How convert Gregorian date to Persian date?

I want to convert a custom Gregorian date to Persian date in C#. For example, i have a string with this contents:

string GregorianDate = "Thursday, October 24, 2013";

Now i want to have:

> string PersianDate = پنج‌شنبه 2 آبان 1392 ;

or

> string PersianDate = 1392/08/02

Thanks

Use the PersianCalendar:

string GregorianDate = "Thursday, October 24, 2013";
DateTime d = DateTime.Parse(GregorianDate);
PersianCalendar pc = new PersianCalendar();
Console.WriteLine(string.Format("{0}/{1}/{2}", pc.GetYear(d), pc.GetMonth(d), pc.GetDayOfMonth(d)));

You can use PersianDateTime:

PM> Install-Package PersianDateTime

The Reference: PersianDateTime

You can use string.Split() if you need customization.

    DateTime date = new DateTime(2013, 10, 24);
    var calendar = new PersianCalendar();
    var persianDate = new DateTime(calendar.GetYear(date), calendar.GetMonth(date), calendar.GetDayOfMonth(date));
    var result = persianDate.ToString("yyyy MMM ddd", CultureInfo.GetCultureInfo("fa-Ir"));

Adding up to other answers, You can get the first one by using PersianDateTime:

var gregorianDate = "Thursday, October 24, 2013";
var date = DateTime.Parse(gregorianDate);
var persianDate = new PersianDateTime(date);
var result = persianDate.ToString("dddd d MMMM yyyy");

The fowlling code should work in .net 4+ :

DateTime date=Convert.ToDateTime("2020-07-12T19:30:00.000Z");
string persianDateString = date.ToString("yyyy/MM/dd",new CultureInfo("fa-IR"));

persianDateString value would be:

1399/04/23

In windows 10, using framework 4+:

Console.WriteLine(Convert.ToDateTime("1392/08/02",new CultureInfo("fa-IR")));

or

Console.WriteLine(DateTime.Parse("1392/08/02", new CultureInfo("fa-IR")));

You can convert a DateTime to Iran time using this method:

DateTime timeInIran = TimeZoneInfo.ConvertTimeBySystemTimeZoneId(DateTimeToConvert, "Iran Standard Time" );
