Exemples

L’exemple suivant génère les codes de hachage de plusieurs TimeSpan objets à l’aide de la GetHashCode méthode .

// Example for the TimeSpan::GetHashCode( ) method.
using namespace System;

   // Create a hash code and a string representation of 
   // the TimeSpan parameter.

   // does not contain milliseconds.

Remarques

Deux TimeSpan objets peuvent avoir le même code de hachage, même s’ils représentent des valeurs temporelles différentes.
