使用注册路由更新 asp.net Web 表单中的路由

Question

我正在一个 asp.net 的Web表单应用程序中工作。我已经使用RegisterRoutes在其中实现了URL路由，如下所示：

  void Application_Start(object sender, EventArgs e)
    {
        // Code that runs on application startup
        RegisterRoutes(RouteTable.Routes);       
    } 

  void RegisterRoutes(RouteCollection routes)
        {
           int language = 2;
            routes.MapPageRoute("City1Route", "vacancies/" + HRTabs.GetCityTabLink(1, language), "~/City1.aspx");
            routes.MapPageRoute("City2Route", "vacancies/" + HRTabs.GetCityTabLink(2, language), "~/City2.aspx");
            routes.MapPageRoute("City3Route", "vacancies/" + HRTabs.GetCityTabLink(3, language), "~/City3.aspx");
            routes.MapPageRoute("City4Route", "vacancies/" + HRTabs.GetCityTabLink(4, language), "~/City4.aspx");
            routes.MapPageRoute("default", "vacancies/{language}", "~/City1.aspx");
        }

我正在使用数据库中的值创建映射。

在此应用程序中。我正在更新表（路由）。我希望在保存功能完成后立即自动描述这些更改，但由于 Registerroutes 在应用程序启动功能中，因此不会发生。

如果我尝试调用 RegisterRoutes（RouteTable.Routes）; 单击"保存"按钮，出现"路由"已注册的错误。

请向我建议一个解决方案。

在注册更新的路由之前，请尝试清除路由表。例如：

void RegisterRoutes(RouteCollection routes)
    {
        int language = 2;
        routes.Clear();
        routes.MapPageRoute("City1Route", "vacancies/" + HRTabs.GetCityTabLink(1, language), "~/City1.aspx");
        routes.MapPageRoute("City2Route", "vacancies/" + HRTabs.GetCityTabLink(2, language), "~/City2.aspx");
        routes.MapPageRoute("City3Route", "vacancies/" + HRTabs.GetCityTabLink(3, language), "~/City3.aspx");
        routes.MapPageRoute("City4Route", "vacancies/" + HRTabs.GetCityTabLink(4, language), "~/City4.aspx");
        routes.MapPageRoute("default", "vacancies/{language}", "~/City1.aspx");
    }
