Nuovo oggetto il cui valore è il valore assoluto dell'oggetto TimeSpan corrente.
Eccezioni
Il valore di questa istanza è TimeSpan.MinValue.
Esempio
Nell'esempio seguente viene applicato il Duration metodo a diversi TimeSpan oggetti .
// Example of the TimeSpan::Duration( ) and TimeSpan::Negate( ) methods,
// and the TimeSpan Unary Negation and Unary Plus operators.
using namespace System;
const __wchar_t * protoFmt = L"{0,22}{1,22}{2,22}";
void ShowDurationNegate( TimeSpan interval )
{
// Display the TimeSpan value and the results of the
// Duration and Negate methods.
Console::WriteLine( gcnew String( protoFmt ), interval, interval.Duration(), interval.Negate() );
}
int main()
{
Console::WriteLine( "This example of TimeSpan::Duration( ), "
"TimeSpan::Negate( ), \nand the TimeSpan Unary "
"Negation and Unary Plus operators \n"
"generates the following output.\n" );
Console::WriteLine( gcnew String( protoFmt ), "TimeSpan", "Duration( )", "Negate( )" );
Console::WriteLine( gcnew String( protoFmt ), "--------", "-----------", "---------" );
// Create TimeSpan objects and apply the Unary Negation
// and Unary Plus operators to them.
ShowDurationNegate( TimeSpan(1) );
ShowDurationNegate( TimeSpan( -1234567) );
ShowDurationNegate( +TimeSpan(0,0,10,-20,-30) );
ShowDurationNegate( +TimeSpan(0,-10,20,-30,40) );
ShowDurationNegate( -TimeSpan(1,10,20,40,160) );
ShowDurationNegate( -TimeSpan( -10,-20,-30,-40,-50) );
