Esempio

Nell'esempio di codice seguente viene illustrato come usare il OpenMappedMachineConfiguration metodo per ottenere tutte le sezioni nel file di configurazione.

   // 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);
     }
   }

        As ConfigurationSection In sections
        Dim name As String = _

Commenti

Le impostazioni di configurazione del computer si applicano all'intero computer e a tutte le applicazioni che si trovano in esso, a meno che non venga sottoposto a override per l'applicazione locale. Le impostazioni di configurazione del computer vengono lette dal file Machine.config della versione attualmente in esecuzione di .NET Framework. Il file Machine.config si trova nella sottodirectory seguente:
