public:
static bool operator <(TimeSpan t1, TimeSpan t2);public static bool operator < (TimeSpan t1, TimeSpan t2);static member ( < ) : TimeSpan * TimeSpan -> boolPublic Shared Operator < (t1 As TimeSpan, t2 As TimeSpan) As BooleanParamètres
- t1
- TimeSpan
Premier intervalle de temps à comparer.
- t2
- TimeSpan
Second intervalle de temps à comparer.
Retours
true si la valeur de t1 est inférieure à celle de t2 ; sinon, false.
