TimeSpan.Duration Method

Definition

Restituisce un nuovo oggetto TimeSpan il cui valore è il valore assoluto dell'oggetto TimeSpan corrente.Returns a new TimeSpan object whose value is the absolute value of the current TimeSpan object.

``````public:
TimeSpan Duration();``````
``public TimeSpan Duration ();``
``member this.Duration : unit -> TimeSpan``
``Public Function Duration () As TimeSpan``

Returns

TimeSpan

Nuovo oggetto il cui valore è il valore assoluto dell'oggetto TimeSpan corrente.A new object whose value is the absolute value of the current TimeSpan object.

Exceptions

Il valore di questa istanza è MinValue.The value of this instance is MinValue.

Examples

Nell'esempio seguente viene applicato il metodo Duration a diversi TimeSpan oggetti.The following example applies the Duration method to several TimeSpan objects.

``````// 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
