And here is the example:

public class Class1
{
   public Class1()
   {
       Microsoft.Win32.RegistryKey key =
Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software\\Microsoft\\Window
s\\CurrentVersion\\Internet Settings");

       String keys[] = key.GetValueNames();

       for ( int counter = 0; counter < keys.length; counter++ )
           System.Console.WriteLine("Key: "+keys[counter].ToString() );

       System.Console.WriteLine("\n\n");
       System.Console.WriteLine("Proxy enabled

       System.Console.WriteLine("Proxy server

   }

   /** @attribute System.STAThread() */
   public static void main(String[] args)
   {
       new Class1();
   }
}
