PerCalPlus.GregorianDateToPersian(1999, 8, 2) // "1378/05/11"
PerCalPlus.GregorianDateToPersian("5/27/2015 3:14:25 PM") // "1394/03/06"
PerCalPlus.GregorianDateToPersian(DateTime.Now) // "1394/07/16"
PerCalPlus.GregorianDateToPersianLong(DateTime.Now) // "پنجشنبه - 16 مهر - 1394"

PerCalPlus.PersianDateToGregorian(1366, 12, 2) // "2/21/1988 12:00:00 AM"
PerCalPlus.PersianDateToGregorian(1366, 12, 2, 14, 22, 15) // "2/21/1988 2:22:15 PM"
PerCalPlus.PersianDateToGregorian("1366/12/2", 
	PerCalPlus.DateStringType.ToShortDateString) // "2/21/1988 12:00:00" AM
PerCalPlus.PersianDateToGregorian("1394/07/13 08:44:28 ب.ظ", 
	PerCalPlus.DateStringType.Now) // "10/5/2015 12:00:00 AM"
PerCalPlus.PersianDateToGregorian("دوشنبه - 2 اسفند - 1366", 
	PerCalPlus.DateStringType.ToLongDateString) // "2/21/1988 12:00:00 AM"

PerCalPlus.ShortYearToLongYear(66) // "1366"
PerCalPlus.ShortYearToLongYear("66") // "1366"

Converting from Gregorian Date to Persian

There are two methods that you can use for this purpose, if you want short date, you can use one of these three overloads:

PerCalPlus.GregorianDateToPersian(1999, 8, 2) // "1378/05/11"
PerCalPlus.GregorianDateToPersian("5/27/2015 3:14:25 PM") // "1394/03/06"
PerCalPlus.GregorianDateToPersian(DateTime.Now) // "1394/07/16"

If you need long string date, you can use:

PerCalPlus.GregorianDateToPersianLong(DateTime.Now) // "پنجشنبه - 16 مهر - 1394"

Converting from Persian Date to Gregorian

There is one method for this with five overloads, two of them take int as argument:

PerCalPlus.PersianDateToGregorian(1366, 12, 2) // "2/21/1988 12:00:00 AM"
PerCalPlus.PersianDateToGregorian(1366, 12, 2, 14, 22, 15) // "2/21/1988 2:22:15 PM"

The other three take a date string, note that you should specify what kind of date string you're supplying as argument through PerCalPlus.DateStringType enumeration, these three kind of strings are the same as the one created by these three methods:

PerCalPlus.Now() // "1394/07/16 07:34:34 ب.ظ"
PerCalPlus.ToShortDateString() // "1394/07/16"
PerCalPlus.ToLongDateString() // "پنجشنبه - 16 مهر - 1394"

In the enum part of method argument, you should specify what kind of date string you want to supply as an argument, these three are PerCalPlus.DateStringType.ToShortDateString and PerCalPlus.DateStringType.Now and PerCalPlus.DateStringType.ToLongDateString which correspond to the aforementioned methods, note that the date string should conform to the format that produced previously by the PersianCalendarPlus or it isn't going to work:

PerCalPlus.PersianDateToGregorian("1366/12/2", 
	PerCalPlus.DateStringType.ToShortDateString) // "2/21/1988 12:00:00 AM"

PerCalPlus.PersianDateToGregorian("1394/07/13 08:44:28 ب.ظ", 
	PerCalPlus.DateStringType.Now) // "10/5/2015 12:00:00 AM"

PerCalPlus.PersianDateToGregorian("دوشنبه - 2 اسفند - 1366", 
	PerCalPlus.DateStringType.ToLongDateString) // "2/21/1988 12:00:00 AM"
