Mapping an ASMX Service Using Routing in ASP.NET MVC

Question

I wonder if there is a way to map the ASMX service URL, as it does with pages (using the method routes.MapPageRoute()).

When I tried to do this simply by pointing MapPageRoute to my service, I get an error

The type 'MvcApplication1.Services.EchoService' is not inherited from 'System.Web.UI.Page'.

I came across this question, trying to find the answer myself, and since I figured out how to do it, I decided that I would answer it.

, , , - ASP.NET ASP.NET MVC, -, URL-. URL- , ( URL- , -).

PageRouteHandler, RouteCollection.MapPageRoute, , System.Web.Page, -. :

using System;
using System.Web;
using System.Web.Routing;
using System.Web.Services.Protocols;

public class ServiceRouteHandler : IRouteHandler
{
    private readonly string _virtualPath;
    private readonly WebServiceHandlerFactory _handlerFactory = new WebServiceHandlerFactory();

    public ServiceRouteHandler(string virtualPath)
    {
        if( virtualPath == null )
            throw new ArgumentNullException("virtualPath");
        if( !virtualPath.StartsWith("~/") )
            throw new ArgumentException("Virtual path must start with ~/", "virtualPath");
        _virtualPath = virtualPath;
    }

    public IHttpHandler GetHttpHandler(RequestContext requestContext)
    {
        // Note: can't pass requestContext.HttpContext as the first parameter because that's
        // type HttpContextBase, while GetHandler wants HttpContext.
        return _handlerFactory.GetHandler(HttpContext.Current, requestContext.HttpContext.Request.HttpMethod, _virtualPath, requestContext.HttpContext.Server.MapPath(_virtualPath));
    }
}

public static Route MapServiceRoute(this RouteCollection routes, string routeName, string url, string virtualPath)

        throw new ArgumentNullException("routes");
    Route route = new Route(url, new RouteValueDictionary() { { "controller", null }, { "action", null } }, new ServiceRouteHandler(virtualPath));
    routes.Add(routeName, route);
    return route;
}

routes.MapServiceRoute("RouteName", "path/to/your/service", "~/actualservice.asmx");
