Examples

The following code example shows how to use the OpenMappedExeConfiguration method to obtain all sections that are contained by the configuration file.

   // Access a configuration file using mapping.
   // This function uses the OpenMappedExeConfiguration 
   // method to access a new configuration file.   
   // It also gets the custom ConsoleSection and 
   // sets its ConsoleElement BackgroundColor and
   // ForegroundColor properties to green and red
   // respectively. Then it uses these properties to
   // set the console colors.  
   public static void MapExeConfiguration()
   {

     // Get the application configuration file.
     System.Configuration.Configuration config =
       ConfigurationManager.OpenExeConfiguration(
             ConfigurationUserLevel.None);
   
     Console.WriteLine(config.FilePath);

     if (config == null)
     {
       Console.WriteLine(
         "The configuration file does not exist.");
       Console.WriteLine(
        "Use OpenExeConfiguration to create the file.");
     }

     // Create a new configuration file by saving 
     // the application configuration to a new file.
     string appName = 
       Environment.GetCommandLineArgs()[0];

     string configFile =  string.Concat(appName, 
       ".2.config");
     config.SaveAs(configFile, ConfigurationSaveMode.Full);

     // Map the new configuration file.
     ExeConfigurationFileMap configFileMap = 
         new ExeConfigurationFileMap();
     configFileMap.ExeConfigFilename = configFile;

     // Get the mapped configuration file
    config = 
       ConfigurationManager.OpenMappedExeConfiguration(
         configFileMap, ConfigurationUserLevel.None);

     // Make changes to the new configuration file. 
     // This is to show that this file is the 
     // one that is used.
     string sectionName = "consoleSection";

     ConsoleSection customSection =
       (ConsoleSection)config.GetSection(sectionName);

     if (customSection == null)
     {
         customSection = new ConsoleSection();
         config.Sections.Add(sectionName, customSection);
     }
     else
         // Change the section configuration values.
         customSection =
             (ConsoleSection)config.GetSection(sectionName);

     customSection.ConsoleElement.BackgroundColor =
         ConsoleColor.Green;
     customSection.ConsoleElement.ForegroundColor =
         ConsoleColor.Red;

     // Save the configuration file.
     config.Save(ConfigurationSaveMode.Modified);

     // Force a reload of the changed section. This 
     // makes the new values available for reading.
     ConfigurationManager.RefreshSection(sectionName);

     // Set console properties using the 
     // configuration values contained in the 
     // new configuration file.
     Console.BackgroundColor =
       customSection.ConsoleElement.BackgroundColor;
     Console.ForegroundColor =
       customSection.ConsoleElement.ForegroundColor;
     Console.Clear();

     Console.WriteLine();
     Console.WriteLine("Using OpenMappedExeConfiguration.");
     Console.WriteLine("Configuration file is: {0}", 
       config.FilePath);

Remarks

The ConfigurationUserLevel object determines the location of the configuration file being opened. It indicates whether the file has no user level (the configuration file is in the same directory as the application) or has a per-user level (the configuration file is in an application settings path determined by userLevel).

The ConfigurationUserLevel object determines the location of the configuration file that is being opened. It indicates whether the file has no user level (the configuration file is in the same directory as the application) or has a per-user level (the configuration file is in an application settings path that is determined by userLevel).
