Parsing format to DateTime

I want to format a DateTime to the following format yyyy-MM-ddTHH:mm:ssZ but keeping it in DateTime.

This is what I tried:

string t = Convert.ToString(DateTime.UtcNow);
DateTime d2 = DateTime.ParseExact(t, "yyyy-MM-ddTHH:mm:ssZ", CultureInfo.InvariantCulture);

But I am getting the following error :

System.FormatException: 'The string was not recognized as a valid DateTime value.'

this is the result where I want to get: 2018-09-05T09:29:56Z

How can I solve this problem?

DateTime is just a primitive type, and you rather convert it to the format you want.

The format is just a presentation of your DateTime type

string t = Convert.ToString(DateTime.UtcNow); // it gives you a string like 9/5/2018 9:38:40 AM
DateTime d2 = DateTime.ParseExact(t, "yyyy-MM-ddTHH:mm:ssZ", CultureInfo.InvariantCulture);

Obliviously, the format you put doesn't correspond with the string t

Try this

//to have the right format
var t = DateTime.Now.ToString("yyyy-MM-ddTHH:mm:ssZ"); //it gives 2018-09-05T09:44:14Z

//to convert a string with a format given
DateTime.ParseExact("2018-09-09:38:40Z", "yyyy-MM-ddTHH:mm:ssZ", CultureInfo.InvariantCulture)

No you cannot do that, If your requirement is to display the Date object in localized format, then you can make use of the Overrided .ToString() method like the following:

string formatString = "yyyy-MM-ddTHH:mm:ssZ";
DateTime utcDate = DateTime.UtcNow;
string formatedDate = utcDate.ToString(formatString)
