【问题描述】：

我有一个网站来管理餐馆的库存。这些是我的路线：

routes.MapRoute(
    "Inventory",                            
    "Inventory/{restaurantName}/{restaurantLocationId}/{code}",
    new { controller = "Inventory", action = "Index" },
    new[] { "MySite.Web.Controllers" }
);

routes.MapRoute(    // this route doesn't work
    "ListRestaurantInventory",
    "Inventory/List/{restaurantLocationId}/{code}",
    new { controller = "Inventory", action = "ListRestaurantInventoryItems" },
    new[] { "MySite.Web.Controllers" }
);

routes.MapRoute(
    "InventoryDetails",
    "Inventory/{restaurantName}/{restaurantLocationId}/{code}/Details/{restaurantInventoryItemId}",
    new { controller = "Inventory", action = "Details" },
    new[] { "MySite.Web.Controllers" }
);

问题在于ListRestaurantInventory 路线，如果我尝试导航到/Inventory/List/1/ABC，我会得到404。我的其他路线运行良好。

我真的不知道我的路线有什么问题。我是否需要更改路由顺序或 URL 中参数的顺序？

【解决方案1】：

应该按照从最具体到最不具体的顺序列出路线。

您的Inventory 路由将覆盖您的ListRestaurantInventory，因为您通过的每条路由都以Inventory 分段开头的4 个分段（例如/Inventory/List/1/ABC）将匹配它。这实质上使您的 ListRestaurantInventory 路由成为无法访问的执行路径。颠倒这 2 条路线的顺序将解决此问题。

routes.MapRoute(
    "ListRestaurantInventory",
    "Inventory/List/{restaurantLocationId}/{code}",
    new { controller = "Inventory", action = "ListRestaurantInventoryItems" },
    new[] { "MySite.Web.Controllers" }
);

routes.MapRoute(
    "Inventory",                            
    "Inventory/{restaurantName}/{restaurantLocationId}/{code}",
    new { controller = "Inventory", action = "Index" },
    new[] { "MySite.Web.Controllers" }
);

routes.MapRoute(
    "InventoryDetails",
    "Inventory/{restaurantName}/{restaurantLocationId}/{code}/Details/{restaurantInventoryItemId}",
    new { controller = "Inventory", action = "Details" },
    new[] { "MySite.Web.Controllers" }
);
