Question

I have a static function and I need to call specific controller/action with parameters and get the result.
How can this be done?

Answer 1

You can create an instance of that particular controller and then use the instance’s Execute() method to execute the controller.

I do something similar in my Application_Error handler:

var routeData = new RouteData();
routeData.Values["controller"] = "Error";
routeData.Values["action"] = "General";
routeData.Values["exception"] = exception;

IController errorsController = new ErrorController();
var rc = new RequestContext(new HttpContextWrapper(Context), routeData);
try
{
    errorsController.Execute(rc);
}
catch (Exception ex)
{
    // Appropriate error handling.
}
