Returns the day of the year in the specified DateTime.

Namespace:  System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public Overrides Function GetDayOfYear ( _
	time As DateTime _
) As Integer

Parameters

time
Type: System.DateTime
The DateTime to read.

Return Value

Type: System.Int32
An integer from 1 to 355 that represents the day of the year in the specified DateTime.

The day of the year is defined as the number of days from the first day of the year. For example, GetDayOfYear for the first day of the first month returns 1, and GetDayOfYear for the last day of the last month returns the total number of days in that year, which is the same value returned by GetDaysInYear.

The following code example displays the values of several components of a DateTime in terms of the Hijri calendar.

Public Class Example
   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      ' Sets a DateTime to April 3, 2002 of the Gregorian calendar.
      Dim myDT As New DateTime(2002, 4, 3, New GregorianCalendar())

      ' Creates an instance of the HijriCalendar.
      Dim myCal As New HijriCalendar()

      ' Displays the values of the DateTime.
      outputBlock.Text += String.Format("April 3, 2002 of the Gregorian calendar equals the following in the Hijri calendar:") & vbCrLf
      DisplayValues(outputBlock, myCal, myDT)

      ' Adds two years and ten months.
      myDT = myCal.AddYears(myDT, 2)
      myDT = myCal.AddMonths(myDT, 10)

      ' Displays the values of the DateTime.
      outputBlock.Text &= "After adding two years and ten months:" & vbCrLf
      DisplayValues(outputBlock, myCal, myDT)
   End Sub 

   Public Shared Sub DisplayValues(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal myCal As Calendar, ByVal myDT As DateTime)
      outputBlock.Text += String.Format("   Era:        {0}", myCal.GetEra(myDT)) & vbCrLf
      outputBlock.Text += String.Format("   Year:       {0}", myCal.GetYear(myDT)) & vbCrLf
      outputBlock.Text += String.Format("   Month:      {0}", myCal.GetMonth(myDT)) & vbCrLf
      outputBlock.Text += String.Format("   DayOfYear:  {0}", myCal.GetDayOfYear(myDT)) & vbCrLf
      outputBlock.Text += String.Format("   DayOfMonth: {0}", myCal.GetDayOfMonth(myDT)) & vbCrLf
      outputBlock.Text += String.Format("   DayOfWeek:  {0}", myCal.GetDayOfWeek(myDT)) & vbCrLf
      outputBlock.Text &= vbCrLf
   End Sub
End Class  
' This example produces the following output.
'    April 3, 2002 of the Gregorian calendar equals the following in the Hijri calendar:

'       Era:        1
'       Year:       1425
'       Month:      11
