TimeSpan.UnaryNegation(TimeSpan) TimeSpan.UnaryNegation(TimeSpan) TimeSpan.UnaryNegation(TimeSpan) TimeSpan.UnaryNegation(TimeSpan) Operator

Définition

Retourne un TimeSpan dont la valeur correspond à la valeur inversée de l'instance spécifiée.Returns a TimeSpan whose value is the negated value of the specified instance.

public:
 static TimeSpan operator -(TimeSpan t);
public static TimeSpan operator - (TimeSpan t);
static member ( ~- ) : TimeSpan -> TimeSpan
Public Shared Operator - (t As TimeSpan) As TimeSpan

Paramètres

t
TimeSpan TimeSpan TimeSpan TimeSpan

Intervalle de temps à inverser.The time interval to be negated.

Retours

Objet ayant la même valeur numérique que cette instance, mais de signe contraire.An object that has the same numeric value as this instance, but the opposite sign.

Exceptions

La valeur inversée de cette instance ne peut pas être représentée par un TimeSpan ; en d’autres termes, la valeur de cette instance est MinValue.The negated value of this instance cannot be represented by a TimeSpan; that is, the value of this instance is MinValue.

Exemples

L’exemple suivant applique l' UnaryNegation opérateur à plusieurs TimeSpan objets.The following example applies the UnaryNegation operator 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
   // 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) );
