Příklady

Následující příklad kódu ukazuje, jak pomocí OpenMappedExeConfiguration metody získat všechny oddíly, které jsou obsaženy v konfiguračním souboru.

   // 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.

Poznámky

Objekt ConfigurationUserLevel určuje umístění konfiguračního souboru, který se otevírá. Označuje, jestli soubor nemá žádnou úroveň uživatele (konfigurační soubor je ve stejném adresáři jako aplikace), nebo jestli má úroveň pro jednotlivé uživatele (konfigurační soubor je v cestě nastavení aplikace určené pomocí userLevel).
