I found the answers to my questions

  PersianCalendar pc = new PersianCalendar();
            var Birthdate =  pc.GetYear(DateTime.Parse(viewmodel.BirthDateDay));
            var DateNow = pc.GetYear(DateTime.Now);                
            var resault = ((Convert.ToInt32(DateNow) - Convert.ToInt32(Birthdate))   " "   "سال");

You can use PersianCalendar in .NET like code below then minus date2 from date1 which gives you a TimeSpan object (time between two dates).

        PersianCalendar pc = new PersianCalendar();
        DateTime dt1 = new DateTime(1399, 01, 01, pc);
        DateTime dt2 = new DateTime(1400, 01, 01, pc);
        TimeSpan timeBetween = dt2 - dt1;
        Console.WriteLine(timeBetween);
