TimeSpan.Negate Methode
Definitie
Belangrijk
Bepaalde informatie heeft betrekking op een voorlopige productversie die aanzienlijk kan worden gewijzigd voordat deze wordt uitgebracht. Microsoft biedt geen enkele expliciete of impliciete garanties met betrekking tot de informatie die hier wordt verstrekt.
Retourneert een nieuw TimeSpan object waarvan de waarde de negatieve waarde van dit exemplaar is.
public:
TimeSpan Negate();public TimeSpan Negate();member this.Negate : unit -> TimeSpanPublic Function Negate () As TimeSpanRetouren
Een nieuw object met dezelfde numerieke waarde als dit exemplaar, maar met het tegenovergestelde teken.
Uitzonderingen
De genegeerde waarde van dit exemplaar kan niet worden vertegenwoordigd door een TimeSpan; dat wil gezegd, de waarde van dit exemplaar is TimeSpan.MinValue.
Voorbeelden
In het volgende voorbeeld wordt de Negate methode toegepast op verschillende TimeSpan objecten.
// Example of the TimeSpan.Duration( ) and TimeSpan.Negate( ) methods,
// and the TimeSpan Unary Negation and Unary Plus operators.
using System;
class DuraNegaUnaryDemo
{
const string dataFmt = "{0,22}{1,22}{2,22}" ;
static void ShowDurationNegate( TimeSpan interval )
{
// Display the TimeSpan value and the results of the
// Duration and Negate methods.
Console.WriteLine( dataFmt,
interval, interval.Duration( ), interval.Negate( ) );
}
static void 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( dataFmt,
"TimeSpan", "Duration( )", "Negate( )" );
Console.WriteLine( dataFmt,
"--------", "-----------", "---------" );
// Create TimeSpan objects and apply the Unary Negation
// and Unary Plus operators to them.
ShowDurationNegate( new TimeSpan( 1 ) );
ShowDurationNegate( new TimeSpan( -1234567 ) );
ShowDurationNegate(
+ new TimeSpan( 0, 0, 10, -20, -30 ) );
ShowDurationNegate(
+ new TimeSpan( 0, -10, 20, -30, 40 ) );
ShowDurationNegate(
- new TimeSpan( 1, 10, 20, 40, 160 ) );
ShowDurationNegate(
- new TimeSpan( -10, -20, -30, -40, -50 ) );
