How to Convert long string to DateTime?

I have a date string in the following format:
var dateString = Fri Jun 26 2020 00:00:00 GMT+0100 (British Summer Time)
How can I convert this to a DateTime in C# such as 26/06/2020 00:00:00
I have tried:
DateTime.Parse(dateString);
And:
DateTime.ParseExact(dateString);
And I get:
System.FormatException: 'String was not recognized as a valid DateTime.'

You can accomplish this by using DateTime.ParseExact and providing a custom date time format. However, this will only work if you first modify the input string to be able to fit the custom date and time format strings that are included in .net.
CultureInfo provider = CultureInfo.InvariantCulture;
var input = "Fri Jun 26 2020 00:00:00 GMT+0100 (British Summer Time)";
// set up a regex that will match the text starting with GMT, and extract just the timezone offset
// (the description of the timezone is irrelevant here)
var r = new Regex(#"GMT([+-]\d\d\d\d) \([\w\s]*\)");
// this will remove the extra text: "Fri Jun 26 2020 00:00:00 +0100"
// now we can match it in our format string
var s = r.Replace(input, "$1");
var f = "ddd MMM dd yyyy hh:mm:ss zzz"; // matches the s variable
var d = DateTime.ParseExact(s, f, provider); // you now have parsed your date
This will include the timezone offset in the DateTime object. If you just want it to be set to "26/06/2020 00:00:00" and to ignore the datetime offset, then just change the regex replace above to replace with String.Empty instead of $1.

This will solve your problem.
var dateString = "Fri Jun 26 2020 00:00:00 GMT + 0100(British Summer Time)"; Console.WriteLine(DateTime.Parse(dateString.Substring(4, 11)));

Hello so what you can do is you can take advantage of "datetime" class and just write this:
DateTime.Now.ToString("MM/dd/yyyy HH:mm");

On converting a string to a DateTime object

Am unable to convert a string which represents date and time ex: "Tue Mar 18 14:37:34 PDT 2014" to a DateTime object. From the format I can figure it out to be in the RFC 1123 format. What is the best way to parse date strings as above?

Timezone literals are not supported by DateTime.Parse/ParseExact. Here is a workaround:
string inputDate = "Tue Mar 18 14:37:34 PDT 2014";
inputDate = inputDate.Replace("PDT", "-7");
DateTime d = DateTime.ParseExact(inputDate, "ddd MMM dd HH:mm:ss z yyyy", culture);
Console.WriteLine(d);

If you can make the format of the string like this (you are pretty close):
Sat, 01 Nov 2008 19:35:00 GMT
You can use DateTime.Parse(dateString);

DateTime format in c# .Net

I have a json, I parse the json and get a value in a var created_on like this:
var created_on = jsonr["created_at"];
The value is
created_on = Tue Feb 04 14:02:45 +0000 2014
i want to convert it to utc.
I followed quick links in stack but am not able to format accordingly.
Anyone who knows this?

You can use ParseExact to parse the string into a date:
DateTime.ParseExact(created_on,
"ddd MMM dd HH:mm:ss zz00 yyyy",
CultureInfo.InvariantCulture)
.ToUniversalTime();

JSON date from tweeter to C# format

How to format a JSON date obtained from twitter to a C# DateTime ?
Here is the format of the date I receive :
"Tue, 19 Feb 2013 13:06:17 +0000"
Can I do it with JSON.NET ?

Solved with use of DateTime.ParseExact
-> http://blog.kevinyu.org/2012/07/handling-json-in-net.html
Link Update: the linked blog post is offline. It cached copy can still be referenced via the Way Back Machine Internet Archive.
The common .NET code copied from the blog post is:
public const string Const_TwitterDateTemplate = "ddd MMM dd HH:mm:ss +ffff yyyy";
DateTime createdAt = DateTime.ParseExact((string)jo["created_at"],
Const_TwitterDateTemplate, new System.Globalization.CultureInfo("en-US"));
where
variable jo is a JSON object representing the created_at date property, but effectively the Twitter date string goes into this parameter

Part of code from flow's answer.
public const string Const_TwitterDateTemplate = "ddd MMM dd HH:mm:ss +ffff yyyy";
DateTime createdAt = DateTime.ParseExact((string)jo["created_at"], Const_TwitterDateTemplate, new System.Globalization.CultureInfo("en-US"));

The answers above that use the ffff format specifier seem to return the correct result, but technically this is wrong. ffff is the format specifier for ten thousandths of a second, and the +0000 in a Twitter date indicates the hours and minutes offset from UTC. See the format below:
string twitterTime = "Wed Feb 22 15:49:01 +0000 2017";
string twitterTimeformat = "ddd MMM dd HH:mm:ss zzz yyyy";
DateTime dateTime = DateTime.ParseExact(twitterTime, twitterTimeformat,
CultureInfo.InvariantCulture, DateTimeStyles.AdjustToUniversal);
Console.WriteLine(dateTime);
Result: 2/22/2017 3:49:01 PM
You can edit the DateTimeStyles enumeration to return the local time instead of UTC if desired.
Custom Date and Time Format Strings

It's DateTimeOffset not DateTime. Following should work.
DateTimeOffset parsed = DateTimeOffset.Parse("Tue, 19 Feb 2013 13:06:17 +0000");

I needed a PowerShell variant of these answers and the following worked for me.
PS> $Created_At = 'Fri Jun 05 18:15:48 +0000 2020'
PS> [datetime]::ParseExact($Created_At,'ddd MMM dd HH:mm:ss zzz yyyy',(Get-Culture))

Casting String to DateTime

I have a string in format
Jul 13 2011 1:07PM
I want to cast it as
dd/MM/yyyy HH:mm tt
e.g: 13/7/2011 11:49:00 AM //string=Jul 13 2011 1:07PM
I am using following code to cast it to date.
DateTime date = Convert.ToDateTime(Convert.ToDateTime(myDateString).ToString("dd/MM/yyyy HH:mm:ss"));
This works fine if my day in my string is less than 13
Jul 12 2011 1:07PM //this will cast to desire format fine!
Jul 13 2011 1:07PM //gives error String was not recognized as a valid DateTime.
I understand that it is taking day as month but I can not found a way to cast it to desire format.

See DateTime.ParseExact :
DateTime date = DateTime.ParseExact(myDateString, "MMM dd YYYY H:mmtt", CultureInfo.InvariantCulture);
See also Time Format Strings

You should use DateTime.TryParse
DateTime dt ;
if (DateTime.TryParse("Jul 13 2011 1:07PM",out dt))
MessageBox.Show("Converted to Date object");
Post that you use the ToString() method to get the desired output
dt.ToString("dd/MM/yyyy HH:mm")

First, convert the string Jul 13 2011 1:07PM to a date:
var date = Convert.ToDateTime("Jul 13 2011 1:07PM");
Then, convert it to a string in the format you like:
var dateText = date.ToString("dd/MM/yyyy HH:mm:ss");

I believe you're searching for this:
Date.ParseExact("Jul 13 2011 1:07PM", "MMM d yyyy h:mmtt", Globalization.CultureInfo.InvariantCulture)
