Exemples

L’exemple suivant fait référence au répertoire parent d’un répertoire spécifié.

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" );
   
   // Get a reference to the parent directory of the subdirectory you just made.
   DirectoryInfo^ parentDir = dis->Parent;
   Console::WriteLine( "The parent directory of '{0}' is '{1}'", dis->Name, parentDir->Name );
   
   // Delete the parent directory.
   di->Delete( true );
}

    public static void Main()
    {

        DirectoryInfo parentDir = dis.Parent;
        Console.WriteLine("The parent directory of '{0}' is '{1}'", dis.Name, parentDir.Name);

        Dim dis As DirectoryInfo = di.CreateSubdirectory("SubDir")

        ' Get a reference to the parent directory of the subdirectory you just made.
        Dim parentDir As DirectoryInfo = dis.Parent
        Console.WriteLine("The parent directory of '{0}' is '{1}'", dis.Name, parentDir.Name)

        ' Delete the parent directory.
        di.Delete(True)
    End Sub
End Class

Remarques

Important

Dans .NET Framework, Parent retourne un chemin relatif. Dans .NET Core, Parent retourne un chemin complet.

Pour garantir un comportement cohérent entre les versions et rendre votre intention explicite, récupérez la valeur de l’une des propriétés suivantes sur le DirectoryInfo instance retourné par Parent.

  • Name, qui retourne le nom simple du répertoire (par exemple bin).
  • FullName, qui retourne le chemin absolu du répertoire.
