Exemples

L’exemple de code suivant montre comment utiliser la OpenMachineConfiguration méthode pour obtenir toutes les sections contenues dans le fichier de configuration.

   // Access the machine configuration file using mapping.
   // The function uses the OpenMappedMachineConfiguration 
   // method to access the machine configuration. 
   public static void MapMachineConfiguration()
   {
     // Get the machine.config file.
     Configuration machineConfig =
       ConfigurationManager.OpenMachineConfiguration();
     // Get the machine.config file path.
     ConfigurationFileMap configFile =
       new ConfigurationFileMap(machineConfig.FilePath);

     // Map the application configuration file to the machine 
     // configuration file.
     Configuration config =
       ConfigurationManager.OpenMappedMachineConfiguration(
         configFile);

     // Get the AppSettings section.
     AppSettingsSection appSettingSection =
       (AppSettingsSection)config.GetSection("appSettings");
     appSettingSection.SectionInformation.AllowExeDefinition =
         ConfigurationAllowExeDefinition.MachineToRoamingUser;

     // Display the configuration file sections.
     ConfigurationSectionCollection sections = 
       config.Sections;

     Console.WriteLine();
     Console.WriteLine("Using OpenMappedMachineConfiguration.");
     Console.WriteLine("Sections in machine.config:");

     // Get the sections in the machine.config.
     foreach (ConfigurationSection section in sections)
     {
         string name = section.SectionInformation.Name;
         Console.WriteLine("Name: {0}", name);
     }
   }

Remarques

Les paramètres de configuration de l’ordinateur s’appliquent à l’ensemble de l’ordinateur et à toutes les applications qui résident sur celui-ci, sauf s’ils sont remplacés pour l’application locale. Les paramètres de configuration de l’ordinateur sont lus à partir du fichier Machine.config de la version en cours d’exécution de .NET Framework. Le fichier Machine.config se trouve dans le sous-répertoire suivant :
