Question

I need to use System.Web.Routing.RequestContext in a view model in order to call HtmlHelper.GenerateLink().

In MVC 1.0 it was possible to get the context statically by casting the current IHttpHandler:

 var context = ((MvcHandler) HttpContext.Current.CurrentHandler).RequestContext;

Now the project has been upgraded to MVC 2.0 and this exception is thrown on the cast:

Unable to cast object of type ‘ServerExecuteHttpHandlerWrapper’ to type ‘System.Web.Mvc.MvcHandler’.

I’m not sure if it’s relevant but this is being run in .NET 4.0 on IIS6.

I don’t know what you wanna do with the System.Web.Routing.RequestContext? check out:

var context = new HttpContextWrapper(System.Web.HttpContext.Current);
var routeData = RouteTable.Routes.GetRouteData(context);

// Use RouteData directly:
var controller = routeData.Values["controller"];

// Or with via your RequestContext:
var requestContext = new RequestContext(context, routeData);
controller = requestContext.RouteData.Values["controller"]
