Surcharges
CompareTo(Object) |
Compare cette instance à un objet spécifié et retourne un entier qui indique si cette instance est plus courte, de même longueur ou plus longue que l'objet spécifié. |
CompareTo(TimeSpan) |
Compare cette instance à un objet TimeSpan spécifié et retourne un entier qui indique si cette instance est plus courte, identique ou plus longue que l'objet TimeSpan. |
Remarques
Les deux surcharges de la CompareTo méthode retournent un nombre signé qui indique la valeur relative de cette instance et l’argument value
, comme indiqué dans le tableau suivant.
Valeur | Description |
---|---|
Inférieure à zéro | Cette instance est plus courte que value . |
Zéro | Cette instance est la même que value . |

paramètre en objet.
