var routeData = new RouteData();
// controller and action are compulsory
routeData.Values["action"] = "index";
routeData.Values["controller"] = "foo";
// some additional route parameter
routeData.Values["foo"] = "bar";
IController fooController = new FooController();
var rc = new RequestContext(new HttpContextWrapper(HttpContext),routeData);
fooController.Execute(rc);

我个人使用这种方法来处理我的应用程序内的错误.我把它放在Application_Error中,并为停留在初始HTTP请求的上下文中的自定义错误页面执行错误控制器.您还可以在routeData哈希中放置复杂对象,然后将这些复杂对象作为操作参数返回.我使用它来传递错误控制器操作发生的实际异常.

为了解析其路线数据令牌的URL,考虑到当前路线,您可以：

var request = new HttpRequest(null,"http://foo.com/Home/Index","id=1");
var response = new HttpResponse(new StringWriter());
var httpContext = new HttpContext(request,response);
var routeData = RouteTable.Routes.GetRouteData(new HttpContextWrapper(httpContext));
var values = routeData.Values;
var action = values["action"];
var controller = values["controller"];
