ASP.NET MVC: execute code for all actions (global OnActionExecuting?)

Question

Is there a “global” OnActionExecuting that I can override so that all my MVC actions (regardless of the controller) do something when they are called? If so, how?

Answer 1

Nope. The easiest way to do this is to write a common base class in which your entire class subclasses your controller, and then apply an action filter to that base class or override its OnActionExecuting () method.

Asp.net MVC3 Added Support for Global Filters

From the ScottGu blog:

ASP.NET MVC "" , "". , , :

. ASP.NET MVC 3 , . , GlobalFilters. RegisterGlobalFilters() Global.asax , ( Application_Start()):

MVC 3 , , , (: http- ..). (DI).

Answer 3

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());
    }
