Calendar::AddMilliseconds Method

Returns a DateTime that is the specified number of milliseconds away from the specified DateTime.

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

public:
virtual DateTime AddMilliseconds(
	DateTime time, 
	double milliseconds
)

Parameters

time
Type: System::DateTime
The DateTime to add milliseconds to.
milliseconds
Type: System::Double
The number of milliseconds to add.

Return Value

Type: System::DateTime
The DateTime that results from adding the specified number of milliseconds to the specified DateTime.

ExceptionCondition
ArgumentException

The resulting DateTime is outside the supported range of this calendar.

ArgumentOutOfRangeException

milliseconds is outside the supported range of the DateTime return value.

The milliseconds value is rounded to the nearest integer before it is added to the specified DateTime. If milliseconds is negative, the resulting DateTime is earlier than the specified DateTime.

The day part of the resulting DateTime is affected if the resulting time is outside the day of the specified DateTime. The month part of the resulting DateTime is affected if the resulting day is outside the month of the specified DateTime. The year part of the resulting DateTime is affected if the resulting month is outside the year of the specified DateTime. The era part of the resulting DateTime is affected if the resulting year is outside the era of the specified DateTime.

The Kind property of the returned DateTime value always equals DateTimeKind::Unspecified. You can preserve the Kind property of the time parameter by calling the DateTime::SpecifyKind method, as the following example shows.

No code example is currently available or this language may not be supported.

The following code 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 );
}
