ASP.NET MVC: Execute code on all Actions (global OnActionExecuting?)

Question

Is there a \"global\" OnActionExecuting that I can override to have all my MVC actions (regardless of controller) do something when they get called? If so, how?

Answer 1

Create one class that Implements IActionFilter and/or IResultFilter:

public class FilterAllActions : IActionFilter, IResultFilter
{      
    public void OnActionExecuting(ActionExecutingContext filterContext)
    {
        throw new System.NotImplementedException();
    }

    public void OnActionExecuted(ActionExecutedContext filterContext)
    {
        throw new System.NotImplementedException();
    }

    public void OnResultExecuting(ResultExecutingContext filterContext)
    {
        throw new System.NotImplementedException();
    }

    public void OnResultExecuted(ResultExecutedContext filterContext)
    {
        throw new System.NotImplementedException();
    }
}

And register it on Global.asax

    protected void Application_Start()
    {
        //...
        RegisterGlobalFilters(GlobalFilters.Filters);
        //...
    }

    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new FilterAllActions());
    }
