Code from MSDN

{
    // Get the application configuration file path.
    string exeFilePath = System.IO.Path.Combine(
        Environment.CurrentDirectory, "ConfigurationManager.exe.config");
    // HERE !!!     
    // Map to the application configuration file.
    ExeConfigurationFileMap configFile = new ExeConfigurationFileMap();
    configFile.ExeConfigFilename = exeFilePath;

    Configuration config =
        ConfigurationManager.OpenMappedExeConfiguration(configFile,
        ConfigurationUserLevel.None);

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

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

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