在IIS6上使用ASP.NET MVC开发Web应用程序是一种强大而灵活的方式。ASP.NET MVC是一种基于模型-视图-控制器（Model-View-Controller，简称MVC）设计模式的框架，它允许开发人员更好地组织和管理代码，提高应用程序的可维护性和可扩展性。

csharp
using System.Web.Mvc;
public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }
}

html
    
    
Hello World!

csharp
using System.Web.Mvc;
using System.Web.Routing;
public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
}

csharp
using System.Web.Mvc;
using System.Web.Routing;
public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        RouteConfig.RegisterRoutes(RouteTable.Routes);
    }
}
