Addiert zwei angegebene Decimal-Werte.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Shared Operator + ( _
d1 As Decimal, _
d2 As Decimal _
) As Decimal
'Usage
Dim d1 As Decimal
Dim d2 As Decimal
Dim returnValue As Decimal
returnValue = (d1 + d2)
public static decimal operator + (
decimal d1,
decimal d2
)
public:
static Decimal operator + (
Decimal d1,
Decimal d2
)
J# unterstützt keine überladenen Operatoren.
JScript unterstützt die Verwendung von überladenen Operatoren, aber nicht die Deklaration von neuen überladenen Operatoren.
Parameter
- d1
Ein Decimal.
- d2
Ein Decimal.
Rückgabewert
Das Decimal-Ergebnis der Addition von d1 und d2.
Ausnahmen
| Ausnahmetyp | Bedingung |
|---|---|
Der Rückgabewert ist kleiner als MinValue oder größer als MaxValue. |
Beispiel
Im folgenden Codebeispiel werden mehrere Paare von Decimal-Werten erstellt. Anschließend werden ihre Summen mit dem Addition-Operator berechnet.
