ASP.NET MVC - MapRoute versus routes.Add (and 404s)
提问by BuddyJoe
I'm just getting started with ASP.NET MVC.
我刚刚开始使用 ASP.NET MVC。
What is the difference between MapRoute and routes.Add ? Should I just be using MapRoute? Can I map multiple routes? Which "maps" take precedence... those you called first or last?
MapRoute 和 routes.Add 有什么区别？我应该只使用 MapRoute 吗？我可以映射多条路线吗？哪些“地图”优先……您首先调用的还是最后调用的那些？
I'd like to be able to do something similiar to the StackOverflow does for users.
But I would like the URL to fit this pattern:
"User/{domain}/{username}" to be routed to a UserController
我希望能够做一些类似于 StackOverflow 为用户所做的事情。但我希望 URL 适合这种模式：
“User/{domain}/{username}” 被路由到 UserController
and for all other requests to do the typical ASP.NET MVC routing. ex:
以及执行典型 ASP.NET MVC 路由的所有其他请求。前任：
routes.MapRoute(
"Default", "{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = "" }
);
UPDATE:
When using the URL: http://localhost:3962/User/MYDOMAIN/BTYNDALL
I get the error: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.
更新：
使用 URL 时：http://localhost:3962/User/MYDOMAIN/BTYNDALL
我收到错误：HTTP 404。您要查找的资源（或其依赖项之一）可能已被删除，名称已更改，或暂时不可用。
Here is the code I'm using:
这是我正在使用的代码：
public class MvcApplication : System.Web.HttpApplication
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"User",
"User/{domain}/{username}",
new { controller = "User", action = "Index" }
);
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = "" }
);
}
protected void Application_Start()
{
RegisterRoutes(RouteTable.Routes);
}
}

Your User controller should have
你的用户控制器应该有
public class UserController : Controller {
public ActionResult Index(string domain, string username) { return View(); }
}
The two variables on the Index method of the user controller get picked up from the route.
用户控制器的 Index 方法上的两个变量从路由中获取。

MapRoute()is an extension method over Routes.Add(). Use MapRoute(), unless you need to do something more complex than it allows.
MapRoute()是一种扩展方法Routes.Add()。使用MapRoute(), 除非你需要做一些比它允许的更复杂的事情。
Routes are evaluated in the order they are defined, so those you called first.
路由按照定义的顺序进行评估，所以你首先调用的那些。

Use!
用！
public class MvcApplication : System.Web.HttpApplication
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"User",
"User/{domain}/{username}",
new { controller = "User", action = "Index", username= UrlParameter.Optional }
);
}
protected void Application_Start()
{
RegisterRoutes(RouteTable.Routes);
}
}
