Exemples

L’exemple suivant illustre la suppression d’un répertoire. Étant donné que le répertoire est supprimé, commencez par commenter la Delete ligne pour tester l’existence du répertoire. Supprimez ensuite les marques de commentaire de la même ligne de code pour tester que le répertoire a été supprimé avec succès.

using namespace System;
using namespace System::IO;
int main()
{
   
   // Make a reference to a directory.
   DirectoryInfo^ di = gcnew DirectoryInfo( "TempDir" );
   
   // Create the directory only if it does not already exist.
   if (  !di->Exists )
      di->Create();

   
   // Create a subdirectory in the directory just created.
   DirectoryInfo^ dis = di->CreateSubdirectory( "SubDir" );
   
   // Process that directory as required.
   // ...
   // Delete the subdirectory. The true indicates that if subdirectories
   // or files are in this directory, they are to be deleted as well.
   dis->Delete( true );
   
   // Delete the directory.
   di->Delete( true );

Remarques

Si le n’a pas de DirectoryInfo fichiers ou de sous-répertoires, cette méthode supprime le DirectoryInfo même si recursive est false. La tentative de suppression d’un DirectoryInfo qui n’est pas vide lorsque recursive lève false un IOException.
