Microsoft Silverlight will reach end of support after October 2021. Learn more.
Returns the day of the year in the specified DateTime.
Namespace: System.Globalization
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Overrides Function GetDayOfYear ( _
time As DateTime _
) As Integer
public override int GetDayOfYear(
DateTime time
)
Parameters
- time
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.
Remarks
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.
Examples
The following code example displays the values of several components of a DateTime in terms of the Taiwan calendar.
