C# Convert string to date time '2017-08-18 06:00:00 IST' to 'Fri 28th Jul 2017 / 06:00:00 IST'

Question

I have DateTime format string '2017-08-18 06:00:00 IST' i want to convert to 'Fri 18th Aug 2017 / 06:00:00 IST'

please help me in this.

Thanks in advance.

Aside from anything else, it's unclear whether you're really starting with a string or a `DateTime`. A [mcve] would have helped here, along with how far you've already got. — Jon Skeet, Oct 08 '17 at 07:23

Converting a `DateTime` to `String`

I'm not clear exactly on if you are intending to do string --> DateTime --> string... But the following solution will do the DateTime to string, and gets you the desired output:

// set a date in UTC format
DateTime dateUtc = new DateTime(2017, 08, 18, 06, 00, 00).ToUniversalTime();

// convert the UTC date to the IST time zone
DateTime dateIST = TimeZoneInfo.ConvertTimeBySystemTimeZoneId(dateUtc, "UTC", "India Standard Time");
string timeZoneText = "IST";

// the string you want
string result = String.Format("{0:ddd d}{1} {0:MMM yyyy / HH:mm:ss} {2}", dateIST,
    (DateTime.Now.Day % 10 == 1 && DateTime.Now.Day != 11) ? "st"
    : (DateTime.Now.Day % 10 == 2 && DateTime.Now.Day != 12) ? "nd"
    : (DateTime.Now.Day % 10 == 3 && DateTime.Now.Day != 13) ? "rd"
    : "th", timeZoneText);

The key here is the string format

{0:ddd d}{1} {0:MMM yyyy / HH:mm:ss} {2}

// 0 = DateTime (converted to your time zone, ex: IST)
// 1 = the "1st", "2nd", "3rd", "#th"
// 2 = "IST"

This will result in: Fri 18th Aug 2017 / 06:00:00 IST

This will only work with IST zone specifically, right? – Igor Soloydenko Oct 08 '17 at 07:21
@IgorSoloydenko no- it's generic – Svek Oct 08 '17 at 07:22
IST is "Indian Standard Time", it's _not_ "first". Therefore, your code is not generic, sorry – Igor Soloydenko Oct 08 '17 at 07:24
@IgorSoloydenko what do you mean by "first"? – Svek Oct 08 '17 at 07:35
@IgorSoloydenko did you try the code? I'm not sure you understood what it accomplished – Svek Oct 08 '17 at 07:39
Your code will not work with strings that have arbitrary timezone suffixes. – Igor Soloydenko Oct 08 '17 at 07:40
@IgorSoloydenko - you could put any suffix by editing the string, and what did you mean with "first"? – Svek Oct 08 '17 at 07:42
but how will i convert '2017-08-18 06:00:00 IST' to DateTime – Harshal Bhagat Oct 08 '17 at 07:43
@HarshalBhagat -- I thought that the OP meant how to create a **string format** from a `DateTime`. Not `string` to `string`. – Svek Oct 08 '17 at 07:46
@HarshalBhagat there's no easy way to achieve what you want without using external libraries. (In case your input will have various timezone suffixes): https://stackoverflow.com/a/241885/482868 – Igor Soloydenko Oct 08 '17 at 07:46
@Svek do you realize Harshal Bhagat **IS** the OP?! – Igor Soloydenko Oct 08 '17 at 07:48
@IgorSoloydenko -- I just noticed that, but why did he accept this answer then? I'm confused... Haha... I think I'll move on to something else... Please downvote if you want me to delete this – Svek Oct 08 '17 at 07:50
