.NET How to parse a Persian / Farsi date string (Jalali calendar) into a DateTime object?

Question

I\'ve run across several great code libraries for converting a Persian (Jalali calendar) date to a Gregorian date. However, my original source is a string, not a DateTime ob

Answer 1

For parsing the date string, I simply use the default calendar to get the date values (year, month, day, etc.)

I then use this library here to convert the Persian date values to the Gregorian date values.

My code now looks like this:

string persianDate = "1390/02/07";
CultureInfo persianCulture = new CultureInfo("fa-IR");
DateTime persianDateTime = DateTime.ParseExact(persianDate, "yyyy/MM/dd", persianCulture);    // this parses the date as if it were Gregorian

JalaliCalendar jc = new JalaliCalendar();
// convert the Persian calendar date to Gregorian
DateTime gregorianDateTime = jc.ToDateTime(persianDateTime.Year, persianDateTime.Month, persianDateTime.Day, persianDateTime.Hour, persianDateTime.Minute, persianDateTime.Second, persianDateTime.Millisecond);

Of course, I'll have to take care of date components with names (months, days of the week) myself, but I can deal with that pretty easily.
