Calendar Constructor ()
Initializes a new instance of the Calendar class.
Assembly: mscorlib (in mscorlib.dll)
Notes to Callers:
In the Portable Class Library, the Calendar class constructor is unavailable, and classes derived from Calendar are not public. If you want a calendar of a specific type, such as a Gregorian calendar object, you have to retrieve it from the CultureInfo::Calendar or DateTimeFormatInfo::Calendar property, or from the CultureInfo::OptionalCalendars property array.
The following example demonstrates the members of the Calendar class.
using namespace System; using namespace System::Globalization; void DisplayValues( Calendar^ myCal, DateTime myDT ) { Console::WriteLine( " Era: {0}", myCal->GetEra( myDT ) ); Console::WriteLine( " Year: {0}", myCal->GetYear( myDT ) ); Console::WriteLine( " Month: {0}", myCal->GetMonth( myDT ) ); Console::WriteLine( " DayOfYear: {0}", myCal->GetDayOfYear( myDT ) ); Console::WriteLine( " DayOfMonth: {0}", myCal->GetDayOfMonth( myDT ) ); Console::WriteLine( " DayOfWeek: {0}", myCal->GetDayOfWeek( myDT ) ); Console::WriteLine( " Hour: {0}", myCal->GetHour( myDT ) ); Console::WriteLine( " Minute: {0}", myCal->GetMinute( myDT ) ); Console::WriteLine( " Second: {0}", myCal->GetSecond( myDT ) ); Console::WriteLine( " Milliseconds: {0}", myCal->GetMilliseconds( myDT ) ); Console::WriteLine(); } int main() { // Sets a DateTime to April 3, 2002 of the Gregorian calendar. DateTime myDT = DateTime(2002,4,3,gcnew GregorianCalendar); // Uses the default calendar of the InvariantCulture. Calendar^ myCal = CultureInfo::InvariantCulture->Calendar; // Displays the values of the DateTime. Console::WriteLine( "April 3, 2002 of the Gregorian calendar:" ); DisplayValues( myCal, myDT ); // Adds 5 to every component of the DateTime. myDT = myCal->AddYears( myDT, 5 ); myDT = myCal->AddMonths( myDT, 5 ); myDT = myCal->AddWeeks( myDT, 5 ); myDT = myCal->AddDays( myDT, 5 ); myDT = myCal->AddHours( myDT, 5 ); myDT = myCal->AddMinutes( myDT, 5 ); myDT = myCal->AddSeconds( myDT, 5 ); myDT = myCal->AddMilliseconds( myDT, 5 ); // Displays the values of the DateTime. Console::WriteLine( "After adding 5 to each component of the DateTime:" ); DisplayValues( myCal, myDT ); } /* This code produces the following output. April 3, 2002 of the Gregorian calendar: Era: 1 Year: 2002 Month: 4 DayOfYear: 93 DayOfMonth: 3 DayOfWeek: Wednesday Hour: 0 Minute: 0 Second: 0 Milliseconds: 0 After adding 5 to each component of the DateTime: Era: 1 Year: 2007 Month: 10 DayOfYear: 286 DayOfMonth: 13 DayOfWeek: Saturday Hour: 5 Minute: 5 Second: 5 Milliseconds: 5 */
