TimeSpan.UnaryNegation(TimeSpan) Operator
Definisi
Penting
Beberapa informasi terkait produk prarilis yang dapat diubah secara signifikan sebelum dirilis. Microsoft tidak memberikan jaminan, tersirat maupun tersurat, sehubungan dengan informasi yang diberikan di sini.
Mengembalikan nilai TimeSpan yang nilainya adalah nilai yang dinegasikan dari instans yang ditentukan.
public:
static TimeSpan operator -(TimeSpan t);public static TimeSpan operator - (TimeSpan t);static member ( ~- ) : TimeSpan -> TimeSpanPublic Shared Operator - (t As TimeSpan) As TimeSpanParameter
- t
- TimeSpan
Interval waktu yang akan dinegasikan.
Mengembalikan
Objek yang memiliki nilai numerik yang sama dengan instans ini, tetapi tanda sebaliknya.
Pengecualian
Nilai yang dinegasikan dari instans ini tidak dapat diwakili oleh TimeSpan; yaitu, nilai instans ini adalah TimeSpan.MinValue.
Contoh
Contoh berikut menerapkan operator ke UnaryNegation beberapa TimeSpan objek.
// 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(1,10,20,40,160) );
