Beispiele

Im folgenden Codebeispiel wird gezeigt, wie Sie die OpenMachineConfiguration -Methode verwenden, um alle Abschnitte abzurufen, die in der Konfigurationsdatei enthalten sind.

   // 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.

Hinweise

Computerkonfigurationseinstellungen gelten für den gesamten Computer und alle Anwendungen, die sich darauf befinden, es sei denn, sie werden für die lokale Anwendung überschrieben. Computerkonfigurationseinstellungen werden aus der Machine.config-Datei der derzeit ausgeführten Version von .NET Framework gelesen. Die Machine.config Datei befindet sich im folgenden Unterverzeichnis:
