  Self-host this.Url.Route

  Apr 25, 2012 11:59 AM|LINK

  Trying to access the current URL as below succeeds in IIS host:

  var uri = this.Url.Route(null, new { id = value.Id });

  but throws 'ArgumentNullException' exception with self-host. The error message is: 'Value cannot be null. Parameter name: name' and stack trace:

  at System.Web.Http.HttpRouteCollection.GetVirtualPath(HttpControllerContext controllerContext, String name, IDictionary`2 values)
  at System.Web.Http.Routing.UrlHelper.GetHttpRouteHelper(HttpControllerContext controllerContext, String routeName, IDictionary`2 routeValues)
  at System.Web.Http.Routing.UrlHelper.GetHttpRouteHelper(HttpControllerContext controllerContext, String routeName, Object routeValues)
  at System.Web.Http.Routing.UrlHelper.Route(String routeName, Object routeValues)
  at MyProj.Services.DataService.Controllers.MessageController.Post(MessageDto value) in C:\...\MessageController.cs:line 93
  at lambda_method(Closure , Object , Object[] )
  at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.Execute(Object instance, Object[] arguments)
  at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.Execute(HttpControllerContext controllerContext, IDictionary`2 arguments)
  at System.Web.Http.Controllers.ApiControllerActionInvoker.<>c__DisplayClass2.<InvokeActionAsync>b__0()
  at System.Threading.Tasks.TaskHelpers.RunSynchronously[TResult](Func`1 func, CancellationToken cancellationToken)

  Everything else seems to work otherwise and all routes are correctly set-up. Is this a bug? Any ideas?

  I suspect that this is because there is no httpcontext in a self-hosted environment.

  Also, are you meaning to pass null as the route name?

  Yes basically you can't pass

  Route(routeName = null, ...)

   and I'm curious as to why it does work with IIS and not self-host.

  Yes I've noticed the behavioral differences between ASP.NET host and self-host. I'll see what happens w/ the RTM.
