Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Shared Function Compare ( _
d1 As Decimal, _
d2 As Decimal _
) As Integer
'Usage
Dim d1 As Decimal
Dim d2 As Decimal
Dim returnValue As Integer
returnValue = Decimal.Compare(d1, d2)
public static int Compare (
decimal d1,
decimal d2
)
public:
static int Compare (
Decimal d1,
Decimal d2
)
public static int Compare (
Decimal d1,
Decimal d2
)
public static function Compare (
d1 : decimal,
d2 : decimal
) : int
Parameter
- d1
Ein Decimal.
- d2
Ein Decimal.
Rückgabewert
Eine Zahl mit Vorzeichen, die das Verhältnis zwischen den Werten von d1 und d2 angibt.
Rückgabewert |
Bedeutung |
|---|---|
Kleiner als 0 (null) |
d1 ist kleiner als d2. |
0 (null) |
d1 und d2 sind gleich. |
Größer als 0 (null) |
d1 ist größer als d2. |
Beispiel
Im folgenden Codebeispiel werden mehrere Decimal-Werte mithilfe der Compare-Methode mit einem Decimal-Referenzwert verglichen.
