TaiwanCalendar.GetDayOfYear Method

Returns the day of the year in the specified DateTime.

Namespace:  System.Globalization
Assembly:  mscorlib (in mscorlib.dll)
Public Overrides Function GetDayOfYear ( _
	time As DateTime _
) As Integer


Type: System.DateTime
The DateTime to read.

Return Value

Type: System.Int32
An integer from 1 to 366 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. The total is the same as the value returned by GetDaysInYear.

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

Imports System.Globalization

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 TaiwanCalendar.
      Dim myCal As New TaiwanCalendar()

      ' Displays the values of the DateTime.
      outputBlock.Text += String.Format("April 3, 2002 of the Gregorian calendar equals the following in the Taiwan 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
