Assembly:  mscorlib (in mscorlib.dll)

public override int GetDayOfYear(
	DateTime time
)

Parameters

time
Type: System.DateTime

The date value to read. The UmAlQuraCalendar class supports only dates from 04/30/1900 00.00.00 (Gregorian date) through 11/16/2077 23:59:59 (Gregorian date).

Return Value

An integer from 1 through 355 that represents the day of the year specified by the time parameter.

Exception Condition
ArgumentOutOfRangeException

time is outside the range supported by this calendar.

The day of the year is defined as the number of days from the first day of the year. For example, the GetDayOfYear method returns 1 for the first day of the first month of the year, and the total number of days in the year for the last day of the last month.

The following example displays the values of several components of a DateTime in terms of the Um Al Qura calendar.

using System.Globalization;

public class Example
{
   public static void Main()
   {
      DateTime date1 = new DateTime(2011, 4, 3, new GregorianCalendar());
      Calendar cal = new UmAlQuraCalendar();

      Console.WriteLine("{0:MMMM d, yyyy} in the Gregorian calendar is equivalent to:", date1);
      DisplayCalendarInfo(cal, date1);

      // Add 2 years and 10 months by calling UmAlQuraCalendar methods.
      date1 = cal.AddYears(date1, 2);
      date1 = cal.AddMonths(date1, 10);       

      Console.WriteLine("After adding 2 years and 10 months in the {0} calendar,", 
                        GetCalendarName(cal));
      Console.WriteLine("{0:MMMM d, yyyy} in the Gregorian calendar is equivalent to:", date1);
      DisplayCalendarInfo(cal, date1);
   }

   private static void DisplayCalendarInfo(Calendar cal, DateTime date1)
   {
      Console.WriteLine("   Calendar:   {0}", GetCalendarName(cal));    
      Console.WriteLine("   Era:        {0}", cal.GetEra(date1));
      Console.WriteLine("   Year:       {0}", cal.GetYear(date1));
      Console.WriteLine("   Month:      {0}", cal.GetMonth(date1));
      Console.WriteLine("   DayOfYear:  {0}", cal.GetDayOfYear(date1));
      Console.WriteLine("   DayOfMonth: {0}", cal.GetDayOfMonth(date1));
      Console.WriteLine("   DayOfWeek:  {0}\n", cal.GetDayOfWeek(date1));
   }

   private static string GetCalendarName(Calendar cal)
   {
      return cal.ToString().Replace("System.Globalization.", "").
             Replace("Calendar", "");   
   }
}
// The example displays the following output:
//    April 3, 2011 in the Gregorian calendar is equivalent to:
//       Calendar:   UmAlQura
//       Era:        1
//       Year:       1432
//       Month:      4
//       DayOfYear:  118
//       DayOfMonth: 29
//       DayOfWeek:  Sunday
//    
//    After adding 2 years and 10 months in the UmAlQura calendar,
//    January 1, 2014 in the Gregorian calendar is equivalent to:
//       Calendar:   UmAlQura
//       Era:        1
//       Year:       1435
//       Month:      2
//       DayOfYear:  59
//       DayOfMonth: 29
//       DayOfWeek:  Wednesday
