Ejemplos

En el ejemplo de código siguiente se muestra cómo usar el OpenMappedMachineConfiguration método para obtener todas las secciones del archivo de configuración.

   // 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);
     }
   }

' Access the machine configuration file using mapping.

    ' Get the machine.config file.
    Dim machineConfig As Configuration = _
        ConfigurationManager.OpenMachineConfiguration()
    ' Get the machine.config file path.

        As New ConfigurationFileMap( _
            machineConfig.FilePath)

    ' Map the application configuration file 
    ' to the machine configuration file.
    Dim config As Configuration = _
        ConfigurationManager. _
        OpenMappedMachineConfiguration( _

        MachineToRoamingUser

    ' Display the configuration file sections.
    Dim sections As  _
        ConfigurationSectionCollection = _
        config.Sections

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

    ' Get the sections in the machine.config.
    For Each section _
        As ConfigurationSection In sections
        Dim name As String = _
            section.SectionInformation.Name
        Console.WriteLine("Name: {0}", name)
    Next

Comentarios

Las opciones de configuración de la máquina se aplican a todo el equipo y a todas las aplicaciones que residen en él, a menos que se invaliden para la aplicación local. Los valores de configuración de la máquina se leen desde el archivo Machine.config de la versión que se está ejecutando actualmente de .NET Framework. El archivo Machine.config se encuentra en el subdirectorio siguiente:

%windir%\Microsoft.NET\Framework\version\config
