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.

this answer helps you? http://stackoverflow.com/a/2032154/330606 — , Feb 14 '12 at 12:51

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.

You can access the RequestContext, please refer to my answer. — Medeni Baykal, Mar 15 '13 at 12:08

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.

Create an HttpContextBase from the Current HttpContext, and from that you can generate a UrlHelper:

// Create Http Context Base from current Context
var contextBase = new System.Web.HttpContextWrapper(System.Web.HttpContext.Current);
// Get its request context
System.Web.Routing.RequestContext requestContext = contextBase.Request.RequestContext;
// Build url helper from request context
var urlHelper = new System.Web.Mvc.UrlHelper(requestContext);
