TimeSpan.op_Subtraction-Methode
Subtrahiert eine angegebene TimeSpan von einer anderen angegebenen TimeSpan.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Shared Operator - ( _
t1 As TimeSpan, _
t2 As TimeSpan _
) As TimeSpan
'Usage
Dim t1 As TimeSpan
Dim t2 As TimeSpan
Dim returnValue As TimeSpan
returnValue = (t1 - t2)
public static TimeSpan operator - (
TimeSpan t1,
TimeSpan t2
)
public:
static TimeSpan operator - (
TimeSpan t1,
TimeSpan t2
)
J# unterstützt keine überladenen Operatoren.
JScript unterstützt die Verwendung von überladenen Operatoren, aber nicht die Deklaration von neuen überladenen Operatoren.
Parameter
- t1
Eine TimeSpan.
- t2
Eine TimeSpan.
Rückgabewert
Eine TimeSpan, deren Wert das Ergebnis von Wert von t1 minus Wert von t2 ist.
Ausnahmen
| Ausnahmetyp | Bedingung |
|---|---|
Der Rückgabewert ist kleiner als MinValue oder größer als MaxValue. |
Beispiel
Im folgenden Codebeispiel werden mehrere Paare von TimeSpan-Objekten erstellt. Anschließend werden ihre Differenzen mithilfe des Subtraction-Operators berechnet.
