Exempel

I följande exempel visas hur resultatet av GetWeekOfYear metoden varierar beroende på vilka FirstDayOfWeek värden och CalendarWeekRule värden som används. Om det angivna datumet är den sista dagen på året GetWeekOfYear returnerar det totala antalet veckor det året.

using System;
using System.Globalization;

public class SamplesCalendar  {

   public static void Main()  {

      // Gets the Calendar instance associated with a CultureInfo.
      CultureInfo myCI = new CultureInfo("en-US");
      Calendar myCal = myCI.Calendar;

      // Gets the DTFI properties required by GetWeekOfYear.
      CalendarWeekRule myCWR = myCI.DateTimeFormat.CalendarWeekRule;
      DayOfWeek myFirstDOW = myCI.DateTimeFormat.FirstDayOfWeek;

      // Displays the number of the current week relative to the beginning of the year.
      Console.WriteLine( "The CalendarWeekRule used for the en-US culture is {0}.", myCWR );
      Console.WriteLine( "The FirstDayOfWeek used for the en-US culture is {0}.", myFirstDOW );
      Console.WriteLine( "Therefore, the current week is Week {0} of the current year.", myCal.GetWeekOfYear( DateTime.Now, myCWR, myFirstDOW ));

      // Displays the total number of weeks in the current year.
      DateTime LastDay = new System.DateTime( DateTime.Now.Year, 12, 31 );
      Console.WriteLine( "There are {0} weeks in the current year ({1}).", myCal.GetWeekOfYear( LastDay, myCWR, myFirstDOW ), LastDay.Year );
   }
}

/*
This code produces the following output.  Results vary depending on the system date.

The CalendarWeekRule used for the en-US culture is FirstDay.
The FirstDayOfWeek used for the en-US culture is Sunday.
Therefore, the current week is Week 1 of the current year.
There are 53 weeks in the current year (2001).

Den här metoden kan användas för att fastställa antalet veckor under året genom att ange parametern time till den sista dagen på året.

CultureInfo.DateTimeFormat innehåller kulturspecifika värden som kan användas för parametrarna rule och firstDayOfWeek .

Egenskapen FirstDayOfWeek för CultureInfo.DateTimeFormat innehåller standardvärdet DayOfWeek som representerar den första dagen i veckan för en viss kultur med hjälp av kalendern som anges i Calendar egenskapen CultureInfo.DateTimeFormatför .

Egenskapen CalendarWeekRule för innehåller standardvärdet CalendarWeekRule som definierar en kalendervecka för en specifik kultur med hjälp av CultureInfo.DateTimeFormatCultureInfo.DateTimeFormatden kalender som anges i Calendar egenskapen för .
