每次控制器方法结束时调用方法

Question

I have a static class called NotificationManager and every time a controller method is called, I want to store the ModelErrors in the NotificationManager.

However, inside the NotificationManager, I can't access the ModelState because it is not inside the actual controller.

Is there any way to automatically call a method once a controller method is finished, without having to write it in every single controller method?

NOTE: I need to use the values in the view.

Answer 1

You can create a global ActionFilter and override OnActionExecuted .

Alternatively, you could put a child action in the view.

Answer 2

Override the OnActionExecuted in your controller. You still have ViewData[]

protected override void OnActionExecuted(ActionExecutedContext filterContext)
{
    //Do your stuff
    base.OnActionExecuted(filterContext);
}

Answer 3

You can override methods in the Controller class to do this:
