime.ParseExact("01.07.2014", "dd/MM/yyyy",
CultureInfo.GetCultureInfo("az-Cyrl-AZ"));
if you are in Azerbaijan and use Azerbaijani language with the Cyrillic script.
You can use:
DateTime d = DateTime.ParseExact("01.07.2014", "dd/MM/yyyy",
null);
to just take the current culture.
Maybe you just need "d" instead of the verbose "dd/MM/yyyy", since the standard short date format in Azerbaijani is just like "01.07.2014".
The "invariant culture" uses "/" as its DateSeparator, so therefore you should not use it in your case.
Also, this works:
DateTime d = DateTime.ParseExact("01.07.2014", "dd/MM/yyyy",
new DateTimeFormatInfo { DateSeparator = ".", }
);
because new DateTimeFormatInfo() makes a read/write "invariant-culture" date/time info for which you can change the relevant property.

The / in the date format will match the date separator of the culture that you specify. If you use a culture that has period as date separator, the parsing will work.
Example:
DateTime d = DateTime.ParseExact("01.07.2014", "dd/MM/yyyy", CultureInfo.GetCultureInfo("de"));
You can also use a literal period instead of the date separator specificer, then it works with the invariant culture:
DateTime d = DateTime.ParseExact("01.07.2014", "dd.MM.yyyy", CultureInfo.InvariantCulture);
Ref: Custom Date and Time Format Strings

The format you have is different from the string provided:
Try either of the below, it will work :)
DateTime d1 = DateTime.ParseExact("01/07/2014", "dd/MM/yyyy", CultureInfo.InvariantCulture);
DateTime d2 = DateTime.ParseExact("01.07.2014", "dd.MM.yyyy", CultureInfo.InvariantCulture);

Problem:
Your separator in date is . while in string format it is /
Solution:
Your format should be "dd.MM.yyyy" or "MM.dd.yyyy" as your date is "01.07.2014". 01 and 07 exist both as date and month.
This date can be 01st July 2014 or 07 Jan 2014.
Your code should be
DateTime d = DateTime.ParseExact("01.07.2014",
"dd.MM.yyyy",
CultureInfo.InvariantCulture);
OR
DateTime d = DateTime.ParseExact("01.07.2014",
"MM.dd.yyyy",
CultureInfo.InvariantCulture);

Datetime format Issue: String was not recognized as a valid DateTime

I want to format the input string into MM/dd/yyyy hh:mm:ss format in C#.
The input string is in format MM/dd/yyyy hh:mm:ss
For example :"04/30/2013 23:00"
I tried Convert.ToDateTime() function, but it considers 4 as date and 3 as month which is not what I want. Actually month is 04 and date is 03.
I tried DateTime.ParseExact() function also, But getting Exception.
I am getting error:
String was not recognized as a valid DateTime.

Your date time string doesn't contains any seconds. You need to reflect that in your format (remove the :ss).
Also, you need to specify H instead of h if you are using 24 hour times:
DateTime.ParseExact("04/30/2013 23:00", "MM/dd/yyyy HH:mm", CultureInfo.InvariantCulture)
See here for more information:
Custom Date and Time Format Strings

You can use DateTime.ParseExact() method.
Converts the specified string representation of a date and time to its
DateTime equivalent using the specified format and culture-specific
format information. The format of the string representation must match
the specified format exactly.
DateTime date = DateTime.ParseExact("04/30/2013 23:00",
"MM/dd/yyyy HH:mm",
CultureInfo.InvariantCulture);
Here is a DEMO.
hh is for 12-hour clock from 01 to 12, HH is for 24-hour clock from 00 to 23.
For more information, check Custom Date and Time Format Strings

try this:
string strTime = "04/30/2013 23:00";
DateTime dtTime;
if(DateTime.TryParseExact(strTime, "MM/dd/yyyy HH:mm",
System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.None, out dtTime))
{
Console.WriteLine(dtTime);
}

This can also be the problem if your string is 6/15/2019. DateTime Parse expects it to be 06/15/2019.
So first split it by slash
var dateParts = "6/15/2019"
var month = dateParts[0].PadLeft(2, '0');
var day = dateParts[1].PadLeft(2, '0');
var year = dateParts[2]
var properFormat = month + "/" +day +"/" + year;
Now you can use DateTime.Parse(properFormat, "MM/dd/yyyy"). It is very strange but this is only thing working for me.

change the culture and try out like this might work for you
string[] formats= { "MM/dd/yyyy HH:mm" }
var dateTime = DateTime.ParseExact("04/30/2013 23:00",
formats, new CultureInfo("en-US"), DateTimeStyles.None);
Check for details : DateTime.ParseExact Method (String, String[], IFormatProvider, DateTimeStyles)

DateTime dt1 = DateTime.ParseExact([YourDate], "dd-MM-yyyy HH:mm:ss",
CultureInfo.InvariantCulture);
Note the use of HH (24-hour clock) rather than hh (12-hour clock), and the use of InvariantCulture because some cultures use separators other than slash.
For example, if the culture is de-DE, the format "dd/MM/yyyy" would expect period as a separator (31.01.2011).

Below code worked for me:
string _stDate = Convert.ToDateTime(DateTime.Today.AddMonths(-12)).ToString("MM/dd/yyyy");
String format ="MM/dd/yyyy";
IFormatProvider culture = new System.Globalization.CultureInfo("fr-FR", true);
DateTime _Startdate = DateTime.ParseExact(_stDate, format, culture);

You may use this type format (get formatted data from sql server)
FORMAT(convert(datetime,'16/04/2018 10:52:20',103),'dd/MM/yyyy HH:mm:ss', 'en-us')
CONVERT(VARCHAR,convert(datetime,'16/04/2018 10:52:20',103), 120)
