Compare deux valeurs TimeSpan et retourne un entier qui indique si la première valeur est plus courte, identique ou plus longue que la deuxième valeur.

public:
 static int Compare(TimeSpan t1, TimeSpan t2);
public static int Compare (TimeSpan t1, TimeSpan t2);
static member Compare : TimeSpan * TimeSpan -> int
Public Shared Function Compare (t1 As TimeSpan, t2 As TimeSpan) As Integer

Paramètres

t1
TimeSpan

Premier intervalle de temps à comparer.

t2
TimeSpan

Second intervalle de temps à comparer.

Retours

Int32

Une des valeurs suivantes.

Valeur Description
-1 t1 est plus court que t2.
0 t1 est égal à t2.
1 t1 est plus long que t2.

Exemples

L’exemple suivant utilise la Compare méthode pour comparer plusieurs TimeSpan objets avec un TimeSpan objet dont la valeur est un intervalle de 2 heures.

// Define a time interval equal to two hours.
TimeSpan baseInterval = new TimeSpan( 2, 0, 0);

// Define an array of time intervals to compare with
// the base interval.
TimeSpan[] spans = { 
    TimeSpan.FromSeconds(-2.5),
    TimeSpan.FromMinutes(20),
    TimeSpan.FromHours(1), 
    TimeSpan.FromMinutes(90),
    baseInterval,  
    TimeSpan.FromDays(.5), 
    TimeSpan.FromDays(1) 
};

// Compare the time intervals.
foreach (var span in spans) {
   int result = TimeSpan.Compare(baseInterval, span);
   Console.WriteLine("{0} {1} {2} (Compare returns {3})", 
                     baseInterval,
                     result == 1 ? ">" : result == 0 ? "=" : "<",
                     span, result);     
}

// The example displays the following output:
//       02:00:00 > -00:00:02.5000000 (Compare returns 1)
//       02:00:00 > 00:20:00 (Compare returns 1)
//       02:00:00 > 01:00:00 (Compare returns 1)
//       02:00:00 > 01:30:00 (Compare returns 1)
//       02:00:00 = 02:00:00 (Compare returns 0)
//       02:00:00 < 12:00:00 (Compare returns -1)
//       02:00:00 < 1.00:00:00 (Compare returns -1)
