路由在我的asp.net應用中不起作用

Question

我有4條路由定義了5個不同的URL。與RouteDebugger測試了很多，但無法解決。

的問題是，前2個鏈接始終使用{控制器}/{行動}/{ID}這條路線是目錄root1而不能重定向到正確的頁面。

鏈接

@Html.ActionLink("Go Index by name", "Page", "Home", new { name="contact"}, null) 

@Html.ActionLink("Go Index by id", "Index", "Admin", new { id=2}, null) 


@Html.ActionLink("Go Index by id and name", "Page", "Home", new { name = "contact", id = 2 }, null) 


@Html.ActionLink("Root Admin", "Index", "Admin") 


@Html.ActionLink("Root", "Index", "Home") 

這裏是Map.Route

routes.MapRoute("root1", 
     "{controller}/{action}/{id}", 
     new { controller = "Admin", action = "Index" }); 

    routes.MapRoute("root2", 
     "{controller}/{action}/{name}", 
     new { controller = "Home", action = "Page" }); 

    routes.MapRoute("root3", 
     "{controller}/{action}/{name}/{id}", 
     new { controller = "Home", action = "Page" }); 

    routes.MapRoute("root4", 
     "{controller}/{action}/{name}", 
     new { controller = "Home", action = "Index", name = UrlParameter.Optional }); 

Answer 1

這些是我建立的路線，它似乎正確地擊中每一個。

請注意，root3已被移動到頂端，因爲root2也會匹配。此外，作爲國王朱利安驗證了root1與id建議

路線：

@Html.ActionLink("Root Admin", "Index", "Admin") 

不應該因爲有和沒有默認idname分別在路線定義匹配root1也不root2

routes.MapRoute("root3", 
    "{controller}/{action}/{name}/{id}", 
     new { controller = "Home", action = "Page" }); 

routes.MapRoute("root1", 
     "{controller}/{action}/{id}", 
     new { controller = "Admin", action = "Index" }, 
     new { id = @"\d+" }); 

routes.MapRoute("root2", 
     "{controller}/{action}/{name}", 
     new { controller = "Home", action = "Page" }); 

routes.MapRoute("root4", 
     "{controller}/{action}/{name}", 
     new { controller = "Home", action = "Index", name = UrlParameter.Optional  
}); 

Answer 2

添加約束你的路由。例如：

routes.MapRoute(
    "root1", 
    "{controller}/{action}/{id}", 
    new { controller = "Admin", action = "Index" }, 
    new {id = @"\d+" } 
); 

確保root1只在id爲整數時才匹配。否則，root2會抓住它。
