MVC自定义路由中的多个级别

您可以使用自定义

Routebase

public class PageInfo{    // VirtualPath should not have a leading slash    // example: events/conventions/mycon    public string VirtualPath { get; set; }    public Guid Id { get; set; }}public class CustomPageRoute    : Routebase{    private object synclock = new object();    public override RouteData GetRouteData(HttpContextbase httpContext)    {        RouteData result = null;        // Trim the leading slash        var path = httpContext.Request.Path.Substring(1);        // Get the page that matches.        var page = GetPageList(httpContext) .Where(x => x.VirtualPath.Equals(path)) .FirstOrDefault();        if (page != null)        { result = new RouteData(this, new MvcRouteHandler()); // Optional - make query string values into route values. this.AddQueryStringParametersToRouteData(result, httpContext); // TODO: You might want to use the page object (from the database) to // get both the controller and action, and possibly even an area. // Alternatively, you could create a route for each table and hard-pre // this information. result.Values["controller"] = "CustomPage"; result.Values["action"] = "Details"; // This will be the primary key of the database row. // It might be an integer or a GUID. result.Values["id"] = page.Id;        }        // importANT: Always return null if there is no match.        // This tells .NET routing to check the next route that is registered.        return result;    }    public override VirtualPathData GetVirtualPath(RequestContext requestContext, RoutevalueDictionary values)    {        VirtualPathData result = null;        PageInfo page = null;        // Get all of the pages from the cache.        var pages = GetPageList(requestContext.HttpContext);        if (TryFindMatch(pages, values, out page))        { if (!string.IsNullOrEmpty(page.VirtualPath)) {     result = new VirtualPathData(this, page.VirtualPath); }        }        // importANT: Always return null if there is no match.        // This tells .NET routing to check the next route that is registered.        return result;    }    private bool TryFindMatch(IEnumerable<PageInfo> pages, RoutevalueDictionary values, out PageInfo page)    {        page = null;        Guid id = Guid.Empty;        // This example uses a GUID for an id. If it cannot be parsed,        // we just skip it.        if (!Guid.TryParse(Convert.ToString(values["id"]), out id))        { return false;        }        var controller = Convert.ToString(values["controller"]);        var action = Convert.ToString(values["action"]);        // The logic here should be the inverse of the logic in         // GetRouteData(). So, we match the same controller, action, and id.        // If we had additional route values there, we would take them all         // into consideration during this step.        if (action == "Details" && controller == "CustomPage")        { page = pages     .Where(x => x.Id.Equals(id))     .FirstOrDefault(); if (page != null) {     return true; }        }        return false;    }    private void AddQueryStringParametersToRouteData(RouteData routeData, HttpContextbase httpContext)    {        var queryString = httpContext.Request.QueryString;        if (queryString.Keys.Count > 0)        { foreach (var key in queryString.AllKeys) {     routeData.Values[key] = queryString[key]; }        }    }    private IEnumerable<PageInfo> GetPageList(HttpContextbase httpContext)    {        string key = "__CustomPageList";        var pages = httpContext.Cache[key];        if (pages == null)        { lock(synclock) {     pages = httpContext.Cache[key];     if (pages == null)     {         // TODO: Retrieve the list of PageInfo objects from the database here.         pages = new List<PageInfo>()         {  new PageInfo()   {       Id = new Guid("cfea37e8-657a-43ff-b73c-5df191bad7c9"),       VirtualPath = "somecategory/somesubcategory/content1"   },  new PageInfo()   {       Id = new Guid("9a19078b-2d7e-4fc6-ae1d-3e76f8be46e5"),       VirtualPath = "somecategory/somesubcategory/content2"   },  new PageInfo()   {       Id = new Guid("31d4ea88-aff3-452d-b1c0-fa5e139dcce5"),       VirtualPath = "somecategory/somesubcategory/content3"   }         };         httpContext.Cache.Insert(  key: key,   value: pages,   dependencies: null,   absoluteExpiration: System.Web.Caching.Cache.NoAbsoluteExpiration,   slidingExpiration: TimeSpan.FromMinutes(15),   priority: System.Web.Caching.CacheItemPriority.NotRemovable,   onRemoveCallback: null);     } }        }        return (IEnumerable<PageInfo>)pages;    }}

您可以这样向MVC注册路由。

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");// Case sensitive lowercase URLs are faster. // If you want to use case insensitive URLs, you need to// adjust the matching pre in the `Equals` method of the CustomPageRoute.routes.LowercaseUrls = true;routes.Add(    name: "CustomPage",     item: new CustomPageRoute());routes.MapRoute(    name: "Default",    url: "{controller}/{action}/{id}",    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional });

上面假设您有

CustomPageController

Details

public class CustomPageController : Controller{    public ActionResult Details(Guid id)    {        // Do something with id        return View();    }}

如果希望路由转到其他控制器操作（甚至使它们成为构造函数参数），则可以更改路由。
