Important

Certaines informations portent sur la préversion du produit qui est susceptible d’être en grande partie modifiée avant sa publication. Microsoft exclut toute garantie, expresse ou implicite, concernant les informations fournies ici.

Indique si un TimeSpan spécifié est inférieur ou égal à un autre TimeSpan spécifié.

public:
 static bool operator <=(TimeSpan t1, TimeSpan t2);

public static bool operator <= (TimeSpan t1, TimeSpan t2);

static member ( <= ) : TimeSpan * TimeSpan -> bool

Public Shared Operator <= (t1 As TimeSpan, t2 As TimeSpan) As Boolean

Paramètres

t1: TimeSpan

Premier intervalle de temps à comparer.

t2: TimeSpan

Second intervalle de temps à comparer.

Retours

Boolean

true si la valeur de t1 est inférieure ou égale à celle de t2 ; sinon, false.
