如何在WebForm ASP.Net中模拟MVC路由？

string url = Request.RawUrl;
string[] segments = url.Split('/');

if (segments.Length > 1)
{
    string controller = segments[1];
    string action = segments.Length > 2 ? segments[2] : "Index";

    Server.Transfer($"~/{controller}.aspx?action={action}");
}

void Application_Start(object sender, EventArgs e)
{
    RegisterRoutes(RouteTable.Routes);
}

void RegisterRoutes(RouteCollection routes)
{
    routes.Add(new Route("{controller}/{action}", new CustomRouteHandler()));
}

public class CustomRouteHandler : IHttpHandler
{
    public bool IsReusable => false;

    public void ProcessRequest(HttpContext context)
    {
        string controller = context.Request.QueryString["controller"];
        string action = context.Request.QueryString["action"];

        switch (controller)
        {
            case "Home":
                ProcessHomeController(context, action);
                break;
            case "Product":
                ProcessProductController(context, action);
                break;
            // 添加其他控制器的处理逻辑
        }
    }

    private void ProcessHomeController(HttpContext context, string action)
    {
        if (action == "Index")
        {
            context.Server.Transfer("~/Home.aspx");
        }
        else if (action == "About")
        {
            context.Server.Transfer("~/About.aspx");
        }
        // 添加其他操作方法的处理逻辑
    }

    private void ProcessProductController(HttpContext context, string action)
    {
        if (action == "List")
        {
            context.Server.Transfer("~/ProductList.aspx");
        }
        else if (action == "Detail")
        {
            context.Server.Transfer("~/ProductDetail.aspx");
        }
        // 添加其他操作方法的处理逻辑
    }
}
