I have a string which value is "2016-01-07 20:43:01,803".
I'd like to convert it use DateTime.Parse method. it is failed.
How to convert to datetime with this type of string?

You could use the ParseExact method.
var input = "2016-01-07 20:43:01,803";
DateTime dt = DateTime.ParseExact(input, "yyyy-MM-dd HH:mm:ss,fff", CultureInfo.InvariantCulture);

Try to use DateTime.ParseExact with the right format. (the last phrase is very very important: right format)
DateTime dt = DateTime.ParseExact("2016-01-07 20:43:01,803", "yyyy-MM-dd HH:mm:ss,fff", null);

I have tried following way but doesn't work
dateTime="2018-12-13T07:33:35.893Z"
DateTime dt;
DateTime.TryParseExact(dateTime, out dt);
But I am always getting dt as {1/1/0001 12:00:00 AM}.
Can you please tell me why? and how can I convert that string to date?
I also tried Convert.ToDateTime but doesn't work.
What I actually want is getting the dd/MM/yyyy string'd DateTime so I could perform a query on a DB.
Have you got the original DateTime object or you simply have it in a string?
In case you've got it as DateTime:
string european = dateTime.ToString("dd/MM/yyyy");
In case you've got it as a string:
string date = "2018-12-13T07:33:35.893Z";
if(DateTime.TryParse(date , out DateTime result))
result.ToString("dd/MM/yyyy");
Have a look at the original MSDN documentation about the DateTime.ToString method
Since you've got a DateTime you can convert to that format:
var thisExactMoment = DateTime.Now;
thisExactMoment.ToString("dd/MM/yyyy");
With your "dateTime" variable, just perform dateTime.ToString("dd/MM/yyyy") and you're ready to go.
var dateTime = "2018-12-13T07:33:35.893Z";
var x = DateTime.Parse(dateTime).ToString(#"MM\/dd\/yyyy");

Convert string to DateTime in c#

I have a string that is a date in the format of "MMddyyyy". I need to convert it to a DateTime with formatting "dd/MM/yyyy". I created the following code, but I keep getting a Format Exception. Parse, ParseExact, TryParseExact all give a Format Exception also.
string dater = "10312016";
DateTime condate = Convert.ToDateTime(dater);
I have tried the following:
string dater = "10312016";
DateTime condate = DateTime.ParseExact(dater, "MMddyyyy", CultureInfo.InvariantCulture);
DateTime condate2 = DateTime.ParseExact(dater, "yyyyMMdd", CultureInfo.InvariantCulture);
condate works, but it is in the wrong format. It needs to be "dd/MM/yyyy"
string dater = "10312016";
DateTime condate = Convert.ToDateTime(dater).tostring("dd/MM/yyyy");
Just try this. I am posting answer from my mobile. So tostring syntax may not right. When u type tostring in IDE then it will be alright.
Edit
sorry for later answer. see this code and it is working.
string dater = "10312016";
DateTime condate = DateTime.ParseExact(dater, "MMddyyyy", System.Globalization.CultureInfo.InvariantCulture);
string strDate = condate.ToString("dd/MM/yyyy");

Convert string "Jun 1 2005 1:33PM" into datetime

I need to convert a string with date to valid c# date time object.
input string example = "2015-03-24T12:31:33.8700000"
output c# datetime
I tried doing this
DateTime.ParseExact(x.claimDetails.clmDOA, "yyyy-MM-dd HHmmss", CultureInfo.InvariantCulture)
Buit it gave exception
String was not recognized as a valid DateTime
Please Note: I googled thoroghly . Somehow i couldnt find any string
with "T" included as in datetime string.
Prior to downvoting if one can suggest me exactly where a question is answered with datetime string containg a T in it or of this format.yyyy-MM-dd'T'hh:mm:ss.fffffff
DateTime dt = DateTime.Parse(example);
DateTime dt = DateTime.ParseExact(example, "yyyy-MM-dd'T'hh:mm:ss.fffffff", CultureInfo.InvariantCulture);
Should work for you.
From DateTime.ParseExact documentation;
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 are not.
You need to use T as a string literal delimiter, specify : as a TimeSeparator and seconds fraction (with fffffff specifier) as well.
var dt = DateTime.ParseExact("2015-03-24T12:31:33.8700000",
"yyyy-MM-dd'T'HH:mm:ss.fffffff",
CultureInfo.InvariantCulture);
DateTime.ParseExact(example , "yyyy MM dd HH:mm:ss", CultureInfo.InvariantCulture);

how to display only date from DateTime [duplicate]

Display only date and no time

i m getting date from sql server database and it is displaying datetime as 1/15/2015 12:00:00 AM.
code in c# i used is:
dob_lbl.Text = reader[6].ToString();
//this is extracted using Sqlconnection so it's in array format.
i need only date to display.pls help.
try this:
string strDate = reader[6].ToString();
dob_lbl.Text = DateTime.ParseExact(strDate, "M/dd/yyyy hh:mm:ss tt",
CultureInfo.InvariantCulture).ToString("yyyy/MM/dd");
The ToShortDateString method of DateTime should help with this.
Use it like:
string strDate = reader[6].ToString();
DateTime dateTime = DateTime.Parse(strDate);
string justDateStr = dateTime.ToShortDateString();
You could simply split the string and use the first part of the resulting array.
Something like:
dob_lbl.Text = reader[6].ToString().Split()[0];

how to convert date from yyyyMMdd format to mm-dd-yyyy fomrat
I have a string which contains date in yyyyMMdd format. I want to convert that date into system date format using ConvertTo.DateTime() method or any other simple method.
string value = "19851231"; //yyyyMMdd
DateTime dateTime = 1985/12/31;
string time = "19851231";
DateTime theTime= DateTime.ParseExact(time,
"yyyyMMdd",
CultureInfo.InvariantCulture,
DateTimeStyles.None);
have at look at the static methods DateTime.Parse() and DateTime.TryParse(). They will allow you to pass in your date string and a format string, and get a DateTime object in return.
