11.4. Contrôle de la partie module
Chaque module peut-être contrôlé d'une manière similaire, vous trouverez ci-dessous un simple
programme d'exemple affichant les principaux paramètres d'un module et permettant d'activer la
balise de localisation.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace
ConsoleApplication1
{
class
Program
{
static
void
usage()
{
string
execname
Console.WriteLine("Usage:");
Console.WriteLine(execname
System.Threading.Thread.Sleep(2500);
Environment.Exit(0);
