I am trying to convert Time string to DateTime but can't.
Example: Time: 12:05:45.458 with milliseconds need to convert to time.
Any solution?

DateTime.ParseExact should solve this
DateTime result = DateTime.ParseExact("12:05:45.458", "HH:mm:ss.fff", CultureInfo.InvariantCulture);

The DateTime.ParseExtract will parse the given time and convert to DateTime object with date as current date.
var dateTime = DateTime.ParseExact("12:05:45.458", "HH:mm:ss.fff", System.Globalization.CultureInfo.InvariantCulture);
Console.WriteLine(dateTime);

You are looking for a Timespan.Parse() here. Since you do not have any date component, it is not possible to unambiguously convert to a DateTime instance.

Simple solution:
string time = "12:05:45.458";
DateTime dateTime = DateTime.ParseExact(time, "HH:mm:ss.fff",
CultureInfo.InvariantCulture);

I have a date format as shown below 2021-02-11T13:00:00+04:00 which i need to get in following format 11-FEB-20 01.00.00.000000000 PM.How can i achieve it ?
Parse and then format according to Custom date and time format strings
DateTime dt = DateTime.Parse("2021-02-11T13:00:00+04:00");
Console.WriteLine(dt.ToString("dd-MMM-yy"));
You can Parse form existing format into DateTime and then format it into String with the desired format string:
string source = "2021-02-11T13:00:00+04:00";
string result = DateTime
.Parse(source)
.ToString("dd-MMM-yy hh.mm.ss.fffffff'00' tt", CultureInfo.InvariantCulture)
.ToUpper();
Please, note
ToUpper() since we want FEB, not Feb.
fffffff'00' - we can't provide 9, but 7 digits after the decimal point, so we have to append two zeros.

I am getting GMT DateTime as string input. For example
SampleDate = "20170221T085258.732 GMT"
Now, I want to convert this to datetime object. What is the best way of doing this conversion?
You just need to use ToLocalTime() Then you can change it to whatever timezone you care about.
DateTimeOffset.Parse(SampleDate).ToLocalTime();
var offset = new Date().getTimezoneOffset();
To remove the GMT and time zone, change the following line:
document.write(d.toString().replace(/GMT.*/g,""));
Hi try this code using DateTime.ParseExact()
string SampleDate=""20170221T085258.732 GMT";
DateTime dateObject = DateTime.ParseExact(SampleDate,"ddd MMM dd yyyy HH:mm:ss 'GMT'zzz", System.Globalization.CultureInfo.InvariantCulture);
For more info heres the link for DateTime.ParseExact MSDN: https://msdn.microsoft.com/en-us/library/w2sa9yss(v=vs.110).aspx
Below code worked for me. Date contain some unwanted characters like "T",".","GMT" , once I removed those, it started working..
But I feel that, there has to be some better solution for this.
//I can write a regular expression to keep only numeric values and avoid this replacements...
SampleDate = "20170221T085258.732 GMT"
SampleDate = SampleDate.Replace("GMT", "")
SampleDate = SampleDate.Replace("T", "")
SampleDate = SampleDate.Replace(".", "")
Dim dateObject As DateTime = DateTime.ParseExact(SampleDate.Trim(), "yyyyMMddHHmmssfff", System.Globalization.CultureInfo.InvariantCulture)

I have a string like below
1/1/1970 12:00:00 AM
I want it in the yyyy-MM-dd format (in this case 1970-01-01)
My parsing code is
var actualDate = DateTime.ParseExact(actualValue,"MM/dd/yyyy HH:mm:ss tt",CultureInfo.InvariantCulture).ToString("yyyy-MM-dd");
But I keep getting the error, that the string is not recognized as a valid date time.
I looked at my variable actualValue and it is of type DateTime, so am thinking that the problem is with the format MM/dd/yyyy HH:mm:ss tt ,What is wrong with this?
First, you shouldn't be storing or fetching dates as text in the DB.
To your specific issue, however, MM and dd are the two-digit variety of month and day. Obviously your date text doesn't use the two-digit-only variety, so use M and d. Also, HH is on a 24-hour clock. Using tt, which is AM/PM, would imply not having a 24 hour clock, so you would want to use hh instead.
For more, look at MSDN for custom date/time formatting.

I got a DateTime in a string format :
"05/30/2014 12:00:00"
I want to create a DateTime object from this string by doing this :
DateTime startDate = DateTime.Parse(startDate);
However, I've got an error which says that this method has some invalid argument :
Error 1 - The best overloaded method match for 'System.DateTime.Parse(string)' has some invalid arguments
When I'm reading the doc, a string argument is definitely a good argument. What's wrong with what I'm doing?
Use DateTime.ParseExact and pass the format you have in date string. The current culture might have date form in which day comes before month like dd/mm/yy.
You are passing the same variable to ParseExact method that you have declared for DateTime. Change the name of DateTime object.
DateTime dtStartDate = DateTime.ParseExact(startDate, "MM/dd/yyyy HH:mm:ss", CultureInfo.InvariantCulture);
You can read the article from Custom Date and Time Format Strings to get more understanding for declaring the format for parsing the date string.
DateTime startDate = DateTime.ParseExact(strDate, "G", CultureInfo.InvariantCulture);
You can find more info on this here.
It looks like you are passing in your variable to parse before you have initialised it.
So you could have:
DateTime startDate = DateTime.Parse("05/30/2014 12:00:00");
Console.WriteLine(startDate);
Or, you could have:
String dateToParse = "05/30/2014 12:00:00";
DateTime startDate = DateTime.Parse(dateToParse);
Console.WriteLine(startDate);
Store your date inside a string variable and then use following:
DateTime.Parse(STRINGVARIABLE);
//Which means following
//DateTime.Parse("05/30/2014 12:00:00");
In your code, you are trying apply the format to the variable of type DateTime. Or if you want to apply the format directly to DateTime variable then you can simply write following:
DateTime.Parse("05/30/2014 12:00:00").ToString("dd MMM yyyy");

How to convert this?
public DateTime Date { get; set; }
I need to display only date.
Please could any one help to convert this to Date only
By 'display' I assume you mean to the console. Based on this assumption:
Console.WriteLine(Date.Date);
or
Console.WriteLine(Date.ToString("MM/dd/yyyy")); (as an example; there are many other strings you can pass into this overload).
More on the available strings here:
http://msdn.microsoft.com/en-us/library/8kb3ddd4(v=vs.110).aspx
I need to display only date.
The DateTime structure has numerous ways to accomplish this, most commonly .ToShortDateString() and .ToLongDateString():
var displayDate = Date.ToShortDateString();
For further customizations, you can supply a formatting string to the .ToString() method.
You can use the DateTime format string
eg,
Console.WriteLine(Date.ToShortDateString());
Console.WriteLine(Date.ToString("d"));
Console.WriteLine(Date.ToString("yyyy/MM/dd"));
See,
DateTime Format Methods - http://msdn.microsoft.com/enus/library/system.datetime_methods(v=vs.110).aspx

Custom DateTime Format Strings -
http://msdn.microsoft.com/en-us/library/8kb3ddd4(v=vs.110).aspx
A DateTime always contains the Date and the Time - but you can just output the Datepart of it by using .ToString("d") as mentioned here: Extract the date part from datetime
This will get the date with the time being 00:00:00
public DateTime date { get { return this.date; } set; }
but as stated in a previous answer to display a datetime with only the date you should check out datetime.tostring formats.
