  我就是这样做的：

  routes.MapRoute("ProductDetail", "Products/{id}", _
      New With {.controller = "Products", .action = "Details", .id = ""},
      New With {.id = @"\d+"})
      //constraint, so this route will not catch a category name
      //or the URL below
  
  routes.MapRoute("ProductList", "Products/category/{id}", _
      New With {.controller = "Products", .action = "ListByCatId", .id = ""})
  
  routes.MapRoute("Category", "Products/categories/{id}", _
      New With {.controller = "Products", .action= "ListCategories", .id = ""})
      //for the route above, let it fall to the ListCategories action
      //and in that action take a nullable of int as a parameter.
      //if the id parameter has a value, 
      //    return DetailsCategories(id)
      //else list the categories.
  
  
  routes.MapRoute("Default", "{controller}/{action}/{id}", _
      New With {.controller = "Home", .action = "Index", .id = ""})
  

  至于具有两个具有相同名称的控制器，是的，您可以使用不同的命名空间并在mapRoute方法中指定它们 . 有一个重载需要 string[] namespaces . 只需确保在路由时为控制器指定名称空间 .

  是的，如果您需要添加与默认值不对应的其他路由，请继续执行此操作 . 您将需要在默认路由上添加其他自定义路由，并在添加路由时使用从窄到宽的顺序（以便首先进行窄匹配） . 我建议让你的控制器动作尽可能地与你想要的默认命名相匹配 .

  代替：

  http://website/products/id               > ProductsController Action=Details
  http://website/products/category/id      > ProductsController Action=ListByCatId
  http://website/products/categories/      > ProductsController Action=ListCategories
  http://website/products/categories/id    > ProductsController Action=DetailsCategories
  

  使用：

  http://website/product/id               > ProductsController Action=Index
  http://website/product/category/id      > ProductsController Action=category
  http://website/product/      > ProductsController Action=Index
  http://website/product/categories/id    > ProductsController Action=categories
  

  您的Index方法可以采用可为空的int（int？Id），其中Id对应于定义的产品 . 如果Id.HasValue为false，则返回ListCategories结果 .

  public ActionResult Index(int? Id)
  {
    if (Id.HasValue) return Details(Id.Value);
    return ListCategories();
  }
  

  这可以使您的附加路由更清洁 .
