Description

Contient un grand nombre de méthodes utilitaires statiques, utilisées dans les manipulations des chemins.

TPath est un enregistrement contenant seulement les méthodes statiques utilisées pour effectuer diverses opérations sur les chemins. Ne déclarez pas les variables de type TPath, puisque TPath n'a pas de champs ou de méthodes d'instance. Voici les opérations qui peuvent être accomplies en utilisant TPath :

  • Vérification de la justesse d'un nom de chemin ou de fichier
  • Extraction des diverses parties d'une chaîne de chemin
  • Génération de chemins uniques et temporaires

Remarque :  La plupart des méthodes exposées par TPath sont compatibles en signature à celles exposées par la classe Path du .NET Framework.
