Thank you so much
I have solved the problem
This code is for anyone who wants to use it

    public static Service_Get_Data Get_Data_D(string svrIDE)
{
    Exam_Entity _db = new Exam_Entity();
    CultureInfo arSA = new CultureInfo("ar-SA");
    arSA.DateTimeFormat.Calendar = new HijriCalendar();

    return  ((from m in _db.Svr_M
                             join d in _db.Svr_D
                             on m.svrIDE equals d.svrIDE
                             join b in _db.sch_trans on
                             d.TRN_recIdNew equals b.rec_id
                             join s in _db.Saf_List on

                             where d.svrIDE == svrIDE && s.saf_id == u.saf_id && E.EncId == 4001
                             select new

How can i convert Gregorain year to Hijri year?

You can simply pass a TemporalAccessor e.g. LocalDate, ZonedDateTime etc. to HijrahChronology.INSTANCE#date as shown below:

import java.time.LocalDate;
import java.time.Month;
import java.time.ZoneId;
import java.time.chrono.HijrahChronology;
import java.time.chrono.HijrahDate;
import java.time.temporal.TemporalAdjusters;

public class Main {
    public static void main(String[] args) {
        // Change the time-zone as per your requirement.
        ZoneId myZoneId = ZoneId.of("Etc/UTC");

        HijrahDate hijrahDate1 = HijrahChronology.INSTANCE.date(LocalDate.now(myZoneId));
        System.out.println(hijrahDate1);

        // ########Another example########

        // HijrahDate on the last day of January 1994 at the time zone of Etc/UTC
        HijrahDate hijrahDate2 = HijrahChronology
                .INSTANCE                                   // Instance of HijrahChronology
                .date(LocalDate.of(1994, Month.JANUARY, 1)  // LocalDate of 01-Jan-1994
                .with(TemporalAdjusters.lastDayOfMonth())   // On the last day of Jan-1994
                .atStartOfDay()                             // At the start of the day i.e. 00:00
                .atZone(myZoneId));                         // At the time zone of Etc/UTC
        System.out.println(hijrahDate2);
    }
}

Output:

Hijrah-umalqura AH 1441-12-27
Hijrah-umalqura AH 1414-08-19

Convert gregorian date to Hijri date

Yeartext1 , Monthtext1 and Monthtext1 are UITextField

resultlable is UILabel

    let dateFormatter = NSDateFormatter()

    dateFormatter.dateFormat = "dd-MM-yyyy"

    let GregorianDate = dateFormatter.dateFromString("\(Daytext1.text!)-\(Monthtext1.text!)-\(Yeartext1.text!)")

    let islamic = NSCalendar(identifier: NSCalendarIdentifierIslamicUmmAlQura)

    let components = islamic?.components(NSCalendarUnit(rawValue: UInt.max), fromDate: GregorianDate!)

    resultlable.text = "\(components!.year) - \(components!.month) - \(components!.day)"

It will take an Gregorian Date 5-10-2015 and it will give you the islamic date 1436 - 12 - 22

*There is a small probability of one day error
