Metodo TimeSpan.op_LessThanOrEqual
.NET Framework 2.0
Indica se un TimeSpan specificato è minore o uguale a un altro TimeSpan specificato.
Spazio dei nomi: System
Assembly: mscorlib (in mscorlib.dll)
Assembly: mscorlib (in mscorlib.dll)
J# non supporta operatori in overload.
JScript supporta l'utilizzo di operatori in overload ma non la dichiarazione di nuove.
Parametri
- t1
Oggetto TimeSpan.
- t2
Oggetto TimeSpan.
Valore restituito
true se il valore di t1 è minore o uguale al valore di t2; in caso contrario, false.Nell'esempio di codice riportato di seguito vengono confrontati diversi oggetti TimeSpan a un oggetto TimeSpan di riferimento mediante l'operatore LessThanOrEqual.
