Accessing RequestContext from global.asax

Question

Does anyone know how to get the current RequestContext from the Application_Error event in global.asax?? My problem is that i need to do a redirect, and thereby need to have the url generated using UrlHelper - which takes the aformentioned RequestContext.

Answer 1

While there is no direct way of accessing the RequestContext, you can create one yourself:

RequestContext context = new RequestContext(new HttpContextWrapper(HttpContext.Current), RouteTable.Routes.GetRouteData(new HttpContextWrapper(HttpContext.Current)))

So the UrlHelper can be constructed via:

UrlHelper helper = new UrlHelper(new RequestContext(new HttpContextWrapper(HttpContext.Current), RouteTable.Routes.GetRouteData(new HttpContextWrapper(HttpContext.Current))));

Not pretty, but it gets the job done.

Answer 2

You can access the request context using

HttpContext.Current.Request.RequestContext

Or, if you're in the Global.asax you can use

Context.Request.RequestContext

directly.
